We recently announced the retirement of Bill Merritt after 25 years at the company and nearly 16 years serving as InterDigital’s president and CEO. During Bill’s quarter-century tenure at InterDigital, his contributions and leadership led the company through many significant changes and expansions.

Here’s a snapshot of the last 25 years of achievement at InterDigital – truly a legacy to merit, and a legacy for Bill Merritt.

 

1996: Bill joins InterDigital as General Patent Counsel. Over the next nine years, Bill came to lead and become president of InterDigital Technology Corporation, a subsidiary of InterDigital Communications, and was largely responsible for establishing and building out the world-class licensing program InterDigital has today.

1997: InterDigital demonstrated a broadband CDMA solution that delivered video over wireless – three years before the first commercial 3G networks were launched in 2000.

1998: InterDigital forged a four-year partnership with Nokia to leverage InterDigital’s wideband patent position and develop 3G cellular phones.

2005: After nearly a decade at the company, Bill was appointed InterDigital’s President and CEO and member of the Board of Directors.

2000s: Throughout the 2000s and early 2010s, InterDigital was at the forefront of developing 4G and 5G technologies. With representation in all major global wireless standards organizations, InterDigital has helped develop and shape technologies in every aspect of the network – from handsets to base stations and mobile edge computing; from IoT sensors to streaming video and beyond.

2007-2008: InterDigital develops and launches its SlimChip mobile broadband modem at MWC, delivering performance hailed by Signals Research among the industry’s best.

2012: Intel acquires <10% of InterDigital’s patent portfolio for $375 million.

2013: From small to significant: following arbitration win, license with Apple ODM Pegatron grows to 37% of revenue. InterDigital signs agreement to arbitrate with Huawei, leading to historic first Chinese license with market leader.

2013: InterDigital demonstrates working 5G platform at Mobile World Congress.

2013: Bloomberg recognizes InterDigital as most profitable company in the US on a per worker basis, and names Bill Merritt among “Tech’s Top Turnaround Artists.”

2014: InterDigital signs landmark 10-year license agreement with Samsung.

2018-2019: Under Bill’s direction and leadership, he created one of the largest long-term R&D and licensing companies in the world with the acquisition of the Technicolor Patent and Research & Innovation (R&I) organizations. The acquisition expanded InterDigital’s research team and capabilities far beyond wireless to include video, AR, immersive content, AI, and other key areas.

2020: Bill took InterDigital to lead the industry in launching a licensing transparency initiative to make expanded information about the company’s standards essential patent (SEP) licensing rate program, rate structure, licensing and arbitration principles, and important data about the SEP portfolio, more readily accessible. The launch set an industry standard and highlighted the fairness and flexibility of our licensing approach.

2020: InterDigital pioneered licensing relationships with leading Chinese telecommunications device makers. In January, InterDigital resolved a nine-year licensing dispute by signing a license with ZTE, and later that year in April, InterDigital signed a licensing deal with China’s device maker Huawei.

2021: Under Bill’s leadership, InterDigital has grown from a net loss position with roughly one year’s working capital to just under $1 billion in cash with just under $1.7 billion returned to shareholders over the last 15 years.

This edition of “Getting to Know You” takes an in-depth look at Liren Chen, who on April 5th assumed the role of InterDigital’s President and CEO.

Following an introductory All Hands, InterDigital employees were introduced to Liren and given an insider pass to better understand his background, his drive to join InterDigital, and how he might lead in the path ahead. Here are some of the highlights of the conversation:

 

Early Life and Studies

  • Not unlike the topology of Delaware’s Eastern Shore, Liren Chen was born and raised in Qingdao, home to beautiful beaches and China’s famous Qingdao beer.
  • After earning his bachelor’s degree in Automation from Tsinghua University in Beijing, where he also met his wife of 26 years, Liren came to the United States in 1994 to attend the University of Maine under full scholarship, where he earned his M.S.E.E.
  • Liren joined Qualcomm after receiving his masters, and while working earned his J.D. degree from the University of San Diego, as well as an MBA from San Diego State University.

Career at Qualcomm

  • Prior to joining InterDigital, Liren’s most recent role was Senior Vice President and Global Head of IP.
  • Liren first joined Qualcomm as a software engineer responsible for implementing products for network management software and later spent more than five years working in corporate R&D. It was during this time that Liren developed most of his nearly 120 worldwide patents.
  • Later, Liren transitioned to spend more than seven years in Qualcomm’s IP department running essentially “every single functional aspect of IP creation – all the way to portfolio management, litigation readiness, and patent assertions.”
  • Liren was closely involved in developing and driving Qualcomm’s technology-driven IP strategy, and in 2016 joined the Qualcomm Licensing business responsible for technology, business strategy, and ecosystem development.

Reflecting on Similarities

  • When reflecting on his tenure at Qualcomm and new responsibilities as President and CEO of InterDigital, Liren noted that commonalities between the companies’ values helped make the transition smoother.
  • He specifically highlighted that Qualcomm and InterDigital share similarities in the ways they both “drive fundamental research, put value of IP over everything else, deliver value over a long period of time through multiple generations of wireless, and express a willingness, and strong track record, in defending their business model through arbitration or litigation.”
  • Moreover, having led multiple functional areas of the Qualcomm licensing division, Liren strongly resonated with a phrase often used to describe InterDigital’s impact – ‘We punch above our weight class.’ “That is a spirit I share,” he confidently replied.
  • In his words, Liren sees the move to InterDigital as a “great career opportunity,” but also a chance to bring his unique expertise and value to the company.
  • Given this background, Liren made clear that his interest in InterDigital stemmed from the company being a leading “fundamental technology developer and a major patent holder, both based on both the size and quality of the portfolio.”
  • In addition to the professionalism and caliber of InterDigital’s research and leadership, Liren also highlighted the timing of his transition, acknowledging that it comes when the lessons he has learned throughout his career will be most useful to InterDigital’s goals.

Driving Technology Leadership

  • In the all-hands, Liren made clear his belief that “the future is very bright for the technology that InterDigital develops,” and identified three technology areas that excite him most.
  • First, he reiterated the importance of InterDigital’s longtime foundation – connectivity, specifically wireless and cellular communications, including 5G and next G technologies alongside the Wi-Fi evolution.
  • Next, he noted “the multimedia area is super important from my perspective,” citing the massive impact of streaming video on internet traffic and the enormous potential for breakthrough technology in video codecs, audio codecs, and more.
  • He also noted that he is “a huge believer in artificial intelligence and machine learning.” 
  • Finally, he expressed excitement in exploring the space and opportunities where these three technologies – 5G wireless, video codecs, and AI – converge.
  • Liren reminded his new colleagues that the latest smart phones launches have already highlighted the features that stem from these convergences, which amplifies the importance and impact of InterDigital’s research and standards contributions to this industry sector, and beyond.

In closing, Liren shared a principle that he said will guide his first few months with the company: “There is a reason we have two ears and one mouth. We should listen more than we speak!”

It is a shame that February, the shortest month of the year, is also the month we celebrate Black History, and the myriad contributions from Black and African Americans across the country and around the globe. Black inventors are responsible for some of our most valued and often used amenities, including the three-light stoplight (Garrett Morgan; Patent No. 1,475,074), refrigerated trucks (Frederic McKinley Jones, U.S. Patent 2,780,923), automatic elevator doors (Alexander Miles; U.S. Patent 371,207), the home security system (Mary Van Britten Brown, U.S. Patent 3,482,037), and more. Born enslaved, Sarah Boone was the first Black woman to receive a patent (U.S. Patent 473,563) in 1892 for creating the “improved” ironing boards we use today. (The original ironing board design was patented by Elijah McCoy, a prolific Black innovator and rumored namesake of the phrase “the real McCoy”.) In the centuries since, Black women and men have developed countless solutions that improve our lives, often while facing racism and societal prejudices in their own.

At InterDigital, we are committed to supporting innovation and excellence in all communities. It is this spirit that moves us forward and makes our lives boundless. That’s why we are so proud of our partnership with Delaware State University, a historically black college and university (HBCU) centering STEM education and fostering the next generation of Black, Indigenous, and people of color (BIPoC) engineers, scientists, and innovators.

In this edition of Getting to Know You, Corporate Communications interviews Jean Bolot, InterDigital's Head of AI Labs, to explore the department’s latest news, unveil InterDigital's very first mobile app, and reveal surprising answers about the best AI Companion.

Jean Bolot

Corporate Comms: Jean, as Head of AI Labs, you lead one of InterDigital’s most cutting-edge and experimental departments. Following last year’s historic events, do you think that 2021 will be a year for AI? Did the events of last year change our relationship or need for AI algorithms and innovation?

Jean Bolot: For the past few years it feels like every year has been “the year of AI,” and rightly so because AI certainly has been a megatrend of the decade. But you are correct, and I think AI will still be in the spotlight in 2021. 


Frankly, I don’t know how much AI has been used in the fight against COVID – was it a plus, or really a critical piece? But independent of that, there were several noteworthy AI advances in 2020. These include the development of ethical AI to address issues of bias in data or algorithms; the use of deep learning to discover Halicin, a brand new type of antibiotics, or to understand how proteins fold – which is one of the most fundamental problems in biology with dramatic implications for how our cells and tissues operate, and the release of GPT-3, which is a new type of giant neural network called transformers. These transformers are 2000 times larger than the networks today and are revolutionizing the processing and automated generation of text.

CorpComm: AI Labs had an eventful year! Looking ahead, what priorities does your Lab have in the exploration and application of AI and deep learning algorithms? What challenges are you looking to tackle this year?

Jean Bolot: Not surprisingly given the technology positions of InterDigital, our main focus is on developing AI-based advances for wireless and for video.

Much of our work on wireless is done with Jim Nolan's lab. For example, we are looking with Ghyslain Pelletier on innovations for 3GPP such as channel state estimation and compression using autoencoders, a type of neural network, and with Miki Beluri on beamforming. We are also investigating the use of transformers. I mentioned transformers like GPT-3 earlier, which have been developed for text and language processing, but we believe they can be powerful tools to analyze wireless signals.

On the video side, we are working with Lionel Oisel's lab on the next generation of video coding and compression tools. Specifically, the goal for the AI Lab is to develop a completely neural network-based codec for video.



Finally, the AI Lab is launching a new effort this year – again in sync with Jim Nolan's lab - around data services, to build a pipeline to ingest, process and use live (as opposed to synthetic or simulated) 5G data to train and optimize the neural network models we develop for wireless research.

CorpComm: One of your Lab’s major accomplishments was the introduction of CompareAI – the very first mobile app developed end-to-end in InterDigital’s Lab and the world’s first AI-enabled image compression app. In your words could you tell us about this pioneering app, what it revolutionizes, and who should download it?

Jean Bolot: We are very excited about the app. It is the very first iPhone app released by InterDigital and it is a great platform for users to experience our technology. In addition, it was very valuable for us to see the app’s development from scratch all the way to being published on the AppStore. Much thanks also to Olivier Le Quéré and the legal team who were critical in helping us navigate through the agreements and legal issues.

The app is unique because it is the first available implementation of a completely neural network-based compression for images. This is also the first time that these neural networks are enabled to run on a resource-limited device like a smartphone. This is important because most large neural networks run on big GPUs and CPUs in data centers and configuring them to work on commercial phones without draining the battery is still a challenge. Finally, the app lets users visually compare the quality of compressed images obtained with both neural network-based and with traditional techniques like JPEG or HEIC.


Next step for us is to release a deep video compression app later this year. But for now, please don’t be too harsh on these new AI-based techniques 12 This is still the beginning and just having them run on the phone is an achievement!

CorpComm: If you were to look into a crystal ball, where do you think AI and deep-learning algorithms will bring the greatest impact to our industries, and society at large?

Jean Bolot: Three decades ago, Mark Weiser coined the term "ubiquitous computing" to describe a world in which computers would be everywhere – in data centers but also door locks, watches, cars, smartphones of course and basically around our world today. I believe we need to prepare for "ubiquitous AI", namely a world in which all these computers have advanced AI capabilities. Ubiquitous AI raises many challenging issues of robustness, privacy, or energy use, but it also opens the door to boundless new opportunities. What AI can do now would have been considered magic 15 years ago. It's our turn now to invent the magic ahead.

CorpComm: Your department works tirelessly to make AI Algorithms smarter, and more predictive, to understand users and systems better. In an effort to better understand YOU, we’d like to offer a few random prompts for rapid word association, and why, to better get to know the man behind the AI.

First word is: HAL

Jean Bolot: ipHone + ALexa

CorpComm: Next is: Season?

Jean Bolot: 4 seasons. Vivaldi. My favorite composer.

CorpComm: Next word is: Samoa

Jean Bolot: Tropical island. Hawaii. Would love to be there now! 

CorpComm: What do you think when you hear the word: Michael?

Jean Bolot: Nothing special pops up in English but in French, Michel, I think of Mont St Michel. Amazing place.

CorpComm: And lastly, what do you associate with the word: resolution?

Jean Bolot: New year resolution. Failure. Except if only one. And grit.

CorpComm: Thank you Jean and thank you for letting us get to know you and learn more about the incredible work in the AI lab. We’re looking forward to these new developments and will encourage everyone to download the newest CompareAI app here.

On this edition of Getting To Know You InterDigital, Corporate Communications interviews Mike Cortino, InterDigital’s Head of Information Services, to learn more about the department, exciting new projects, and some of the questions keeping Mike busy as we all work from home.

Corporate Comms: Mike, you joined InterDigital this year as the Head of Information Services, at a time when our company, and the rest of the world, was making the transition to work from home. Throughout the journey, we have faced a plethora of challenges as people shifted to make their homes into working offices. Looking back on this year, what word or phrase would you use to describe your first couple of months with InterDigital?

Michael Cortino: I think unique is a great word to describe it. To add to that, I would say exciting because it was something new. Coming in to lead a function that really has the responsibility for enabling the work from home activity made it exciting and made it challenging. I think that's extremely unique, and I will say I was pretty fortunate to join a team that had already started working on the work from home environment. They started laying the foundation before I joined InterDigital so we are well underway, which was great.

CorpComm:  During our recent All Hands you outlined many projects that IS has begun and completed this year. It's clear that your team has been incredibly busy 😊. Could you offer us an overview of the main projects your team has been leading, and the success you've had so far?

Michael Cortino: Within the application space, there's a few key initiatives for us as a team. One is our data warehouse initiative, which is part of the digital transformation program we kicked off earlier this year. That' project’s really important for us as we move forward with analytics in the future and more robust reporting to support all of the functions. We have the application design in place, an environment stood up, and now we're just building out that environment so that we can flip the switch and move it into production, which will happen early next year.

Another initiative is one where we’re moving all of our policies and procedures to a new tool called ConvergePoint, which sits on top of SharePoint. We also made numerous improvements and enhancements in Microsoft D365 to support Finance.

In infrastructure, we migrated to a new data center in France, and implemented a new hyper-converged environment, both large scale initiatives. And we did all of that during COVID, which was pretty challenging, but the team stayed on it and got it done.

We also migrated from Skype to Teams, which was a big move as well. We upgraded many of our conference rooms to support Teams, and even though people weren't really going into offices, we were able to get approval to upgrade a number of those conference rooms throughout our facilities footprint.

Last, but certainly not least, we made some really big strides in the information security space. That's one thing I take a pretty keen interest in because if there's anything that's really going to impact us from a systems perspective as a company, it's bad actors armed with ransomware or phishing campaigns that bring down critical systems. So, we've been focused there and put together a pretty robust plan, inclusive of offense and defense initiatives.

We brought on a vendor to help us with brand protection. Anywhere InterDigital is mentioned in the ether, we get notified and have a vendor who watches over to prevent domain squatting and the like. We also have a number of tools to monitor the dark web and different areas for user IDs, so usernames and password combinations, which in conjunction with the password policy change to encourage a more sophisticated password, helps prevent hacking. And we of course have multifactor authentication, utilizing Duo for a second authentication to log in.

These are all things I think are big wins for us across the various domains of applications, infrastructure and information security – just to name a few.

CorpComm: This year has been one for the history books, without any year like it. Despite that, we were able to accomplish a lot of really wonderful things, given the headwinds that we faced. What would you say is the accomplishment you’re most proud of this year, perhaps something the company at large isn’t aware of?

Mike Cortino: I'm going to start with a broader answer and then hopefully narrow it down a bit. But one thing I would say helps in this unique environment that we're in is that InterDigital is a unique business. Because of that, and because our staff has a professional user base – all experts in their field, many highly educated people in the company – we were all able to migrate to this new way of working pretty seamlessly. That's not the experience that many companies faced, because there are a lot of companies whose user base has a wide spectrum of educational backgrounds, as well as the challenge of manufacturing environments. So, a lot of those companies struggled to make the transition.

We have a highly skilled user base across the company, and that put us in a pretty good position to make the transition. I'm most proud of that, and I'll add extremely fortunate. I joined right at the point where we began working remote, so, I didn't interact with anyone face to face. And thankfully, I did not have anyone in the company or executive team calling me saying, ‘Mike, we have a major issue’, or ‘My team isn’t able to do XYZ’.

I was pretty fortunate. My predecessor put in place a strategy of cloud first, and my hats off to them for doing that. I think that really positioned us well. Again, I was fortunate to land here and have a smooth transition and focus on the team, learn the business and just kind of get acclimated. So, I'm most proud of the work the team did leading up to this unique environment and the way they managed through it as the entire company transitioned to working remote.

CorpComm: Coming on the heels of this year and the variety of ways 2020, and the COVID pandemic, have influenced and reshaped our lives, what should we look for in 2021?

Mike Cortino: I mentioned at the All Hands the work we're doing around the Future of the Desktop. I think that's going to be pretty interesting for us at InterDigital. What we mean by that is, today we issue employees a laptop when they join the organization, and we have a phone policy where people bring their own phone. So, we are looking at what is it going to take for us to go to an environment that is completely “bring your own device”.

This would bring us to a position where we inform employees how to access all of the necessary applications through devices they purchase. We will develop, maintain, and support the access points. We will be working through the details in 2021 and look forward to rolling out the new program in 2022.

That's going to be a big game changer for us as a company. In our industry, research and innovation is so important, and a lot of engineers are accustomed to working on machines that are special or customized to the work they're doing. This would give our employees the flexibility to use a device of their choice and it allows us (IS) the ability to focus on what we do best, which is developing, maintaining, and supporting our InterDigital landscape.

Every company I've been with has talked about a BYOD, “Bring Your Own Device” strategy, but they never prioritized the effort and committed the resources. But now we are truly going to take it to the next level. And when we think about this from a recruitment perspective – the flexibility of our work policy and the flexibility to use a device you are comfortable with – packaged all together makes InterDigital even more of an attractive company.

CorpComm: Following the rebranding of Information Services as “IS”, we often use the phrase “IT IS what IT IS” to hearken to its IT origins. Today you’ve outlined the many possibilities for IS, so to continue in that spirit, we wanted to ask you a few fun “Either Or” questions. There is no wrong answer, only an honest one. 😊 So, first question is, Mac or PC?

Michael Cortino: I'm going to go PC because I don't own a Mac. Both my kids have Macs, but I don't own one. I don't have a preference, but I'm going to go PC.

CorpComm: Netflix or Xbox?

Michael Cortino: Netflix. I'm not a gamer, so Netflix.

CorpComm: Cooking at home or ordering in from your favorite restaurant?

Michael Cortino: Ordering in, which happens just about every day. We don't cook.

CorpComm: Favorite cuisine?

Michael Cortino: Oh, that's so tough. I just love food. Favorite, if I could only have one, I'm going to go with lobster ravioli in a vodka blush sauce.

CorpComm: Michael Jordan or Tom Brady?

Michael Cortino: Jordan. Yeah. Jordan.

CorpComm: And our last question, in the spirit of Thanksgiving, mashed potatoes or stuffing?

Michael Cortino: Mashed potatoes. But that's a trick question, because I like to mix them both. I like to take them and kind of slam them together. But mashed potatoes was the first thing that ran into my head, so, I'm going to go with that.

CorpComm: Thank you Mike and thank you for letting us get to know you and IS better. We are so looking forward to these new IS features and initiatives, stay tuned for updates on all the exciting happenings discussed within.

If you missed the 6G Symposium, check out our blog for a full overview of Day 1 highlights, a review of Day 2’s keynote speech by National Science Foundation's Dr. Thyaga Nandagopal, and recaps of the Symposium’s most thoughtful panels. Recordings of the sessions will be available soon.

While the 6G Symposium squared its focus on shaping a vision of 6G, the reality remains that the increasing deployment and commercialization of 5G will shift attention away from academic and research environments and towards production and implementation arenas. As we look to 6G, however, the academic and research community have an opportunity to take a fresh look and ask: "How can we develop and test new ecosystems for the generations beyond 5G?”

Moderated by Northeastern University Professor Abimanu Gosain, the panel discussion “Platforms for Experimental Research: Are we ready for 6G?” shared the perspectives of representatives from some of the most renowned research organizations on the opportunities and limitations for experimental exploration in 6G.

Julius Kusuma of Facebook's Connectivity Lab remarked how the last eight months of the COVID-19 pandemic brought connectivity issues to the forefront and highlighted the need for the industry to be both flexible and responsive. "This pandemic has provided us with a strong reminder that the world is diverse and the needs and use cases are diverse," he said. "For instance, who would have thought eight months ago that as consumers we'd be so concerned with upload speeds as we are today?"

As Vice Director of the National 6Genesis Flagship at the University of Oulu in Finland, Ari Pouttu spearheads laboratory research on wireless connectivity, devices and circuits, distributed computing, and a range of services and applications. Reflecting on the University’s body of research and looking ahead, he remarked that the research community must "join forces with stakeholders from all different verticals to take into account KPIs, use cases and methodologies to develop new thinking beyond just technology and productivity."

Vertical use cases are certainly a research specialty at North Carolina State University, where Professor Ismail Guvenc's team conducts its research. "We are researching Unmanned Aerial Vehicle Traffic Management (UTM) systems in conjunction with a NASA platform for drone air traffic control," he shared. "It's a great platform for a variety of use cases including wireless hotspots, agriculture, public safety, package delivery and more." He mentioned that NASA is also working on advanced air mobility systems for aircraft that operate at higher altitudes than drones because connectivity is patchy in the skies. He shared other verticals where testbeds are being developed, including smart buildings/smart cities, rural connectivity, AR/VR and several others across a range of indoor, outdoor, urban, suburban and rural environments.

From the perspective of a wireless operator, Parallel Wireless CEO Steve Papa offered a somewhat controversial perspective — "5G is the last of the monolithic pervasive, homogeneous G's." He added, "up until now, the network was needed by pretty much everyone in the same way. That's all changing now." While his comments may seem controversial on the surface, they point to a concrete reality: wireless networks are no longer built to cater to a single dominant use case. The development process and testing and research requirements for some use cases will likely progress along separate timelines now, posing an interesting new environment for research and testing organizations.

To recap the key take-aways and most thought-provoking presentations from the 6G Symposium, please join us for a 6G Symposium Sync Up webinar on Thursday, November 5 at 1:00 p.m. ET, hosted with Fierce Wireless. Symposium organizers Doug Castor from InterDigital and Tommaso Melodia from Northeastern University will join industry experts to digest and make sense of the event’s varying perspectives on the 6G roadmap, the role of AI and Machine Learning in 6G networks, spectrum sharing approaches, public-private research partnerships, and much more.

If you missed the 6G Symposium, check out our blog for a full overview of Day 1 highlights, a review of Day 2’s keynote speech by National Science Foundation's Dr. Thyaga Nandagopal and fireside chat with NIST Director Dr. Walter G. Copan, and recaps of the Symposium’s most thoughtful panels. Recordings of the sessions will be available soon.

The second day of the 6G Symposium continued the discussion around the challenges posed by spectrum, but with a specific focus on spectrum sharing. The panel's moderator, Monica Paolini, founder and president of wireless consulting firm Senza Fili, began the session with a baseline question for all panelists: What is the best way to share spectrum efficiently that brings everyone on board?

5G is currently being rolled out and delivering 1.5 GBps in certain cities in the U.S., a country that leads the world in high-band spectrum allocation. "When we talk about spectrum sharing, we need to talk about adjacent channel users too, not just co-channel users," said FCC CTO Monisha Ghosh. She illustrated this point by addressing the passive users in higher bands like weather satellites as well. "In mid-bands, around 8-10 GHz and below, where it's still best for wide area cellular use, the picture is different,” she added. “There it's more about sharing with incumbents. And unlicensed services have to protect primary users."

The 6G, or the “Next G” will face many of the same issues as 5G. Ghosh pointed out that with the convergence and proliferation of unlicensed spectrum usage for cellular, the hope is that industry can begin designing systems that enable those running on licensed and unlicensed spectrum to work together. In short, it is clear that 6G will require better spectrum sharing modalities than we have today.

To punctuate this discussion, the panelists discussed the rollout of the CBRS system in the 3.5 GHz band earlier this year. This band had previously been allocated exclusively to the U.S. Department of Defense to be used for radar systems, but is now being shared with commercial systems. This shared model system has been operational since January 2020. Panelists indicated that the system is exceeding expectations. "There have been no interference complaints so far," said Andrew Clegg, Spectrum Engineering Lead for Google. "We are due for some innovation in the propagation model world," he added, describing that the propagation models for CBRS date back to the 1960s. "That's closer to Marconi than it is to today." Google, he said, is aiding this research by using its massive database of geodata to build new propagation models.

Echoing the call for propagation model research was Sheryl Genco, director of NTIA's Institute for Telecommunications Sciences (ITS). "Our data science group is just beginning to take a whole nation approach to build a propagation model for the whole world," she said. "We are also looking toward real-time spectrum management, which could really help prevent interference to incumbents." She encouraged industry participation in this research effort, reminding audiences that NTIA has an open data policy and open use policy, meaning their propagation models are open and available for anyone to use.

Tom Rondeau, Program Manager for DARPA, offered the Department of Defense perspective on spectrum sharing. "Maxwell's equations haven't changed, but the way we interact with them has evolved," he said. "We don't just share spectrum; we share the knowledge of how we use it." Rondeau described how DARPA is doing advanced research around phased arrays, spread spectrum, and software defined radio systems. The biggest challenges, he says, are often around computational power. Network slicing is one way they have found to help reduce that computational power requirement.

Simply put, 6G is about significantly increasing performance, in all aspects, over 5G. Masoud Olfat, Senior Director of Technology Development for Federated Wireless, discussed that the overall goal is to make spectrum sharing more efficient, and to discover new ways to exploit spectrum sharing. "We are looking at open RAN, computational edge networks, network slicing models and NFV," he said. "We need to learn how we can use spectrum sharing to improve overall performance of the wireless network and people's lives."

If you missed the 6G Symposium, check out our blog for a full overview of Day 1 highlights, a review of Day 2’s keynote speech by National Science Foundation's Dr. Thyaga Nandagopal and fireside chat with NIST Director Dr. Walter G. Copan, and recaps of the Symposium’s most thoughtful panels. Recordings of the sessions will be available soon.

The second day of the Symposium explored some of the challenges facing the true realization of 6G’s potential, namely the limitations of spectrum.

As wireless data traffic grows exponentially, the question remains: how will we support it? This foundational question provided the framework to begin the panel “Conquering the Spectrum” on Day 2 of the 6G Symposium, moderated by Northeastern University Associate Professor Josep Jornet.

The panel offered a timely discussion to address many of the questions raised during Dr. Nandagopal’s keynote, namely “where will 6G fit in the radio spectrum?” Upcoming 3GPP Release 17 is expected to extend 5G up to roughly 71 GHz, but the most existing radio spectrum lies below 95GHz. It is widely understood that the industry must undertake much innovation to develop use cases and technologies that allow radio communications in the Terahertz bands. There was much discussion about the frequency ranges, which are expected to range between 60 GHz all the way to 3 THz, but less has been said about use cases it will enable.

Discussion moderator Jornet offered a few suggestions, including Terabit wireless backhaul, inter-satellite and space networks, or even potentially for sensing applications like non-damaging imaging and high-resolution radar. Overall, he encouraged the panelists to use the session to answer questions about devices, test beds and materials, as well as propagation and channel modeling. The conversation also addressed questions around signal processing, networking, policy, regulation, and standardization.

Gerhard Schoenthal, COO of Virginia Diodes, Inc., outlined the very real challenges of spectrum availability. "Wireless products have to cover wide swatch of spectrum," he said, adding that since materials like iridium phosphide are not as well developed as other semiconductor materials, the products face a materials challenge at higher frequencies.

Signal propagation was also highlighted as a major challenge by Thomas Kurner, professor at TU Braunschweig. "Particularly in indoor environments, small objects play a role in propagation, reflection and scattering," said Kurner. "Even something as simple as wallpaper over a concrete wall can cause multiple reflections at higher frequencies." He went on to say that while these problems currently exist in the millimeter Wave (mmW) bands, they will become more pronounced at the THz levels, therefore further innovation is needed before such solutions reach the mainstream.

Despite these challenges, early 5G mmW deployments are underway, and are achieving high peak data rates greater than 1 GBps. However, coverage is still intermittent for now. The primary challenges with implementing mmW are directionality, blockage, and range. In addition, there will be greater challenges with device power consumption, high network density and an apparent lack of clear use cases for the technology. "In upper mmW bands, like around 140GHz, there are some savings possible, but power may still be prohibitive because these devices pull a lot of wattage," said Sundeep Rangan, Professor at NYU, pointing toward some potential use cases. "At around 140GHz there may be a good use case to use this band for fronthaul and drones/UAVs, or possibly in point-to-point backhaul links, such as line of sight MIMO at ranges of up to around 1.5 kilometers."

Offering another academic perspective was Edward Knightly, Professor at Rice University, who described exciting research around high frequency beam steering. He described that, because different frequencies emit at different angles, his team has seen the potential for beam steering through adjustments to the antenna. He also discussed how new sensing capabilities could be made possible at the THz level, which could enable high resolution millimeter scale radar with a single antenna. There are also security implications of very narrow beams too – narrow beams emitted at different frequencies can thwart eavesdroppers and side-channel attacks, which would unlock new security capabilities.

There are regulatory and policy considerations for spectrum as well. Relative to other technologies, wireless is a highly regulated industry. Policymakers and regulators frequently ask questions like "how much spectrum does 6G need, and how much is available?" Agencies and government institutions will be looking for more concrete numbers than the industry can currently provide. This issue came up earlier this year with concerns regarding potential 5G interference with NOAA's weather forecasting satellites, which are passive users of some of the adjacent spectrum allocated for 5G. "A study is underway about minimizing interference and enabling a win-win sharing of spectrum," said Mike Marcus, former FCC spectrum policy lead. "Weather satellites will be protected," he added, reminding the audience that the ITU rules on passive bands will not change until 2027, at the earliest.

This riveting discussion was underscored by an interesting consensus among panelists. All agreed that, while there is uncertainly today about where exactly the eventual 6G spectrum will be, key stakeholders will work together with a shared vision to enable the exciting new possibilities in these high frequency bands. Knightly concluded by saying, "if you have devices that can give you millimeter-scale resolution sensing of the world around you, the sky's the limit in terms of what's possible."

With a successful kickoff to the inaugural 6G Symposium, we continued the momentum on Day 2. On Wednesday, a diverse collection of panelists from across industry, academia and government took a deeper look into the many technical and visionary issues facing 6G’s, and the industry at large’s, future.

If you missed Day 1 of the Symposium, a recap of the full day is available here, and recordings of the sessions will be made available soon.

Day 2 began with a brief synopsis of the Symposium’s key takeaways by InterDigital's Doug Castor and Northeastern University's Tommaso Melodia, highlighting some of the hundreds of questions received from the more than 4500 event registrants. The organizers then turned the stage to Dr. Thyaga Nandagopal, Deputy Division Director for the National Science Foundation, to deliver the day's keynote address.

Keynote Session: Wireless Spectrum for NextG

Dr. Nandagopal's remarks, "Wireless Spectrum for NextG" began the second day of the 6G Symposium on a more contrarian note: he quickly introduced the concept he calls "NextG" – as opposed to 6G – which he says is after 5G because "by the time people switch to the next generation, that's when the real explosion of the growth and the killer apps takes place."

He gave a preview of one of the day's main themes – spectrum – highlighting that while we know 5G will use spectrum up to the 50 GHz band, the “NextG” will probably begin above 50 GHz. Looking ahead to the upper limit of that spectrum for 6G/NextG, it remains unclear where that upper limit is. This lack of clarity he described provided a launching pad for the fascinating perspectives shared by the panelists throughout the day.

Dr. Nandagopal went on to share that historically in wireless, the computational power curve has been accelerating faster than the availability of spectrum. This reality has brought significant challenges for the industry, as well as dramatic opportunities for innovation, particularly in the areas of spectral efficiency. As the industry moves toward higher frequency bands and greater availability of spectrum, this raises new questions. Historically, higher frequencies meant faster and better technology, and certainly more network capacity, and smaller antennas meant more compact devices. "While these were historically true," said Nandagopal, highlighting major spectrum reallocations dating back as far as the 1940s in the U.S., "many of these things will not be true in the sub-6GHz millimeter wave bands used in 5G."

The proliferation of radio technologies means that spectrum is scarce. Technology is one way the industry has traditionally addressed that scarcity, because moving incumbent users to different frequencies is very hard and takes tremendous time and resources. Furthermore, it takes time to try new methods of spectrum allocation. But, just as with any innovation, where there's a will there's a way.

Spectrally-speaking, there is currently a bit of "beachfront" spectrum available, meaning the most desirable, and also most scarce, spectrum in the 600MHz to 6GHz range. Nandagopal expanded the beach analogy to say that "if we dredge some sand and expand the beach, we can move into the 6-7GHz bands, then add spectrum up to the 10GHz band." This kind of innovation, especially if we further expand the range into the 20GHz band, will allow the industry to reap the benefits of mid-band usage and high spectral efficiencies. From there, with another 4GHz of spectrum, we can see better peak rates and more efficiency from massive MIMO. At even higher frequencies – reaching the mmWave range from 30 to 300 GHz – there would be enormous bandwidth gains that we don't yet know how to use. These high frequencies present a truly greenfield opportunity. In the Terahertz range, above 300GHz up to 3THz, we’ll inevitably see new challenges emerge and power will present an enormous challenge, but over time breakthroughs will happen.

Looking historically, Nandagopal noted that the current model of using shared spectrum in tandem with unlicensed spectrum is essentially the same model the United States has used, more or less unchanged, since the early 1990s. Through that historical lens, he implored the audience to look at a wide-open future.

"Imagine if we had a set of unlicensed and unrestricted frequencies spanning low, mid and high bands. Imagine a world where devices can self-identify the desired swath of frequencies and power levels they need to get their data transmitted," he illustrated, going on to explain that AI and machine learning would help us achieve such a vision, and the significant government and private investment currently underway in this exciting arena.

Dr. Nandagopal received the day’s first question about quantum computing, responding that he felt quantum computing was indeed coming, but not as soon as many might have hoped. He cautioned that quantum computing was still at least 10 years, if not 15 years, away from full realization, and probably 25-30 years away from reaching widespread commercial use. More encouragingly, he shared that while quantum computing would help solve complex problems of the future, there remain “low hanging fruit” challenges for the wireless industry to address in the near term while quantum matures.

Dr. Nandagopal concluded his remarks with a simple statement: "There's more than enough spectrum to go around, but there's a need to innovate, and to leverage R&D." We agree and look forward to many years of exciting research and development on the next generations of wireless technology.

Fireside Chat with NIST Director Dr. Walter D. Copan

To share the U.S. government perspective on the path and pursuit to excellence in science, technology, and research, NIST Director and Under Secretary of Commerce for Standards and Technology Dr. Walter Copan engaged in a fireside chat on the U.S. technology roadmap, moderated by Northeastern University Senior Vice Provost for Research David Luzzi.

Dr. Copan began the discussion by sharing that standards development is a priority for NIST. "Our focus is on American innovation and to advance industrial competitiveness by advancing measurement science, standards, and technology in ways that enhance economic security and improve our quality of life," he said. The organization places a significant focus on advanced communications technology and standards for 5G and beyond, with the goal of strengthening America's global competitive position. This message closely follows those shared during Day 1’s fireside chat with FCC Chairman Ajit Pai.

Professor Luzzi began the conversation by asking about NIST's position on, and involvement in, disaster resilience, an area where the wireless industry has shown some need for improvement. Dr. Copan described how the agency is applying its experience in disaster resilience, with a focus on standards, the future of supply chain integrity, and looking at lessons learned. "We seek to learn from failure points," he said. "From there we work on building recovery models."

The conversation then returned to one of the day’s hottest topics: spectrum sharing. Dr. Copan noted, "we are very excited about work that's come out of NASCTN - the National Advanced Spectrum and Communications Test Network," adding that "this work has provided tools for the co-existence of radar and 5G mmW models, and related use cases." He went on to describe how the research and standards work in the mid-band is essential, and how CBRS use cases have provided important validated datasets.

Dr. Copan reminded audiences that the NIST encourages public participation, noting that their datasets are available for research purposes. "Some data we have needs to be anonymized for privacy purposes, but generally our data is available," Dr. Copan said. "Members of the alliance get full benefit, but at a high level all of that information is broadly available, and NASCTN provides a rich data source as well."

To close out the day’s discussions, the focused shifted from considerations for future research to our current reality. The United States has had a relative slow start in 5G, and has a new opportunity to overcome that hurdle and improve the U.S.’s current leadership position 5G. Dr. Copan outlined efforts on the 5G deployment road map, highlighting the transparent ways the federal government is working on the roadmap. "Many of the lessons have been taken to heart," Dr. Copan said. "ATIS has announced a 6G alliance, and that should be a strong opportunity as well.” He added that NIST supported the initiative, of which InterDigital is a Founding Member. One outgrowth of this work, he added, is to encourage stakeholders to look at the future of U.S. innovation and the legislative and policy changes it can enable. He suggested that policymakers could incentivize work by the private sector and encourage collaborative research and innovation, an area where the U.S. has lagged behind its global counterparts at times in the past. Dr. Copan ended on the encouraging note that, on the whole, the NIST is looking to incentivize research and innovation and other strategies in ways on par with, and exceeding, the country’s peers.

Check back later this week for more highlights and new updates about the 6G Symposium.

October 20, 2020 / Posted By: InterDigital Comms

The kickoff of the first annual 6G Symposium was a huge success, with more than 4000 participants from around the globe registering to hear insights and perspectives on the 6G vision, emerging 6G technologies, and the role of AI in wireless networks. Through panels and presentations, we learned how foundational technologies like blockchain, AI, network coding, and THz may drive a fresh look at what’s optimal for 6G architectures and spectrum sharing policies.

For the first time ever, InterDigital joined ranks with the Institute of Wireless Internet of Things at Northeastern University to kick off the first-of-its-kind 6G Symposium, a two day virtual event dedicated to shaping a clear vision for 6G.

Taking place as we’re beginning to see the earliest phases of commercial 5G, the 6G Symposium kicked off with the important level-setting question: "What’s next?"

The Symposium is dedicated to looking ahead to the next 10 years of research and standard setting to explore the potential 6G holds, what it may become, and the new opportunities it might unlock. There’s a general understanding among stakeholders in this field that 6G development takes time, resources, and a commitment to global cooperation to develop a successful wireless ecosystem. Day 1 of the Symposium helped us to better shape the path ahead.

So what exactly will 6G look like? We know 6G will enable faster delivery speeds, but it will also bring changes to the wireless interface and architecture, introduce new radio models, and support a massive proliferation of devices. Fun Fact: early estimates suggest that by 2030, there will be 500 billion devices across a global human population of roughly 8 billion. That's more than 60 devices for every human on earth. To support this future and bring 6G to the forefront, players from across the wireless ecosystem must collaborate to find the best solutions for this exciting and impending future.

Keynote: AT&T’s Mazin Gilbert

Mazin Gilbert, AT&T VP of Network Analytics and Automation, opened Day 1 of the Symposium with a visionary view of the future beyond 5G. During his keynote address, Gilbert noted that the COVID-19 pandemic has altered people’s primary means of interactions, and the timing of the recent 5G commercialization is somewhat fortuitous because every new generation of wireless was built to adapt to a new way of life. While 5G remains a “mobile” technology, it also has natural characteristics that make it well suited for a world where we are considerably less mobile than before. As we look ahead to 6G, it’s reasonable to assume that we may need very different networks and systems to fulfill our new ways of life. In the future, networks will need sophisticated infusions of AI/ML and certain levels of autonomy to enable them to self-organize. Our networks will need to evolve with our needs, and while 5G networks are more decentralized than their earlier counterparts, future 6G networks will take decentralization to new levels.

In a 6G world, new devices like XR glasses will enable new visual experiences through things like browsing the news, providing real-time performance updates during a morning workout, or help us locate a friend, and the gift shop, at a crowded sporting event. Cars will have sophisticated sensors and intelligence, and live events and concerts will enter our living rooms in exciting and immersive ways. And for those working from home, interactive video conferencing will move beyond two-dimensions and become more immersive.

Throughout his keynote, AT&T’s Gilbert described modern technology’s disruptions in agriculture and industry, including the use of robotics and video surveillance to pinpoint the precise time for harvest and the increasing automation of factories and dynamism of industrial robots. To support these changes, networks will need to become more open and disaggregated. The network will no longer be a closed box, but instead opened through APIs, and enable personalized experience not possible today. Due to the proliferation of the mobile edge cloud, each person’s computing power and storage will follow more closely wherever they go, and network slices will enable and guarantee service for particular use cases.

While exciting, the 6G vision brings significant research challenges as well. To enable the experiences we envision, players from across the ecosystem need to collaborate to optimize spectrum sharing and efficiency, develop new technologies and adaptive learning algorithms, anticipate and mitigate cybersecurity attacks, and address the vital topics of battery life and energy efficiency. In the future, networks will need to be self-organizing to ensure traffic is dynamically optimized across intensely densified deployments.

6G, the next generation of wireless, is still largely a vision. But even today we know that once it takes shape it will open a world of possibility and a wealth of opportunity. As the day continued, the Symposium panelists and speakers explored how.

Panel 1: Shaping Up 6G: Drivers, Use-Cases and KPI Requirements

In many technology visioning exercises, KPIs and driving factors are often determined by technical elements and technology solutions; however, this panel looked beyond those issues to address real world social and economic indicators, many of which have generational consequence, like the industry's impact on climate change and global poverty. Today, most companies recognize that sustainability isn't just a feel-good trend: sustainability, and sustainability in wireless, is good business.

The wireless industry is, for example, approaching the end of the smartphone base station era and entering into an era where devices, only some of which are consumer handsets, connect to a variety of smart surfaces. Panelist Dr. John Smee, Vice President of Engineering at Qualcomm, suggested that from a research standpoint we are halfway through the 5G lifecycle, even though 5G commercialization is beginning in earnest this year. He noted that 6G will bring things like data-driven system design, where we use AI to help design the air interface and help optimize system design and performance.

Samsung SVP and Head of the Advanced Communications Research Center Sunghyun Choi described how new form factors such as XR glasses, VR headsets and hologram devices will be built with low power consumption in mind, while running on networks that use advanced AI and machine learning to optimize energy consumption, among other things.

Virginia Tech professor Walid Saad noted that next generation networks will be more capable of addressing a range of limitations in reliability, mobility and coverage, especially in rural areas, to bring the world more consistent levels of service and availability. Karri Kuoppomaki, Vice President of Technology Development and Strategy at T-Mobile, agreed, sharing that "6G will play critical role in enhancing mobile broadband."

Another interesting driver of 6G identified by the panel is the trend toward standardization of non-terrestrial networks (NTNs), which are beginning to be included in 3GPP Release 17 for 5G, according to Ericsson’s Director of Industry Engagement and Research Afif Ossrrian. NTNs are communications networks that exist in areas not tied directly to land – networks between aircraft, on oceangoing ships, and even in space.

Throughout the discussion, panelists, and industry at large, share a consensus that radio access networks are a major consumer of energy. This panel explored how radio access networks can become more efficient by becoming smarter through the use of AI or with the use of technologies that put certain devices in low power states when they aren’t needed/in use. This method can both reduce network traffic and save considerable power, even in massively dense IoT networks, while the use of a shared spectrum will augment the efficiency of radio access networks.

Panel 2: Understanding the 6G Tech Landscape

Since the beginning of wireless, each new generation has introduced a key technology that enabled its growth. The first generation of cellular -- known as 1G -- brought voice communications, 2G brought data, 3G brought broadband, and 4G brought mobile video. We have yet to determine the "killer app" for 5G, but it utilizes the well-known "triangle of technologies" model to determine new 5G applications. Each corner of the triangle represents one technology ideal and includes: enhanced mobile broadband (eMBB), ultra-reliable low latency communications (URLLC), and massive machine type communications (mMTC). While it is too soon to definitively determine the technologies 6G will deliver, the panelists shared their views on some emerging trends.

Prabhakar Chitrapu, Chair of the Small Cell Forum, outlined the technologies, deployments and services that come along with each wireless generation. As we move from one generational era to the next, the deployments and services from the prior generation must first mature, then new technologies are introduced, after which the deployments and services mature again, and the cycle repeats.

According to Takehiro Nakamura, SVP and General Manager of NTT DoCoMo, the 6G era will be a time of extremes: extreme high throughput, extreme coverage, extreme low energy and low cost, extreme low latency, extreme high reliability, and extreme massive connectivity. These extremes may become the defining feature of 6G, moreso than any single defining technology. In addition, he shared that 6G may be defined by new network topologies that emphasize advancements in areas like device-to-device communications and the addition of NTNs.

Following the trend of 5G, experts expect 6G to continue the evolution toward software-defined networking. As industry moves away from proprietary eNodeB and closed, telephony-based core architecture towards a distributed, user-defined, cloud and commodity hardware-based model in 5G, these evolutions and focus on open architecture and open standards will likely continue. "The sea change here is de-coupling the technology from the architecture," said Larry Peterson, CTO of the Open Network Foundation.

When it comes to spectrum, 6G is positioned to find ways to exploit new spectrum and more aggressively utilize the spectrum that is available. Quantum computing will play a role in 6G as well, albeit a potentially paradoxical one. On the one hand, quantum encryption, storage, and possibly even blockchain technology will help make aspects of 6G a reality. On the other, quantum can also pose new cybersecurity threats, possibly even before it becomes an asset.

Lastly, the panel was somewhat divided when determining which standard will introduce 6G, but most panelists agree that Release 19 or 20 will be the earliest true 6G standard.

Panel 3: The Role of AI/ML in 6G Wireless Systems

AI and machine learning are the hottest topics in wireless today, and it is a topic that grows in interest, and complexity, as we move beyond 5G. During the “Role of AI/ML in 6G Wireless Systems” panel, DeepSig CTO Tim O'Shea described the evolution by saying, "ML & AI technology is behind all of these: device density, spectral and spatial efficiency and optimization, data driven AI applications, reliability and QoS, bandwidth, latency, energy efficiency and ultra-massive and distributed MIMO." In next generation networks, complex AI/ML algorithms will help maximize hardware efficiency and resources for countless high throughput devices and significantly improve capacity between different network components.

When exploring the use of AI in radio access networks, John Davies, Program Manager at DARPA, shared that while so-called "cognitive radio" is not a new idea, and the early research is encouraging (though questions remain whether the technology exists to make it worthwhile in the near term.) Certain aspects of the new technology require further study, such as how to ensure spectrum sharing is handled fairly and in predictable ways. Davies noted that, "it will be a challenge to figure out how to manage the oversight of these radios." As a result, industry may need new rules, and even new algorithms and data sets, to address that uncertainty.

InterDigital Engineer John Kaewell highlighted that ML will be "a powerful tool in the 6G system designer's toolbox." He described how ML can provide impressive performance gains over traditional systems design approaches. He also noted that for ML to play a major role in 6G wireless, we will need several pieces in preparation, including large and open datasets, advancements in deep learning models and training methods, and ready availability of high computational power.

While the expert panelists shared a diverse array of viewpoints, all agreed on one topic: Industry can't let go of domain knowledge. Despite the allure of these intelligent networks, industry can't just turn every function over to AL/machine learning. To be effective and manageable, AL/ML networks must be built on strong foundations of human knowledge and human oversight – machine learning will surely help with network functions too complex for human management. And that reality will unlock tremendous potential and efficiency.

Fireside Chat with FCC Chairman Ajit Pai

Day 1 of the Symposium rounded out with an engaging fireside chat between InterDigital CEO Bill Merritt and FCC Chairman Ajit Pai.

In a wide-ranging and frank discussion, the two discussed the ways the FCC's role has changed in recent years and how the Chairman expects it, and its responsibilities, to evolve as the industry moves toward 6G. Pai praised the private sector for stepping up to deliver on the promise of 5G, and particularly highlighted the United States' leadership role in the global standards development.

Throughout the discussion, the pair discussed topics as specific to the industry as precision agriculture and as broad as the importance of standardization. In a lively discussion on spectrum, the Chairman highlighted the FCC's somewhat diplomatic role in helping carriers work together to solve spectrum availability challenges in recent years.

A pressing question perhaps on everyone's mind was the influence of China in the wireless ecosystem. The Chairman explained how the FCC's position toward companies like Huawei and ZTE was not about singling out those companies, but instead establishing a risk-based framework to protect the interests of the American people. Moreover, he highlighted that issues of security and privacy, and those like rural broadband access, were not partisan issues, but instead American issues in need of a unified solution.

The fireside chat ended the first day of the 6G Symposium on a very positive note, ending with a reminder of the importance of open standards while encouraging innovation and developing new technology solutions to emerging problems in the next evolution of wireless – 5G, 6G, and beyond.

Join us for Day 2 of the 6G Symposium for a deeper dive into spectrum sharing, experimental research, and all things 6G. Please visit www.6gsymposium.com for more information.

Of course, not many companies in the tech space have the history that InterDigital does: we were founded one year after Intel introduced the first microprocessor, and the same year as Wang introduced the first word processor and that Pong was launched. We thought it would be great if we dug into the vaults, pulled together some of our material, and created a series of short videos on some of the most important moments in our history as a company. The result is available at https://www.interdigital.com/history/

We take pride in the fact that many of our shareholders, partners, alumni and others have a long history of association with the company, many dating back to our International Mobile Machines (IMM) days. For those who’ve been part of the extended InterDigital family for a long time, I hope you’ll enjoy the comments and memories of Gary Lomp, Fatih Ozloturk, Brian Kiernan, and others whose time with the company has marked our history, as well as footage of the first Ultraphone deployments, the Reagan Ranch, the Avianca crash, and other oddball moments that have marked our first 45 years.

As many of you know, two years ago we changed to a fully virtual Annual Shareholder Meeting format, in keeping with our role as a technology leader. Some of you will recall that the Q&A portion of last year’s meeting was cut short by a storm-driven power failure, but we think the odds of that happening twice in a row, coinciding with our annual meeting date and time, are pretty low. So looking forward to seeing you next week!

The virtual format comes with some new meeting registration procedures, so we’ve posted a document that clearly spells out what you need to do to attend online. The press release went out this morning, and the document can be viewed here.  

Please make sure you read it, and factor in some time on the day of the event to register correctly.  Think of it the same way you’d attend in person, where you’d leave in plenty of time to make it in case of traffic and would factor in time to register at the desk. Online registration opens at 10:30 a.m. Eastern Time on June 14.  The instructions are simple, and there are resources (including a toll-free number) available if you’re having any issues.  

Thanks, and looking forward to your participation.

Just a quick note to our valued shareholders that additional questions and answers from the Annual Shareholder Meeting have been posted, and can be viewed here. Our apologies for the mishap with the power failure – everything we could control was going great, but we can’t control the weather!
 
When the meeting ended there were three questions by e-mail that had not been answered and a further five questions submitted via the online platform remaining in the queue, with some overlap between the questions as is invariably the case. We’ve also responded to a lengthy comment on why we hold a virtual shareholder meeting.
 
Thank you all for attending this year – with over 90 online attendees it was a success, but even we can’t do much about confirmed tornadoes!

The oneTRANSPORT initiative in the UK has been an enormous success, highlighting the tremendous role that breaking down data silos and exposing new sources of data can play in improving services for consumers… and driving revenue for public authorities.

It’s also been getting a lot of attention in the technology media. After an excellent article last week in ComputerWeekly, this time it’s Computer Business Review having a look at the project, with a very interesting angle: how cities and public authorities can use IoT technology (in this case, InterDigital’s oneMPOWER™ platform) to monetize their data at a time of ongoing public spending cutbacks. “Projects such as oneTRANSPORT show that councils have important assets already available that might help them ease the pain of spending cuts – and technology might be the way to unlock them,” says CBR’s Alex Sword.

March 23, 2015 / IoT, M2M, IP, oneM2M / Posted By: InterDigital Comms

The Internet of Things (IoT) is one of the most important areas of research for InterDigital, for a variety of reasons. For our technologists, we understand that it’s a force that will in all likelihood fundamentally alter the way the world operates, much like the advent of large-scale business computing or the Internet. For our investors, we often highlight that IoT is one of the next big opportunities that the company is working to capitalize on, through a variety of approaches including our Convida Wireless joint venture, our ONEMPOWER M2M service delivery platform, and wot.io, our startup focused on IoT data management.

So although it’s still early days for IoT, we were happy to see InterDigital included in a list of IoT market leaders when it comes to intellectual property. In a blog entry yesterday, Boston-based TechIPm, LLC, a professional research and consulting company specializing in technology and intellectual property mining and management, ranked InterDigital third in its “M2M for IoT Innovation Ranking,” just behind LG and Ericsson and ahead of Samsung, ETRI and Qualcomm, among others.

The ranking underscores the pioneering development and standardization work that InterDigital has done in IoT, including helping to drive the ETSI standard that is now a part of the OneM2M effort. That work has also been captured in a solution, the ONEMPOWER M2M service delivery platform, which was highlighted at Mobile World Congress in Barcelona.

It should be noted, InterDigital does not vouch for the accuracy of third-party research or the methodologies such researchers employ – TechIPm’s conclusions are their own. Still, it’s nice to be noticed!

February 1, 2015 / bylaws / Posted By: InterDigital Comms

Today, our company announced that our board of directors had approved some amendments to our bylaws, in the form of an 8-K. Among the changes there’s one that, as head of investor relations, I’d like to highlight: we adjusted our bylaws to provide InterDigital with the ability to hold a virtual annual shareholder meeting. Virtual annual meetings provide shareholders with the ability not only to hear the proceedings and ask questions online, but also to vote real-time.  Annual meetings can be fully virtual or hybrid, combining an in-person physical meeting with an online virtual component.

Fully virtual annual meetings have been progressing in terms of adoption recently – according to Broadridge, one of the leading virtual annual meeting technology providers, the number of companies holding fully virtual annual shareholder meetings almost doubled from 2012 to 2014. While it’s still certainly a minority of public companies, the trend is clear. And, as a company whose brand is intertwined with advanced tech R&D and the future of communications technology, we feel like we should have the flexibility to be on that leading edge.

At InterDigital, part of our analysis about whether a fully virtual annual meeting makes sense or not is rooted in our recent history. In 2013, we nudged virtual participation ahead by taking questions by e-mail and providing an audio webcast. Last year, we went a step further, providing a full HD video webcast and encouraging online participation (but not real-time voting). The results were significant: although the event was still optimized for in-person participation, we had only a handful of shareholders in attendance… but more than 70 online.

So the bylaw change is motivated by something very simple: the desire to have the ability to optimize the annual meeting for the vast majority of people who attend it, and to make it easier and more enjoyable for as many shareholders as possible to fully participate. 

We have not yet decided whether we will hold a fully virtual annual meeting in 2015, but we wanted to make the bylaw change now so that we have the option, either now or in the future.

As always, I’d be happy to take specific feedback at patrick.vandewille@interdigital.com.

January 5, 2015 / CES / Posted By: InterDigital Comms


The topic of patent reform and intellectual property has been a hot one in recent years, and the wireless and technology industries have focused tremendous amounts of attention on it. The Consumer Electronics Association, of which InterDigital is a member, chose this year to host a panel on the topic and reached out to our President and Chief Executive Officer, Bill Merritt. As Bill said prior to the panel, “When you look at the topic it seems like everyone is fighting, but when you take the discussion to a high enough level, everyone agrees on what we need: quality patents, the elimination of bad actors, and responsible industry practices.”

The extremely well-attended session was hosted by Michael Petricone, (@mpetricone, Senior Vice President of Government Affairs for the Consumer Electronics Association). Bill Merritt was joined on the panel by Lee Cheng (@leecheng and Chief Legal Officer of NewEgg Inc.), Sally Washlow (President of Cobra Electronics), Laurie Self (VP if Government Affairs at Qualcomm Inc.), and Katie McAuliffe of Digital Liberty, a Washington-based lobby group.

As Michael Petricone said in his introduction, “America has always been characterized by a great patent system, and when you walk the halls of this show you see concrete evidence of that.” He described what he characterized as “everyone’s goal” of balancing incentive to innovation with reigning in practices that can be detrimental to companies.

“Our company wouldn’t exist without a strong patent system – half the products that you see out in the show wouldn’t exist without a strong patent system,” said Merritt, who further underlined that the correct way forward lay in “striking a balance” between innovation and the interests of consumers, businesses and the country. Laurie Self of Qualcomm highlighted the importance of intellectual property protection in the wireless industry. She mentioned that “many of the investments that my company and InterDigital make in research and development are for technologies that may not be in the market for 5 years, or ten years, or ever. The only way we can make those bets is with the protection of the patent system.”

Lee Cheng characterized his stance as defining bad actors via “actions-based” definitions, rather than asserting entity-based descriptions. He defined a two-pronged test for abusive behavior: that the patent being asserted is a bad patent, that probably shouldn’t have been granted; and secondly that the behavior is designed to take advantage of the legal system to extract compensation that is higher than the value of the patent. Sally Washlow highlighted the contrast between innovation and abusive behavior very succinctly: “We’re a company, we develop technology and have patents and we have nothing against licensing, but often when we receive letters we feel like we’re being extorted.”

Merritt highlighted the agreement on the panel, and underscored that a number of elements that have been put in place – the Alice decision, post-grant review, etc. – have just begun to take effect, and they should be provided more time to work, prompting visible agreement from a number of participants. He further made the point that a fundamental issue is that while people agree at a higher level on general principles, when the actual litigation on these topics is drafted it generally extends far beyond that level of agreement. He offered the example of demand letters: “The idea was to defend mom and pop coffee shops and users like that, who were held up as the examples of who was being affected. But when the draft legislation arrived, it was a pleading minefield, that was designed to protect large, multinational companies implementing the technology in their products.”

In the interest of posting timely content specific quotes have been delivered as accurately as possible, but readers are encouraged to view the entire video of the panel for verbatim content. All in all, what was noteworthy with the panel was the reasoned, nuanced and sophisticated level of debate and discussion – which contrasted markedly with the strident accusations and name-calling that we often see when the topic of intellectual property is brought up in tech circles. Credit to Michael Petricone for assembling an excellent panel, and leading the discussion very effectively. Hopefully the level of discussion in other circles – the tech industry globally, and public policy capitals around the world – can achieve a similar level of civility and intellectualism.

In his Signals Flash roundup of the most exciting features of the recent Mobile World Congress, leading industry analyst Mike Thelander of Signals Research highlighted InterDigital’s 60GHz millimeter-wave hotspot research, which was announced at the conference in collaboration with imec. According to Thelander, “If the solution works as proposed it would make it far easier and faster to deploy high-capacity wireless backhaul connectivity to the small cell. Further, the solution could be far more resilient to disruptions in the millimeter wave radio link which requires line-of-site and the ability to cope with high propagation loss, not to mention weather-related interruptions.”

Mike Thelander is the founder of Signals Research, and has been one of the most respected voices in the wireless industry for many years.
