Television (TV) stations broadcast in the very high frequency (VHF; 30-300 MHz) and ultra high frequency (UHF; 300-900 MHz) bands. Opposite to the small cell philosophy popularized by modern wireless telephone service, free-to-air TV broadcast is historically driven by the need to extend the area of coverage, as doing so will garner a larger audience. So, commercial TV transmissions utilize tal...
Cognitive radio (CR) is seen as one of the enabling technologies for realizing a new regulatory spectrum management paradigm, viz. opportunistic spectrum sharing (OSS). In the OSS paradigm, unlicensed users (a.k.a. secondary users) opportunistically operate in fallow licensed spectrum on a non-interference basis to licensed users (a.k.a. incumbent or primary users). Incumbent users have absolut...

In this paper, we propose the novel concept of a spectrum database for improving the efficiency of spectrum utilization. In the current design of TV white space spectrum databases, a propagation model is utilized to determine the spectrum availability. However, this propagation model has poor accuracy for radio environment estimation because it requires a large interference margin for the PU co...
A new regulatory debate has sprung up around the pricing of TV networks on cable and satellite systems. Many argue that bundling networks on tiers, rather than selling channels individually, is anti-consumer and forces families to purchase programming they don't value and often find ofensive. The Federal Communications Commission, after issuing sharply conflicting reports on the subject, is con...
