Abstract

This paper presents an analysis on UHF TV spectrum occupation as  a support for deployment of an indoor and outdoor Cognitive Radio-based  campus network at Federal University of Pernambuco, Brazil. Different from  previous works, spectrum measurements campaigns and analysis on  propagation models for building of geo-location databases were performed  considering indoor and outdoor environments. The adopted methodology may  be applied to different scenarios. Results show the feasibility of deploying an  opportunistic campus network in UHF TV bands (75% of availability) and that  the selection propagation model may vary according to the location and  environment type, where three approaches were presented.
