Portions of the Ultra High Frequency (UHF) radio spectrum which are not assigned to licensed operators (often termed as primary user) or licensed but unutilized at all times or in all locations are referred to as TV White Space (TVWS). The UHF TV band spectrum has very good wireless radio propagation characteristics. The paper attempts to study the amount of TVWS in the UHF TV band in Nigeria. Quantification assessment and estimates for the TVWS in the 470-590 MHz band for Awka, Anambra state, southeast Nigeria are presented. The average available TVWS in this area is calculated using secondary (unlicensed) user point of view known as pollution viewpoint. By this method, characterization using the developed pollution radius and tolerable interference of 5 dB is found to be 83% of the area around Awka available as white space, indicating the spectrum utilization opportunity within this area for secondary use. The characterization of the environment showed that it is an excellent environment for deployment of TVWS antennas for optimal RF utilization for the provision of broadband Internet services.
