A revised free space path loss (FSPL) formulation for satellite link operating in tropical region

Adequate fade margins for all conditions are critical in ensuring reliable satellite operation. The required fade margin value for the specific desired quality of service (QoS) can be established from the statistics of outage due to attenuation. More power margin is typically required in mitigating...
