This course is for anyone involved in microwave communications from those just starting out, those specifying and designing, through to the actual installation engineers. It has been designed to ensure that the student understands the components involved in creating a successful microwave link and the possible scenarios that need to be considered in this process. It aims to help identify possible areas of interference and where to obtain the informative and legal information required to make this process run as smoothly as possible.
No pre-requisite experience is required to take this course as the subjects covered will be of interest to anyone working in the microwave field although some of the lessons are quite technical and having some prior knowledge might be advantageous.
- To help the student understand some of the aspects and criteria involved in microwave link planning
