%X Abstract ¨C This This study investigates white spaces in the frequency range 410 MHz to 960 MHz using a programmable measurement testbed. Radio spectrum scanning was performed for a total of 144 hours (6 days at 24 hours/day) with the main objective of identifying and quantifying the white space contained in the said bandwidth as a preliminary phase in developing a repository for spectrum utilization in future work. Channel occupancy based on NTC¡¯s 2016 channel plan was evaluated herewith. Results show underutilization of the observed bandwidth, with highest average channel occupancy to be 45.12% which is utilized by Cellular Mobile Telephone System in the frequency band, 925 to 960 MHz. Occupancy results show that the observed frequency band contains a large amount of white space. This could be used for different applications, whether for connectivity improvement, government¡¯s social services or simply public awareness of the spectrum utilization. This study serves as a foundation for future studies that may include a real-time spectrum observatory and similar applications.
