Electromagnetic fields (EMF)

All uses of radio spectrum generate electromagnetic fields (EMF) and there are internationally agreed guidelines published by the International Commission for Non-Ionising Radiation Protection (ICNIRP) to help ensure services operate in a way that will not adversely affect health. These guidelines include limits on EMF exposure for the protection of the general public. We refer to these limits as the “ICNIRP general public limits”.

To ensure spectrum users continue to operate services which will not adversely affect peoples’ health, we are proposing to incorporate the ICNIRP general public limits into spectrum licences.

On these pages you will find information on how to comply with Ofcom’s proposed rules on EMF. This includes an EMF calculator which you can use to assess compliance.

General Notice of Licence Variation

On 1 March 2021, we published a General Notification giving notice that we are proposing to vary the vast majority of Wireless Telegraphy Act licences. This is in order to formally require licensees to comply with the ICNIRP general public limits.

For more information on the variation process, you can read the full General Notice of Licence Variation.
