I think ATSC 3.0 on mobile is all hype no substance. No phones have a TV tuner built in, not in the US and not for other standards elsewhere like DVB-T or ISDB-T. Why would that change with ATSC 3.0? The idea of subscription services delivered over ATSC to avoid using cellular data is silly, when people get bigger and bigger buckets of data every year. Especially in a thread about fixed wireless that will feature broadband level data allotments. Using ATSC 3.0 for mobile services to avoid using mobile data solves a problem that existed 5-10 years ago, but not really today and definitely not in a few years when ATSC 3.0 stations actually appear.
