LANS Informal Seminar
"Opportunistic Networking via Dynamic Spectrum Access"
DATE: July 7, 2010
TIME: 15:00:00 - 16:00:00 Description:
SPEAKER: Sachin Shetty, Assistant Professor, Department of Electrical and Computer Engineering, Tennessee State University
LOCATION: Building 240, Conference Center 1404-1405, Argonne National Laboratory
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. With the advent of cognitive radio technology, opportunistic dynamic spectrum access has the potential to mitigate spectrum scarcity and meet the increasing demand for spectrum. Following topics will be discussed : 1) Introduction to cognitive radio technology and dynamic spectrum access, 2) Technical Challenges pertaining to communications and networking protocols and 3) Spectrum-aware protocol and algorithms to deal with spectrum fragmentation.
TIME: 15:00:00 - 16:00:00
