A correlation between RSSI and height in UHF band and comparison of geolocation spectrum database view of TVWS. 8th EAI International Conference on e-Infrastructure and e-Services for Developing Countries (Africomm 2016), 6-7 December 2016, Ouagadougou, Burkina Fasohttp://pubs.cs.uct.ac.za/archive/00001142/01/rmaliwtu_africomm_tvwsheight_paper.pdfhttp://hdl.handle.net/10204/93488th EAI International Conference on e-Infrastructure and e-Services for Developing Countries (Africomm 2016), 6-7 December 2016, Ouagadougou, Burkina FasoAn investigation into the Received Signal Strength Indicator (RSSI) dependency on receiver antenna height in UHF band is conducted. The results show a high correlation between RSSI and height on channels with high signal strength. There is approximately 2.5 dBm RSSI gain per 1m increase in height above ground up to 8.5 m. From 8.5 m to 12 m, there is no consistent observable increase in RSSI. Further more, the geolocation spectrum databases (GLSD) view of white space in the television band is compared with the ground truth. Results show signal presence on some of the channels indicated free by the spectrum database. These findings imply that an increase in transmission range of UHF links can be achieved by increasing receiver height. White space devices using A GLSD should additionally require spectrum scanning to determine clear channels.enUHF television white spaceGeolocation spectrum databaseReceived Signal Strength IndicatorRSSIRSSI vs antenna heightConference PresentationMaliwatu, R., Lysko, A.
