Actually, out here in northern Scotland, 4G could already make my
landline redundant if only there was a suitably priced plan that gave me
unlimited or nearly so download limits, but AFAIAA there isn't.
Fake news. Oxygen absorption gives 300m range. So each radio modem needs
fiber optic modems 300m apart running at 10GHz. May as well roll out
Internet of fiber first. Connect everyone with $20 SFP 10gbit symmetric
fiber modules at higher speed than 5G, and cheaply at $150 per one off
connection fee, without a £250,000 5G radio modem!
You are an absolute mine of mis-information.
Typically 5G operates at 15GHz, whose propagation will be similar to KU band satellite transmissions. I can easily receive very weak (35 - 150W - similar to mobile base stations - 25W) signals at 12G750Hz from 40,000,000m away, with the last several miles through the atmosphere.
Presumably you need a 5G radio modem at each end. Even crApple will have trouble selling phones at £250k each. You seem to have given the development cost or more likely some figure you just made up.
