A Survey on Dynamic Spectrum Access in TV White Spaces

PhD Qualifying Examination


Title: "A Survey on Dynamic Spectrum Access in TV White Spaces"

by

Mr. Xiaojun Feng


Abstract:

Recently, the Federal Communications Commission (FCC) in the US released 
the final rule to make digital TV white spaces available for unlicensed 
broadband wireless devices. Compared with current 2.4GHz ISM band which 
WiFi operates on, spectrum in TV white spaces can provide much better data 
rate and coverage due to the superior propagation properties. The new FCC 
rule can cause the next wireless revolution. In this survey, we take an 
overview of the current proposals for new dynamic spectrum access schemes 
in TV white spaces. We begin by some background knowledge about TV white 
spaces and the FCC rules. Then we summarize key challenges in several 
aspects in building a dynamic spectrum access system on TV white spaces, 
such as System Architecture, Spectrum Sharing, and AP Discovery. Existing 
solutions and our considerations are both presented for each of these 
aspects.
