TV white space is the unused TV spectrum which can be used by secondary users to solve the problem of spectrum scarcity and to increase its efficiency. This has become necessary as a result of rapid growth in wireless data traffic, ubiquitous connectivity to the end users which is of high interest in the communication world today. This paper takes a look on analyzing the availability of the TV white spaces in the digital terrestrial television bands in Delta North area of Delta State Nigeria. The frequency span analyzed is between 474-866MHz. The result shows that over 60% of the spectra in this area are underutilized, yet we have high alarming rate of spectrum scarcity by the communication industries. Most of the smart devices competing for these scarce spectra can be deployed to these unutilized spectra at low or no cost thereby freeing most of the spectrum bands. Our analysis shows that we have over 224 MHz frequency bands that are free to be used within this area. The data used for this work was retrieved from a DVB-T2 and Anritsu Ms2711A Spectrum Analyzer. This was connected to Metrodigital mega base station that provides digital terrestrial television services in this area.
