BTW, up here (Finland, northern Europe) new construction code for so-called zero-energy houses mandates energy saving structures that almost make houses Faraday cages. Walls are to have aluminum foil in them to reflect radiation and keep heat in. The foil also reflects or blocks radiation from communication devices. Also windows have layers that try to block radiation, except for visible light. So combating climate change shows up in cell phones and modems not connecting, or having poor coverage. People have to go out or keep a window open to make a call. The impact is particularly strong with higher frequencies, so generally, the newer the technology, the worse it is. House owners have started to install repeaters, but FICORA (local equivalent of FCC) says those are illegal. I haven’t heard of solution proposals for this catch-22, government agencies each work in their own silos.
