SpecNet: Spectrum Sensing Sans Frontières

September 5, 2011
Vishnu MSR India Navda | MSR India

While the under-utilization of licensed spectrum based on measurement studies conducted in a few developed countries has spurred lots of interest in opportunistic spectrum access, there exists no infrastructure today for measuring real-time spectrum occupancy across vast geographical regions. In this talk, I’ll present the design and implementation of SpecNet, a first-of-its-kind platform that allows spectrum analyzers around the world to be networked and efficiently used in a coordinated manner for spectrum measurement as well as implementation and evaluation of distributed sensing applications.

This is a joint work with my colleagues Anand, Krishna, Ram and Venkat at MSR India, and Chandra Murthy at IISc.
