Abstract
This paper presents the study of the spectrum occupancy in the UHF frequency band (470-870MHz) in Bilbao area, Spain. The study has been performed at three different sites and at different height to determinate the hidden node margin, the main problem of the cognitive radio. The objective of the paper is to determinate by signal power measuring if the cognitive device will be able to detect and distinguish the empty and occupied channel to carry out the communication. The results from the spectrum measurements taken in all the sites have been analyzed and compared to the official spectrum regulation. The study reveals that the spectrum occupancy is minimum, thus there are a lot of white spaces in this band.
