The following links give an overview of the latest developments in radio technology together with descriptions of various radio systems.
Electromagnetic waves are produced to transfer information between wireless systems. The propagation characteristics of these waves are dependent on the selected frequency, climatic and geographical conditions as well as the time of day and other environmental factors.
These complex propagation characteristics lead to the development of the most diverse radio systems in the broadcasting, mobile radio and radio relay sectors in addition to radar, medical and other industrial applications.
The following links give a description of the various broadcasting (only in German or French) and telecommunications radio systems.
