Today, we are surrounded by a multitude of different transmitting devices, such as television, radio and mobile telephony. They emit high-frequency radiation fields into the environment at different transmission powers. In the electromagnetic spectrum, the high-frequency radiation range is between 30 kHz and 300 GHz. Nowadays, many people take mobile telephony for granted.

To ensure nationwide coverage, Rhineland-Palatinate has radio networks based on the GSM standard (Global System for Mobile Telecommunication) and the UMTS standard (Universal Mobile Telecommunication System). The entire area is divided into many closely adjoining radio cells. There is a permanently installed base station in each radio cell. The individual base stations are connected to each other and to the central exchanges via cable or radio relay links.

To ensure that as many subscribers as possible can make calls simultaneously in a cell, the respective radio signals must be distinguishable. To achieve this, different carrier frequencies are used (so-called frequency multiplex system).

The frequency range of GSM systems is around 900 MHz (for the D network) and around 1,800 MHz (for the E network). The frequency band for UMTS is between 1,900 and 2,170 MHz. The great advantage of the UMTS network is that a lot of information can be passed on in a short time.

In Rhineland-Palatinate, the Federal Network Agency and the Struktur- und Genehmigungsdirektion Nord and Struktur- und Genehmigungsdirektion Süd are responsible for monitoring mobile phone base stations.
