Radio Transmission Introduction - Physical Fundamentals

Course description (english, PDF)

Duration: 5 days

This training is designed for technicians and engineers who are working in Wireless Communications Systems but nether had the chance to deal with RF technology in more detail. We cover the basics of electromagnetical waves, frequency and time domain, radio wave propagation and measurements. In this context we take a look into measurements and their meaning of mobile networks.

Target Group / Requirements

This training is addressed to technicians and engineers working in Wireless Communications. 

The theoretical knowledge  is applied in practical exercises in order to reinforce and strengthen the important parts of the training with personal experience.
