Abstract

In this paper we consider the use of UHF spectrum that is not allocated to digital TV transmission for unlicensed wireless devices. We model the propagation conditions and calculate the threshold necessary for detection that results in a small probability of creating interference to TV receivers. The threshold depends on the number of wireless devices. We calculated the reduction in threshold possible when multiple devices cooperate to detect the presence of a TV signal.
