UHF Spectrum Occupancy Measurements in Sharjah - UAE

In this paper, we present the results of a spectrum measurement study conducted at the American University of Sharjah in the United Arab Emirates covering the UHF band from 300 MHz to 3000 MHz. A Gaussian mixture model is used to estimate the noise parameters and set the threshold for data analysis using three different schemes; namely m-dB above the noise floor, outlier based, and constant false alarm probability. It is shown that the UHF band has an average occupancy varying from 10% to 35%. This indicates the great potential for using some of the bands (TV band for instance) for cognitive radio applications and future 5G systems.
