Elektromagnetische Felder

High frequency fields

High frequency electromagnetic fields cover the frequency range from 100 kHz to 300 GHz of the electromagnetic spectrum. In general they are distributed by an antenna. They are able to distribute energy and information over a great distance.

Because high frequency electromagnetic fields are used for multiple purposes (e. g. radio and TV broadcast, mobile communication, cordless phones, wireless LAN and bluetooth connections) we are surrounded by a large number of different emitting facilities operating at various transmitting powers and frequencies.

What are high frequency fields?

Electric and magnetic fields in the frequency range between 100 kilohertz (1 kHz = 1.000 Hz) and 300 gigahertz (1 GHz = 1,000,000,000) are referred to as high-frequency fields. As electric and magnetic fields are closely coupled at high frequencies, they are also called "electromagnetic" fields.

Baby monitors

Baby monitors may use two different technologies to transfer noise from the nursery to parents and thus give them the opportunity to control their babies or toddlers from the distance: the electrical grid of the house or flat or a radio system. Today most of the baby monitors apply wireless communication.

Smartphone with Bluetooth

Bluetooth, Wireless Local Area Networks (WLAN), and Ultrawideband (UWB)

Bluetooth, Wireless Local Area Networks (WLAN), and Ultrawideband (UWB) apply radio frequency radiation for wireless and mobile connection of various devices for telecommunication and data processing.

Full-body scanners

Innovative full-body scanners are deployed for security checks, mainly at airports. The machines are used to detect and localize forbidden objects which may be hidden below a person's clothing.
