(2015): Short-Term Variation of Duty Cycle in the VHF and UHF Bands, Proceeding IEEE International Conference on Cyberspace, Abuja, E.S. Dandaura (eds.), 197-201.worrisome with respect to scarce resources of the radio spectrum. TV bands, spanning across has being in existence for quite a while now and much of the frequency bands, within these range, have been allocated to FM stations, TV stations and DTV stations in Nigeria. In this paper we conducted a 24-hours outdoor measurement of spectrum occupancy in both rural and urban locations in Kwara State, Nigeria, spanning across the frequency range of 48.5 MHz – 870 MHz. The results obtained show that TV band 3 was the most occupied TV band in both rural and urban areas, with occupancy of up 20.26% and 37.27% respectively. Also the mean average of the duty cycle in the urban location is 12.02% compared to 2.58% in the rural locations. Findings from this measurements show that there is ample opportunity for deployment of software defined radio for a more efficient utilization of the spectrum.enShort-TermDuty CycleVHFUHFArticle
