It's been suggested, in jest, that it might be Huawei equipment that's weaponised, but that's not the case. Probably just desensing due to high local signal strengths but interesting.
Speaking of 5G, there is work being done on a cell tower near my home. I asked one of the technicians if it was 5G.
He told me that there is congestion on 4G here and the upgrade is to add a new 700MHz 4G service. Being a lower frequency it should also penetrate houses better.
