            Abstract : 
This paper covers unavailability of line-of-sight radio links due to rain. To evaluate the rain effects over a communication system, it is essential to know the temporal and spatial evolution of rainfall rate. Long-term 1-min average rain-rate characteristics necessary for the design of microwave radio links are determined for central Poland. 1-min rain rate distributions are presented. It also describes comparison results of predicted attenuation obtained from ITU-R formula and empirical data at frequencies 11.5 GHz and 18.6 GHz.
