    Assessment of television white space availability in the Ultra high frequency band in Tanzania: a case of Dar es Salaam and Morogoro Regions
    (University of Dar es Salaam, 2019) Jumanne, Ikuje
    Television white space ( TVWS) in the Ultra High Frequency (UHF) TV hand refers to the unused or underutilized portion of frequency between 470 MHz and 694 MHz that can be utilized opportunistically by secondary devices on a non-interference basis. Frequency spectrum scarcity problem, lack of TVWS regulations and the opportunities arising from TVWS technology have been motivation factors behind this study. Apart from assessing and quantifying the available spectrum, the study aimed at demonstrating a tool that can simplify the detection of the TVWS. The study conducted in Dar es Salaam and Morogoro regions by carrying out frequency channel occupancy measurements using Frequency Monitoring systems from Tanzania Communications Regulatory Authority (TCRA) and then analyzing the results. The web-based, geo-location database tool, was also designed and developed to demonstrate the simplification on detection of TVWS. The overall results indicated that 57.14% and 89.29% of the UHF TV band equal to 128 MHz and 200 MHz of bandwidths are available as potential TVWS in Dar es Salaam region and Morogoro Municipality respectively. In rural areas of the Morogoro region, TVWS availability was found to be 100%. The performance of the implemented geo-location database tool was validated by comparing results obtained from tool execution with that of frequency occupancy measurements at the same locations. The optimal performance result was found to be 75% accurate, indicating that the tool could be useful system to simplify TVWS detection and assessment
