Opportunistic Networking via Dynamic Spectrum Access
 

Victor Bahl
Microsoft Research


About the talk:
Anticipating the 2009 analog-to-digital TV transition, the Federal Communications Commission issued a landmark ruling on Nov. 4, 2008, voting unanimously in favor of opening unused television frequencies, called white spaces, for unlicensed use. Regulators around the world want to follow suit and are watching the United States closely. To some, this is the biggest opportunity in wireless communications since GSM. To others, it is an irresponsible act that will interfere with television broadcasts, rock concerts, and church services. To me, white space networking is the first main-stream manifestation of a powerful idea - opportunistic dynamic spectrum access networks. This idea can revolutionize spectrum management and solve the spectrum scarcity problem for good. WSNs have captured the imagination of the world and we must get it right! I will discuss our thinking on the societal, policy, technical, and business issues. I will describe technical challenges we have identified and solved and will convince you why white-space networking is an exciting research topic and the next frontier of wireless Internet connectivity.

About the speaker:
Victor Bahl joined Microsoft Research in 1997. Since then, he has made seminal contributions in the area of wireless & mobile systems design, including building and deploying the world's first indoor location determination system, the world's first Wi-Fi hot-spot network, the world's first multi-radio single network system, the world's first wake-on-wireless system, the world's first white space urban-area network and in community mesh networking,. His research has been incorporated into multiple Microsoft and non-Microsoft products and in industry standards. He has authored over 100 papers with more than 9,500 citations; 75 of his 120 patent applications have issued. He has won best-paper awards at premier conferences and delivered more than two dozen keynote talks. He founded ACM SIGMOBILE, the ACM Mobile Computing and Communications Review, and ACM MobiSys. He has co-founded and served on the steering committees of ACM MobiCom, IEEE DySPAN, IEEE COMSWARE /COMSNET, IEEE ISWCS, ACM SenSys, ACM MobiHeld and ACM MCS. In 2001, he was awarded ACM SIGMOBILE's Distinguished Service Award, In 2004, Microsoft nominated him for Innovator of the Year award. He is a Fellow of the ACM and the IEEE. When not working, he loves to read, travel, eat in fine restaurants, watch action sci-fi flicks, and spend time drinking with friends and family. More on him at http://research.microsoft.com/~bahl/
