Abstract

The effect of propagation factors on high rate transmission services at microwave range is observed to be very high. The variant nature of atmospheric conditions places a major part in the distortion of original signal. Among various factors observed in signal degradation, power loss is observed to be a dominant factor. The loss in power strength degrades the receiving signal strength resulting in very low estimation efficiency. The power losses are observed basically with the variation in transmission frequency. As frequency increases, there is a crucial change to link power margins in the communication system. In addition to the free space losses, there are other losses due to atmospheric absorption, clouds, fog and precipitation, as well as multipath at low elevation angles. All of these losses due to the atmosphere at microwave range is been evaluated.
