Next Generation Geo-location Databases

Speakers: Moustafa Youssef
Topic(s): Computer Systems,Emerging Technologies,Measurement & Evaluation,Networks


FCC regulations allow unlicensed usage of unoccupied portions of the UHF spectrum. Spectrum opportunities are mainly governed by geo-location databases that determine the set of available channels for a specific location. The protection area of the geo-location databases are usually based on the locations of TV towers and propagation models.

In this talk, we argue that current geo-location databases lead to significant wasting of spectrum opportunities, especially in spectrum hungry urban areas. We start by identifying the wasted spectrum opportunities, both temporal and spatial, for unlicensed usage. We then present DynaWhite; a highly-dynamic, real-time, and fine-grained geo-location database architecture that is capable of detecting and providing higher spectrum opportunities for future TV band devices. We also present a technique for an unconventional sensing TV sensing. Finally, we identify challenges that have to be addressed to make this new generation of geo-location databases a reality.
