Ofcom has published the latest results from our spectrum measurement programme, including six additional 5G mobile sites. 

Following the launch of 5G in the UK last year, Ofcom published the results of electromagnetic field (EMF) measurements at 16 UK sites, in February. Ofcom has continued its testing programme since then and has now published an updated version of its 5G measurement report – showing EMF levels at a total of 22 5G sites in 10 UK cities. 

At every site, emissions were a small fraction of the levels included in international guidelines – set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).

The maximum measured at any mobile site was approximately 1.5% of those levels – including signals from other mobile technologies such as 3G and 4G. The highest level from 5G signals specifically was 0.039% of the maximum set out in the international guidelines.

Ofcom will continue to publish data from its measurement programme, including at further 5G sites, regularly.
