Spectrum occupancy measurements in the TV and CDMA bands

Abstract

Continuous demand, by end users, has become an issue with respect to the scarce resources of radio frequency spectrum. In this paper we conducted a 24-hour outdoor measurement of spectrum occupancy, in both rural and urban areas in Kwara State, Nigeria, spanning across the frequency range of 48.5 MHz – 880 MHz. The results obtained show that the mean average duty cycle for TV bands 1-4 and CDMA band in rural and urban locations are 2.58 % and 12.02% and 0.25% and 3.13% respectively. Findings from this measurements show that there is ample opportunity for deployment of cognitive radio for a more efficient utilization of the spectrum.
