IEEE Symposium on New Frontiers in Dynamic Spectrum Access Networks Celebrates in Aachen

Tue, 06/07/2011 - 2:23pm

The IEEE Symposium on New Frontiers in Dynamic Spectrum Access Networks (DySPAN 2011), the leading international conference dedicated to the advance of cutting-edge wireless technologies, recently celebrated its 5th annual event in Aachen, Germany with hundreds of international experts addressing the challenge of delivering next wave Dynamic Spectrum Access (DSA) technologies from the research stage to the global telecom marketplace.

Launched only six years ago by the IEEE Communications Society (ComSoc), IEEE DySPAN has gained rapid international prominence for its wide-ranging influence on the research and development of wireless and smart radio networking systems. This includes the building of healthy ecosystems characterized by the global commercialization of “white spaces” and related TV broadband technologies.

On Tuesday, May 3, IEEE DySPAN 2011 initiated its four-day program with a full day of tutorials dedicated to topics such as “Cognitive Wireless Networking,” “Advanced Antennas for Cognitive Radio,” “DSA Related Standards,” “Dynamic Spectrum Markets” and “Opportunistic Wireless Access: Design Decisions And Trade-Offs.”

The following day, the conference then proceeded with the first of three days of technical, business and policy symposia consisting of high-level business panels, nearly 60 paper presentations and more than 25 new technology posters and demonstrations. For instance, on Wednesday morning, Reiner Liebler, the head of Division for Technical Regulations and EMC in Federal Network Agency (BNetzA) in Germany, spoke at-length about the “Cornerstones of a Forward-Looking Regulatory Framework” and its role in “fostering investment and innovation” in addition to strengthening competition.

David Cleevely, chairman for Cambridge Radio Frequency Services (CRFS) in the United Kingdom, and Douglas Sicker, chief technology officer for the United States Federal Communications Commission (FCC), also offered their respective thoughts on “Radio Spectrum and Innovation: Realizing the Potential” and “Dynamic Spectrum Access Policy in the U.S.” In his keynote, Cleevely discussed the need for “regulatory liberalization” as a means for driving the latest technologies in a radio spectrum marketplace, which is “doubling every 30 months,” while Sicker emphasized broader policies for “enabling the availability of additional spectrum for broadband services.”

On Thursday the conference’s agenda resumed with the keynote of Pearse O’Donohue, Head of the Radio Spectrum Policy Unit for the European Commission in Belgium. Afterwards, Jon Peha, the former assistant director of the White House Office of Science and Technology Policy, offered attendees his insights into “Emerging U.S. Spectrum Policy and the Road to Innovation.” According to Peha, priorities include “making 500 MHz of federal and non-federal spectrum available over the next 10 years,” allocating billions of dollars to provide 98 percent of Americans with wireless access, developing secondary wireless markets and specifying spectrum licensing, allocations and utilization by 2016.

Another Thursday highlight entailed the high-level discussion titled “Regulatory Perspectives on Next Generation Radio Systems.” Throughout this panel, representatives of worldwide regulatory agencies elaborated on the steps necessary for “ushering the next generation of TV white space applications” and helping industry to go from R&D to policy to the successful business stage. Conclusions cited the need for standards organizations, private industry and public regulators to cooperatively develop interoperable networks that anticipate future demands, define usage rights and respond more quickly to dynamic procedures.

IEEE DySPAN 2011 then concluded on Friday, May 6 with a full array of keynotes, business panels, technology and policy track sessions. Krishan Sabnani, vice president of Networking Research at Bell Labs, began by speaking on “Spectrum and Infrastructure Virtualization for Next-Gen Cellular Networks” and the necessity of increasing capacities based on the exponential growth of wireless, mobile traffic that is tripling every year and expected to entail 2.5 billion Smartphone connections by 2015.

Following this address, Victor Bahl, the principal researcher and director at Microsoft Research’s Mobile Computing Research Center, provided his expert insights into “The Promises and Challenges of the Wireless Frontier – from 600 MHz to 60 GHz” and the development of the “world’s first urban space network.” According to Bahl, we must actively consider harvesting unused spectrum and developing greater connectivity options over unlicensed frequencies to better manage the needs of densely populated areas operating with a low number of channels.

The remainder of the day was punctuated by executive panels on “Perspectives on Cognitive Radio: The Past and Next 10 Years” and “Business Perspectives on Dynamic Spectrum Access.” During each session, industry experts from leading research institutions and telecommunications companies worldwide provided their professional opinions for reducing wireless network management costs, increasing the useful content of transmissions and sharing spectrum in new cooperative ways. Their recommendations highlighted the design of future communications built of “self-configuring and self-optimizing networks” that “reuse spectrums on a much more fine-grain basis” and “predict the emergent behaviors of interacting systems of multiple cognitive radios.”

Other 2011 conference highlights included the introduction of new and novel application demonstrations and the hosting of plenary sessions exploring issues like “UHF White Space in Europe,” Spectrum Requirements for TV Broadcast Services,” “Robust Cooperative Sensing via Cognitive Radio Networks” and “Evaluating the Economic Impact of Cognitive Radio.”

As for IEEE DySPAN 2012, the 6th annual event will be held April 3 – 6, 2012 in Bellevue, Washington.
