Planning Digital Microwave Point-to-Point Systems

ELP 0110  ★★   

The training presents the design process of digital microwave point-to-point systems. Such systems are widely used by fixed and mobile telephony operators as well as for military purposes. During this course attendees obtain necessary theory and study detailed aspects of planning process. The most important parts of the course cover the following subjects: radio wave propagation theory, types of fading, parameters and configuration of radio equipment (antennas, waveguides, modems), frequency planning, interference conditions and link budget. Finally, the course also presents a detailed case-study example which summarises the knowledge provided.

Target audience – Who should attend and benefit

This course is addressed to individuals responsible for planning, engineering, operating and maintaining digital microwave point-to-point radio systems. Practical and theoretical knowledge would be valuable for both technical professionals and engineers.

Prerequisites – What you are supposed to know prior to the course

Ability to understand technical subjects. Some familiarity with basic algebra would be helpful. Technical background in telecommunications would also be an advantage when attending this course. A scientific handheld calculator or a laptop is recommended due to some practical exercises.
