Executive Summary

A currently prevalent view of the operation of white space cognitive radios is that they should use geo-location databases to determine their frequency band and maximum transmission power in any given location so that interference radiated to broadcast receivers is negligible. To estimate the level of such interference, physical reference geometries and path loss estimates have been proposed between co-located devices. In this paper, the authors present results of a measurement campaign conducted over indoor and outdoor reference geometry scenarios in a digital terrestrial television test network.
