As the world is getting more connected through cell phones, Cellular Signal Strength metrics demand more attention as parameters linked to everyday life. This paper focuses on the effects of temperature on cellular signal strength quality. In telecommunications, Received Signal Strength Indicator (RSSI) is a measure of the power present in a received radio signal. This work looks into the variation of RSSI values over temperature and its effects on cellular communication networks. The study on the effect of temperature on RSSI is performed by measuring the temperature and signal strength over a region simultaneously. Signal strength values is collected using Android Packaging Index (API) of Android smartphones and temperature using a custom made weather station.
