Popis: The estimation of the electromagnetic signal power losses is a very important step in the design of radio systems. The main objective of this study is to find out the effect of Atmospheric variations on the RF transmission, as the signal propagate through the atmosphere. Two transceivers (Zigbees) at 2.4 GHz at known distance are used to measure the received signal strength (RSSI) and an autonomous weather station (AWS) measures the surface atmospheric parameters simultaneously. The hourly average variations in the relative humidity and the transmitted signal strength are closely observed to be inversely related. Attenuation correlation coefficient with the atmospheric parameters for the month of December 2014 and February 2015 is ∼0.4 and 0.6 respectively. Presented results of attenuation will be very useful for communication system design engineers in the regions of goa.
