Introduction
Microwave transmission Link design and network planning training course provide a strong background in the area of planning telecommunication transmission networks using modern Microwave systems. It covers in detail all the important aspects of microwave signal propagation, starting from free-space loss, absorption loss, and others, followed by statistical analysis of various phenomena impairing microwave reception process like rain, multipath fading (both flat and selective), Fresnel zones, K-factor variation and ducting based on ITU-T/ITU-R standards. Also, this course will introduce basic parameters that identify the microwave link like antenna characteristics, Tx/Rx power, modulation coding, and others. All the above can be explained and applied practically upon students’ needs with pathloss 5 including interference study and PtMP coverage map preparation.
