Actually 5G is far more promising and likely to provide broadband internet to the home as competiting ISP service. ATSC 3.0 has a lot of capabilities but it is up to the broadcasters to fulfill those promises. ATSC 3.0, as far as I know, will not have broadcasters becoming ISP's. However there is the capability for them to provide access to streaming services, particularly in rural areas, but this is going to be one-way are mostly downstream that's not necessarily any upstream. You would still make the upstream request using your current ISP including even satellite internet in Rural America. then the higher bandwidth Downstream would be sent through the ATSC 3.0. broadcast signal. but, and this is a very big but there is no mandate for such a service, and considering broadcasters broken promises in the past, I wouldn't count on such a service becoming reality. I really do wish all of these capabilities are implemented and the power of ATSC 3.0 comes from the fact that it is IP and that provides a multitude of very interesting services in capabilities.
