Microwave Transmission Engineering and Link Planning

Microwave transmitter antenna on communication tower base station

This course seeks to equip participants with robust knowledge in planning telecommunication transmission networks using modern radio-relay digital microwave radio. The course will cover in detail all the important aspects of radio propagation, starting from free-space loss and absorption loss, followed by statistical analysis of various phenomena impairing radio reception process – rain, multipath fading (both flat and selective), K-factor variation and ducting. The introductory part of the course reviews basic parameters of the microwave radio systems, antenna, transmission lines and all other auxiliary equipment used during implementation of microwave radio-relay sites.

Classroom discussion of all the above topics will be complemented by interactive student exercises. The course concludes with a guide to several ITU-T/ITU-R references that participants can access for additional information.

Transmission Engineers, Network Planners, and Technical Project Managers who are involved in the planning, deployment, commissioning, or operation of modern radio-relay digital microwave radio.
