Michael Grotticelli recently featured InterDigital&rsquo;s TV White Space research in the latest issue of Broadcast Engineering. In a comprehensive piece, Grotticelli speaks with our Vice President of InterDigital Labs, Narayan Menon, who is helping to lead the research efforts in the area. The piece is available <a target="_blank">here</a>.
TV White Space and the use of unlicensed spectrum is a major effort at InterDigital, and our company is without question among the world pioneers in the area. Over the past year we&rsquo;ve announced the <a href="http://ir.interdigital.com/releasedetail.cfm?ReleaseID=715157">world&rsquo;s first demo of Wi-Fi access over dynamically-selected TV White Space</a>, as well as a <a href="http://ir.interdigital.com/releasedetail.cfm?ReleaseID=743050">successful demo of long-range Wi-Fi over unlicensed spectrum</a> at this year&rsquo;s Mobile World Congress in Barcelona.

InterDigital was mentioned in a wonderful article today by Caroline Gabriel of Rethink Wireless, who wrote <a target="_blank">this piece</a> regarding our joint announcement of Wi-Fi/LTE integration in small cells. You can read the press release at ip.access&rsquo; website, <a target="_blank">here</a>.
Small cells are an important operator-focused solution, and much of the talk in the mobile space over the past year has been on Wi-Fi/cellular integration &ndash; including a <a title="Wi-Fi/Cellular Integration White Paper" href="http://www.interdigital.com/wp-content/uploads/2012/08/Cellular_WiFi_Integration-White-Paper.pdf">white paper that we wrote</a> outlining various technology approaches to the issue. The technology with ip.access gives operators the capability to integrate LTE and Wi-Fi within small cells, and what that allows operators to do is maintain Quality of Service (QoS), regardless of network, while intelligently managing network resources.
The demonstration will be part of ip.access&rsquo; booth in Hall 7 Stand E105 at Mobile World Congress, and stay tuned for a breakdown of the various technologies we&rsquo;ll be showcasing in Barcelona.

InterDigital and ip.access: Wi-Fi and LTE Small Cell Integration

Our own Jim Nolan, Executive Vice President of Research and Development and the head of InterDigital Labs, shared his thoughts yesterday on the emerging area of unlicensed spectrum. Jim&rsquo;s blog on the prestigious technology website EDN is called Waveforms, and you can read <a target="_blank">his latest post here</a>.
This is an important area: it&rsquo;s no secret that many predictions see existing wireless spectrum as insufficient for future needs. In addition, many people are looking to unlicensed spectrum or TV White Space as a possible connectivity area for machine-to-machine communications &ndash; essentially, as a means for connecting the billions of devices that could come onto the network in the next few years without having a serious impact on current wireless communications.

InterDigital&rsquo;s Wi-Fi (DSM-Wi-Fi) and LTE (DSM-LTE) solutions are being designed for standards-based interoperability to enable scalable and cost-effective solutions. InterDigital is working actively to lead initiatives within key standards&nbsp;such as ETSI, 3GPP and 802.11 to foster adoption of spectrum sharing capabilities. InterDigital is working across the ecosystem to drive market adoption and live demonstrations of its DSM solutions are being featured at DySPAN 2012.
The 6th annual IEEE Symposium on New Frontiers in Dynamic Spectrum Access Networks (DySPAN 2012), the leading international conference dedicated to the advancement of cutting-edge wireless technologies and associated regulatory policies, takes place 16&ndash;19 October 2012.
In conjunction with the symposium, InterDigital also published a new <a href="http://www.interdigital.com/wp-content/uploads/2012/10/InterDigital-DSM-White-Paper_Oct2012.pdf" target="_blank">Dynamic Spectrum Management white paper</a> --&nbsp; providing a technical overview of spectrum harvesting through the allocation and aggregation of contiguous and non-contiguous licensed, unlicensed, and TV white space frequency channels.

Dynamic Spectrum Management Demo Featured at IEEE DySPAN Conference

On June 18th, Angelo Cuffaro, Senior Director of InterDigital Labs, participated in an IEEE webinar panel along with industry experts from Texas Instruments, Shared Spectrum and Aviacomm.&nbsp; The panel presented their views on how they believe the industry should address the impending bandwidth crunch.
Panelists discussed key topics within the spectrum harvesting space, including coexistence of secondary devices within spectrums like TV WhiteSpace, steps needed to enable spectrum sharing on a wider scale, the benefits of spectrum sensing in spectrum sharing models, and the requirements for RFIC transceivers to meet FCC requirements for non-interference within the TVWS broadband.&nbsp; To hear the panelist&rsquo;s assessment of these topics, and to view the full webinar, visit the IEEE site <a class="offsite" href="http://event.on24.com/eventRegistration/EventLobbyServlet?target=lobby.jsp&amp;eventid=801884&amp;sessionid=1&amp;key=CEE186300750694D07BAFB703B563B4D&amp;eventuserid=100442121">here</a>.
Other key takeaways from the webinar were the poll results from the audience of approximately 140 participants.&nbsp; When asked if spectrum harvesting was a viable model, 92% responded yes.&nbsp; Votes on the best way to address a potential broadband crunch were a little more split, with the most popular option (50%) being the ability to share underutilized spectrum like the TVWS model:

<img class="size-full wp-image-3248 alignleft" title="VTC logo" src="http://www.interdigital.com/wp-content/uploads/2012/09/VTC-logo.jpg" alt="" width="150" height="51" />InterDigital engineers played a prominent role at the 2012 IEEE 76th Vehicular Technology Conference (VTC2012-Fall)earlier this week. Three separate speakers presented the company&rsquo;s advanced solutions for the next generation of wireless:
Policy-driven bandwidth management techniques that factor in various conditions to enable a user&rsquo;s data to be routed over a cellular or Wi-Fi&reg; network &ndash; dynamically switching between networks, combined across several networks to aggregate bandwidth, or segregate multiple applications simultaneously among several networks. While fully transparent to the user, these innovations significantly improve network capacity and make quality of service more predictable.
Advanced waveforms that achieve high throughput performance in non-contiguous and opportunistically available frequencies &ndash; centered around filter bank multicarrier modulation and its variations - whereby prototype filters are designed to achieve certain frequency and time domain localization.
Dynamic spectrum management for harvesting additional capacity from TV white space and under-utilized frequency bands to supplement existing cellular and Wi-Fi systems. The company&rsquo;s comprehensive dynamic spectrum management technologies address more efficient utilization of the finite resource that is spectrum &ndash; a critical new frontier.

Putting theory into practice, the company also featured a live demonstration of its Smart Access Manager (SAM), a policy-driven client that enables smartphones, tablets and other wireless devices to make intelligent traffic management decisions using Wi-Fi, 3G and LTE networks. The SAM client dynamically directs traffic flows by type of application, resulting in optimized connectivity and enhanced service provider visibility and control. Its availability on Android and Windows platforms provides MNOs, MVNOs and device OEMs with the ability to offer seamless and secure policy-driven Wi-Fi handover as a differentiator &ndash; a key capability given the increasing use of mobile devices for data-rich applications such as streaming video.
VTC2012-Fall was held 3-6 September 2012 at the Qu&eacute;bec City Convention Center in Qu&eacute;bec City, Canada. This semi-annual flagship conference of the IEEE Vehicular Technology Society brought together individuals from academia, government, and industry to discuss and exchange ideas in the fields of wireless, mobile, and vehicular technology. The event featured world-class plenary speakers, tutorials, and technical as well as application sessions.
