The product you are talking about is called “fixed wireless access” and at least in Norway is a huge success. It makes sense because Norway is sparsely populated and this product can serve communities that are hard to reach by fiber at comparable speeds. At the same time it is both better and cheaper than satellite internet, including the spacex offerings. Spacex would make sense for even more isolated communities. Also, 5G, at least at this point, does not offer consumers anything different compared to a good 4G. But it makes a huge difference for commercial usecases. For example, Norway wants to stop using tetra. Tetra is a network used by police, firefighters etc, which offers robust communication but at a big cost and with very limited services. With 5G they will be able to use the much cheaper public network, with modern services (e.g. video calls), while maintaining robustness and traffic isolation.
