Electric field strength

Map of electric field strength

For the transmission (sending and receiving) of data, mobile communication masts generate electromagnetic fields, also known as non-ionizing electromagnetic radiation. You can now calculate the strength of these electric fields for each location in Switzerland on our map.

The map shows your location and the electromagnetic fields generated by Swisscom mobile communication masts in an area measuring two square kilometres. The lines show the field strength in volts per meter for the selected height above ground. The lines result from calculated points at a distance of 20 meters. The gradations are 0.5 V/m.

Threshold values infographic

Most countries follow WHO [World Health Organisation] recommendations for threshold values. Yet in Switzerland, precautionary installation value limits are ten times stricter than in most EU countries.

Transmission technology

With 5G we are introducing the latest mast technology, known as beamforming. Put simply, with this technology, the fields transmitted by the masts no longer cover a large area, but are more targeted and precise. This results in higher speeds and larger capacities within the network with lower average emissions.

How we measure

We constantly check the output of our masts, comparing it with the approved key data once a day. Accredited measuring institutes also carry out many electromagnetic field measurements on our behalf in accordance with the federal government's prescribed methodology and we are developing more accurate measuring methods using the specially designed Niro measuring robot.

Electrosensitivity

Some people who suffer from health or well-being issues attribute the cause to electric fields, although there is no scientific proof or medical diagnosis of this. These complaints are real, however, and we support the efforts of the federal government in offering help to people who suffer from electrosensitivity.

Calculation basis

The actual output and the daily mean value of all Swisscom masts within the two-kilometre square areas are used to calculate the field strengths. The field strength is calculated every 20 metres, at around 10,000 points. These values differ from the field strength values on the site data sheets. These calculate the maximum possible field strengths of a single system with the full approved transmitting power to the decimetre.
