Abstract-Continuing proliferation of wireless devices exposes humanity to the reality of the twin challenge posed by finite frequency spectrum and almost infinite demand for the same frequency spectrum, necessitating the need for more ingenious spectrum management techniques. The band 2.4-2.7 GHz was originally created and classified for ISM, 3G, UMTS and WiMAX systems. It has become a frequency band which is generally used by end users due to the fact that it's inexpensive, easy to deploy and enhances frequency re-use. Quite a few measurements have been carried out in countries like France, Germany, India, Romania, UK and USA. This paper presents a study of an outdoor measurement on spectrum occupancy in both rural and urban areas in Kwara State, Nigeria, spanning across the frequency range of 2.4 GHz -2.7 GHz. The results show that the band being investigated is immensely underutilized with upper and lower occupancy values of 22.56% and 0% in urban and rural environments. These results were compared to other measurements conducted globally in this band or closely aligned bands.Index Terms-ISM band, spectrum occupancy, spectrum utilization, UMTS network.

“…Two major strategies for identifying TVWS were proposed; the sensing and the geo‐location database. In the latter, SUs are allowed co‐channel reuse of the TV spectrum at the so called keep‐out distance [1, 2] to guarantee non‐interference and is considered as an immediate solution by the regulators. Several studies have sought to maximise the available TVWS for SUs in accordance with the regulatory guidance on interference.…”

“…Comprehensive studies in [24][25] [29] [30] have demonstrated the importance of using an appropriate propagation model in signal prediction. However, an optimized model presented in [31] and the algorithm presented in [30] was used in the prediction of the service coverage and subsequently the protection margins for the primary transmitters.…”

This research is focused on evaluating the amount of television white space (TVWS) in the UHF band in Nigeria. The work takes a new perspective called the Geo-spatial approach in quantifying the available TVWS. Spectrum sharing model was developed from the protection viewpoint where the secondary users (SUs) are only allowed to reuse the spectrum outside the keep-out distance from the broadcast transmission grade B contour of the primary users. The spatial data used include the administrative map of Nigeria showing the states' boundary delineation and parameters for all the TV transmitters, including their coordinates. The broadcast range of transmission and protection contour of each UHF transmitter in Nigeria was obtained using the developed models. To show the broadcast range, the transmitter position, represented by a point, was subjected to GIS Buffering operation using the Analysis Tools extension within the ArcGIS ArcToolbox. Results obtained show that the proposed method recovers more white spaces when compared with the traditional command-and-control spectrum model. The work also provides the channel occupancy distribution of Nigeria, United Kingdom and the USA for the purpose of comparison.
