EM Wave Propagation Experiment at E Band and D Band for 5G Wireless Systems: Preliminary Results

摘要

Preliminary results on an electromagnetic wave propagation experiment at E and D band are presented. The research activity is collaboration between Politecnico di Milano and the Huawei European Microwave Centre in Milan, which has recently installed short (325 m) terrestrial links operating at 73, 83, 148 and 156 GHz and connecting two buildings in the university main campus. Received power data are processed to identify and isolate rain events and quantify the fade induced by precipitation, A_R. Moreover, A_R is estimated taking advantage of ancillary data collected by a laser-based disdrometer collocated with the link transceivers. Preliminary results definitely point out the higher prediction accuracy achieved by exploiting the information on the rain drop size provided by the disdrometer.
