Right now, people pay $150+ for a package with all the TV channels, while you can get the broadband for $50 or so. Cable companies could dramatically raise prices on the basic broadband service to compensate. But that’s not going to fly in this next generation with 5G and satellite competition.
The average Netflix user watches 600 hours per year, or 50 per month. HEVC is 1.5 gigs per hour for 4K, so that’s under 100 GB per month. If data caps for 5G increase at about the same pace as for 4G, wireless data caps will be within that range within five years. Heck, AT&T’s fixed wireless is already at 160 GB per month. And Verizon has publicly stated its 5G service wonkt have the kind of data caps its 4G service has: https://www.pcmag.com/news/357374/verizon-no-4g-level-data-c....
The idea that cable providers can raise prices to compensate for lost TV revenue is predicated on the assumption that there are no alternatives. That assumption ignores just how much bandwidth 5G gives you to play with.
