Yes. Telephone companies can do this. You are correct about it. I don't have an answer to your question so I'm just speculating over here and it's quite possible that I'm wrong I think as soon as that happens (someone shuts off a network) someone else will set up new networks to provide the old service. Open source technologies exist to set up base stations right now [1] I think we're headed towards an open spectrum future. Soon most communication could take place on unliscenced networks [2]. Or more and more networks could become unliscenced. The G networks are not the only way to communicate. It is also important to note that the G networks are now simply internet enablers. I don't have any data on this but I'd love a comparision of telephony and data services on use today. How much data people use in calling vs using Facebook for example? Also consider that all telephony comapnies are betting big on IOT.How many IOT devices works on a G network? If you have a modern device all you need is WiFi. That however does not mean that telephone companies would cease to exist. Someone still has to provide infrastructure. They just won't have to spend so much on acquiring liscence s. Which also means more competition from unliscenced providers. Device manufacturers would be able to work on a common network technology stack. By the way I don't have anything against 5g. I also don't quite understand health implications so I'm unqalified to talk about it. But I don't like having to buy a new device just to use a new network.
