Training Focus
This training course is presented as a three-day (theory) or a four-day (theory and practical) course. The three-day theoretical training course provides trainees with a strong background in microwave transmission and link planning for modern point to point Digital Microwave Radio.
The course also covers in detail all important aspects of radio propagation, such as multi-path fading, free space loss, reflection and refraction.
Microwave links are required to perform as the backhaul of the network of all the mobile technologies today, with an ever increasing demand for capacity. If designed appropriately the links can deliver this performance. The course offers knowledge of planning microwave links. Topics covered are microwave devises, typical antennas, feeder cable, path profiles, line of sight, antenna diversity, modulation schemes and frequency bands.
The four-day course offers an additional day to provide practical knowledge of planning microwave links. The trainees will perform an installation of a microwave link for which they have done the planning. Measurements of the incoming signal will be performed on the link once installed. The measured results will be compared with the results obtained from the planning. This can also involve fault finding if the figure of the planned link does not reflect the measured signal level of the installed link.

After completion of this course, participants will:
▪ Understand essentials of microwave transmission and link design for point to point systems
