September 17, 2014 / 5G, LTE, WiFi, 3GPP / Posted By: Stephanie Stocker

PIMRC‘14 (IEEE 25th Annual International Symposium on Personal, Indoor and Mobile Radio Communications), which ran from September 2-5 in Washington, DC, was a huge success, and InterDigital is proud to have been a significant contributor. The conference was focused on 5G technologies, aligning closely with our own focus.

Conference topics ranged from innovative enhancements to network architectures to groundbreaking and potentially controversial new concepts. As the place where all sides of the industry come together to discuss ideas, PIMRC was the perfect venue for these conversations.

One panel, “Opportunities and Challenges for LTE (-U) and WiFi Coexistence in Unlicensed and Shared Spectrum,” included InterDigital’s Mihaela Beluri, and addressed the hot-button issue of LTE using unlicensed spectrum. Mihaela discussed possible solutions to what seems to be a controversial topic. Doug Castor, also one of our engineers, spoke on a panel entitled “mm-Waves Technology as an Essential Element for Next Generation Mobile Cellular Systems,” which discussed the emerging evidence showing mm-Wave as a viable solution for network capacity growth.

In addition to the panels, two sessions were chaired by InterDigital employees, with Meilong Jiang chairing “Limited/Implicit Feedback” and Ahmed S. Ibrahim chairing “Physical Layer Network Coding.” Our engineers also contributed three papers to the technical program: “Reliable RF Beamforming for Millimeter Wave MIMO-OFDM Systems” (Ahmed S. Ibrahim), “Efficient Adaptive Vertical Downtilt Schemes in LTE-Advanced Networks” (Meilong Jiang, Mohsen Hosseinian, Moon-il Lee, Janet Stern-Berkowitz), and “Sub-Channel Selection for Multi-User Channel Access in Next Generation WiFi” (Hanqing Lou, Juan Fang, Oghenekome (Kome) Oteri, Monisha Ghosh, Pengfei Xia, Robert L. Olesen).

The timing of these discussions at PIMRC is critical – not only is 3GPP discussing LTE-U for a decision expected to be released this month, but the industry is gearing up for the 2015 WRC (World Radio Conference), held every few years as a global gathering of regulatory bodies and standards groups. During that conference,  important decisions about the global use of radio spectrum and how to seamlessly deploy technologies worldwide will be discussed.

In their June issue, IEEE Wireless Communications Magazine published “Toward a Standardized Common M2M Service Layer Platform: Introduction to OneM2M”, a paper written by a team of industry experts which included Guang Lu, an InterDigital staff engineer. This article addresses a major M2M challenge – the fragmentation created by multiple proprietary solutions that do not communicate with one another.

This challenge is being met by the oneM2M Global Initiative, an international partnership project. The oneM2M standardization solution was initiated by seven major telecom standards defining organizations with the objective of reducing fragmentation of M2M service layer standards through global specifications, paving the way for M2M interoperability across industry verticals. Standards that allow for a common platform and a common set of APIs will ultimately shorten time to market, aiding a faster realization of a true M2M ecosystem.

This paper delves into the various working groups of oneM2M and the standardization efforts being undertaken by each. For even more information on M2M and the future of the IoT, please visit the InterDigital Vault.

On June 26, CommNexus hosted a panel discussion, Making M2M: Secure and Economically Viable, in San Diego, CA. InterDigital’s Phillip Brown joined the panel, which included industry experts from Tagnos, ViaSat and Verizon Wireless and was moderated by a product manager from Qualcomm.

The panel argued that one of the most important barriers to complete M2M adoption is security risks. Any solutions to potential security threats need to be both effective and economical in order to make the technology viable and marketable overall. Watch the full discussion to see what the panelists had to say. Visit the InterDigital Vault for more information on M2M.

March 10, 2014 / carrier grade Wi-Fi, Wi-Fi / Posted By: Stephanie Stocker

Monisha Ghosh, principal engineer at InterDigital, was recently published on EDN Network with “Addressing expanding wireless data usage? Turn to carrier grade Wi-Fi,” focusing on the reasons carrier grade Wi-Fi may be the solution to continuously growing data usage. With a large percentage of mobile traffic choosing Wi-Fi over cellular service when available, and increasing numbers of public Wi-Fi networks to meet that demand, overall data usage is projected to expand significantly.

Monisha argues that the solution resides in carrier grade Wi-Fi once specific challenges, including throughput, quality and deployment, are resolved. In her article, she delves into three technologies that might address these requirements: multi-user parallel channel access, uplink multi-user MIMO, and fractional CSMA and transmit power control. Read the article on EDN Network for full details.
