    Effective utilization of future wireless communication systems such as the TV White spaces depend largely on the availability of free unused spectrum within the 470 – 860MHz UHF band. The paper, analyses the effectiveness of TV White space for last mile delivery of broadband based on spectral availability. The survey was carried out on a spectral range of 470 – 870MHz within the study area, using a RF spectrum analyser and the readings were presented using graph plots through the aid of Touchstone PC spectrum analyser. Fixed measurement was adopted and two (2) sites were chosen to take measurement. The results revealed that, 64% of the 50 channels surveyed were dormant. The degree of occupancy was found to be very low, thus providing for unused spectra spaces within the UHF frequency band which can be used to provide broadband services in sparsely populated rural areas; where data rate could be compromised for range at zero or low cost for acquiring operating spectral license
