Plenary Speakers

FPODr. William Chappell, Director of Microsystems Technology Office, DARPA

Bio: Dr. William Chappell is director of the Microsystems Technology Office (MTO). Serving in this position since June 2014, he has focused the office on three key thrusts important to national security.

These thrusts include ensuring unfettered use of the electromagnetic spectrum, building an alternative business model for acquiring advanced DoD electronics that feature built-in trust, and developing circuit architectures for next-generation machine learning. MTO creates the MEMS, photonic, and electronic components needed to gracefully bridge the divide between the physical world in which we live and the digital realm where our information resides.

Title: The Future of Intelligent Radio

Abstract: DARPA has often run challenges and programs exploring isolated autonomy, where a system can ascertain the surrounding environment and compete a task on its own. As autonomy proliferates, the further question is how will independently trained and autonomous systems work together as a collective, or ensemble autonomy. During the talk, we will explore the recently run Darpa Spectrum Collaboration Challenge, or SC2.

We will interpret the results of the first phase of our exploration of ensemble autonomy where we used collaborative sharing of the spectrum as the medium of cooperation. Many independently trained or programmed systems had to gracefully interact and the capabilities/limits of what is possible today started to emerge. We will discuss this progress as well as the associated RF hardware allowing for radios to have the needed intelligence.

FPODr. Thomas Cameron, Director of Wireless Technology, Analog Devices

Bio: Dr. Thomas Cameron is the Director of Wireless Technology at Analog Devices. In this role he contributes to industry leading innovation in integrated circuits for radio basestations and microwave backhaul systems. He is currently working on the research and development of radio technology for 5G systems in both cellular and microwave frequency bands. Prior to his current role at Analog Devices he was Director of Systems Engineering for the Communications Business Unit.

Dr. Cameron has over 33 years of experience in research and development of technology for telecom networks including cellular basestations, microwave radios and cable systems. Prior to joining Analog Devices in 2006, he led the development of a broad range of RF systems and technologies over his career at Bell Northern Research, Nortel, Sirenza Microdevices and WJ Communications.

Dr. Cameron holds a Ph.D. in Electrical Engineering from the Georgia Institute of Technology. He has 7 patents in wireless technology and has authored numerous technical papers and articles.

Title: Radio Architectures and Technologies for 5G mmwave Systems

Abstract: The ever increasing demand for mobile data continues to drive the expansion of mobile network capacity globally. As available spectrum becomes scarce in the traditional cellular bands, the industry looks to utilize the broad available spectrum in mmwave bands. Whether the use case is fixed or mobile connectivity, it has been demonstrated that the challenging propagation characteristics at mmwave frequency can be overcome through beamforming techniques. We are still in the early days of mmwave mobile systems, and there is still much to be learned, but technologies are evolving to meet the requirements of these new systems, from radio architectures, semiconductor processes, packaging and assembly, and test methodologies.

In this presentation we will discuss two common radio architectures utilizing analog beamforming, one suitable for low EIRP and one for high EIRP. An efficient signal chain will be described for each use case and optimized semiconductor technology choices will be discussed for each architecture. Finally we will briefly review the how a fully digital beamforming approach compares to the above described analog approaches, and technology requirements to enable digital beamforming architectures for future mmwave systems.
