Advanced Microwave Transmission Engineering

Course Duration 3-day Instructor-led course

Key Benefits This course is designed to study the essentials of transmission network planning in greater detail such that at the end of this course the student is able to plan microwave networks such that the link Performance and Availability objectives are met and paths are designed for lowest possible design and maintenance costs. Also the system does not suffer from interference, or disturb other radio system in the vicinity. Finally student can carry on the detailed network analysis and optimize the network performance of any operational network.

Pre-Requisites for Participants Knowledge of Microwave and Link Planning. Students should have attended the course “Microwave Transmission Engineering & Link Planning Course”

Who Should Attend? Transmissions Radio Link planning Engineers and those who are or shall be involved in transmissions network planning and maintenance and optimization.
