His Professional Affiliation: Member of the Order of the Engineers of Quebec (Canada) Graduate Member of the Institution of Radio and Electrons Institution (UK).

The student will be able to plan microwave links with confidence and will ensure that the links are planned to offer the best performance and quality and in a cost effective manner.

• He will understand why a certain link or network is not functioning as per performance specifications and will be able to successfully resolve them.
• He will be able to select the best component for the network.
• He will have the knowledge to optimize and improve the network performance and quality.

Basic understanding of telecommunication is needed.

This course is suitable for telecommunications professionals, including transmission engineers, network planners and technical project managers who are involved in the area of planning, deployment, commissioning or operation of modern Radio-relay Digital Microwave Radio. Individuals interested in microwave communication systems are also welcome.
