5G and Electromagnetic energy (EME)


Every time a new generation of mobile technology is being rolled out, there are scare stories about the radiation, cancer, etc. I last wrote a post on this topic back in 2011 and also in 2009. The main thing that has changed since is that 5G is being rolled out today as 4G was being rolled out then.

The Australian operator Telstra recently completed extensive testing of their 5G network infrastructure in real-world settings using commercially available 5G devices, and their data confirms two things. Firstly, the 5G technology produces electromagnetic energy (EME) levels at around 1000 times below the safety limits in many cases. Secondly, all the testing has found 5G EME levels to be similar to 3G, 4G and Wi-Fi. You can read the details and complete report here.

Last month I went to a seminar titled 'Update on Current Knowledge of RF Safety', organised by CW Radio Technology Group and National Register of RF Workers. Richard Hargrave from BT explained the challenge with compliance when a 5G carrier is added.

The implications as he said are:
  • Some sites in urban areas become increasingly difficult to provide required capacity while maintaining compliance using standard designs
  • Significant time and cost can be associated with works necessary to ensure compliance – new planning permissions, physical structures, new site acquisition etc
  • As 5G is deployed further, particularly as additional spectrum is auctioned in 700MHz and 3.6-3.8GHz bands these problems will be exacerbated

His presentation is available here. Another presentation from Moray Rumney, asking some tough question on 5G safety is available here. Simon Rockman has written a summary of this seminar on Forbes, here.

I heard the Swiss operator Sunrise mentioning in a presentation at 5G World 2019 that the EMF limit in Switzerland is 10 times stricter than the rest of the world. This implies that 5G in Switzerland is extremely safe. The slide from the presentation can be seen in the pic above.

We also have couple of related videos on this topic, maybe of interest:

  1. So all the news that birds are dying because of 5g were fake. I dont understand how some people do not want to evolve.
