Facts and figures

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.

The effect of the human body on wireless microphone transmission

The allocation of the 700 MHz band to mobile communications will further reduce the spectrum available to wireless microphones. New frequency bands will have to be found to accommodate these applications. The human body plays a very important role in wireless microphone transmission and must be taken into account.

Free Space Laser Communications Systems

Free Space Laser Communications Systems are wireless data links through the atmosphere.

Radionavigation Satellite Services

Satellite navigation is playing a growing role within all areas of today's mobile society. Navigation receivers are made for aircraft, ships, ground vehicles, and for hand carrying by individuals.

Smart Antennas

Intelligent and adaptive antennas will be required to increase capacity and data transmission rates of future mobile radio systems.
