|To protect humans and nature from electromagnetic hazards, the health and safety legislation for the deployment of (cellular) base stations (e.g. LTE, UMTS, GSM, IS-95, IS-136, ...) becomes more and more restrictive. This is driven by the goal to reduce health risks especially for young children and for persons working/living close to radiating antennas.
Different public authorities issued recommendations based on guidelines formulated by the International Committee on Non Ionising Radio Protection (ICNIRP). Today, these recommendations must be fulfilled for each new transmitting antenna.
The recommendations define limits to protect the public and those working close to transmitting antennas from electromagnetic field hazards. Therefore an assessment of the radiated electric and magnetic field strength for different frequency ranges must be carried out before installing a base station or transmitter.
