David believes his work on high frequency mm Wave, THz and FSOC based wireless networks has contributed to and expanded upon the growing international discussion on ‘fiber parity” 10-100 Gbps mobile wireless networks. But going forward, the network and societal implications of this emerging big data centric 3rd PHY layer underlay concept, as well as the impacting spectrum and regulatory issues, new network topologies, technologies and technology players, will require a comprehensive and well planned multi-prong-approach for its successful implementation. The failure to recognize and implement the need for this drastic change to our existing wireless infrastructure and market driven services will be nothing less than catastrophic for our near future industry and greater society. Our responsibility to the future is then to make these changes realizable in a timely and practical manner, to future proof our societies vital wireless networks and services.

Historically large service provider companies provided a visionary and technology leadership role that helped guide the communications industry over the last 130+ years. This vision and leadership role may now be changing and moving to broader and more diverse university and industry collaborations, a new way to address and shape the future. To address this future, the rich heritage and distributed network knowledge resource, of both people and ideas, needs to be harvested to support industry, science, engineering and Government spectrum and regulation in their efforts to address the daunting challenges of building a new super high capacity wireless infrastructure in parallel to the existing network.

To date, the communication industries enormous investment with research and technology has provided a solid foundation and critical guidance for the emergence of advanced wireless technologies including THz based communications. Going forward the communications industry must still continue to invest in the future, but now with trusted partners to help shape wireless technologies and network architectures to a capacity secure future. This new critical relationship will sustain and expand the nations, indeed the worlds evolving communications infrastructure and capacity, and especially at a time when new big data centric wireless services so critical to our smart machine age society begin their inevitable impact on humanity.

Biography of David Britz:
David until Oct 2013 was a Principal Member Technical Staff with AT&T Labs Research - Shannon Laboratories and has worked contiguously at AT&T since 1984. He is recognized internally and externally as the AT&T Research subject matter expert for Free Space Optical Communications (FSOC) and Terahertz Communications. He has been also very active in high frequency spectrum allocation and application considerations including mmWaves frequencies above current IEEE 802.11ad and 60GHz. His recent work has been directed at the conceptual system design and architecture of high frequency mm Wave, THz and FSOC based super capacity wireless data centric local area networks. These super capacity wireless networks would be capable of providing “fiber-like” 10 - 100 Gbps wireless throughputs for a broad variety of sub-kilometer applications including indoor/outdoor WLANs, neighborhood wireless networks and P2P wireless backhaul. More recently, David’s focus has been on super-data rate Small Cell networks designed to future-proof our wireless networks for the expected surge in wireless “big data.” He has received several important system-level and technology patents for FSOC and THz based systems and network implementations; in total, David has received twenty eight patents to date.

David has represented AT&T and IEEE to the FCC, NTIA, ITU and other advisory and governmental organizations, encouraging the commercial use and regulation of spectrum above 100 GHz and commercial expansion into the THz band worldwide. He is also collaborating with the US CORF, a government spectrum advisory organization, to develop means for spectrum co-existence between active commercial services and the protected passive services (Astronomy and Earth monitoring) in the THz frequency bands. Parallel to this work, David is also directly engaged in collaboration with Terahertz technology advocates and R&D collaborators (e.g. University of Braunschweig THz Center and Northrop Grumman among others) to orchestrate continuing evolution of Terahertz radio transceivers, links and system standards.

David was a founding member and Chairman of the FSO Alliance, founding member of IEC-TC76 Working Group 5 Part 12 and US delegate to the IEC on laser safety. He is also a founding member and current Chairman of the MoGIG Working Group within the IWPC industry consortium, a group focusing on technologies and network topologies required for 10s of gigabit wireless LANs. He is the founding member and current Vice-Chair of IEEE 802.15 THz Interest Group focusing on device standards for THz communications. David is currently engaged with the ITU/WRC and US CORF delegation on impending THz spectrum usage and allocations regarding “active and passive services.”

David is multiply published within the WCAI, SPIE, IEEE and Laser Institute of America and currently is writing papers for an IEEE special proceedings and the Journal of Communications and Networks (JCN) on THz wireless networks and related subjects. He has provided numerous papers and presentations on FSOC and THz networks to internal and external AT&T customers and has also participated in a number of Government, Military and DARPA FSO centric activities, as well as external subject-related conferences. His earlier work at AT&T entailed forward looking technologies, advanced product design and development including public communications products, ISDN telephones, advanced speakerphones, multi-media cellphones and the first patented cellphone with video capabilities. From the mid 1990’s, his personal background and interest in optics and telescopes further developed his technical background to include in-building and terrestrial optical wireless technology which is now being deployed in AT&T networks. David graduated from Rhode Island School of Design receiving his Master of Industrial Design in 1980.
