Hundreds of megabits to apartments for a very low cost. For a decade, millions have been getting 100 megabits from fiber to the basement + VDSL on existing building wiring. Now, there's a surge of wireless to the roof, led by AT&T in Minneapolis and Webpass (bought by Google) in San Francisco. Speeds range from 200 megabits to nearly a gigabit and system latency is good. The very visible and ambitious Starry is starting to test WTTR in Boston. They are running mmWave to the rooftop for backhaul and using G.hn to reach apartments.
** Update: I had a chance to talk to CEO Chet Kanoja. They have not seen a G.hn congestion problem and he doesn't expect problems going forward. Everyone's watching for field results. They found an ODM supplier for the G.hn at the transmitter and design their own gateways. Even more interesting, they are going millimeter wave to houses and apartments in volume. He's designed a 5 gigabit mmWave transmitter built up from 802.11ac that is point to multipoint. He says his cost is $800-$1,000, which will transform the economics. It implies he will be delivering something similar to Verizon's 5G at a much lower cost. I'll remain skeptical until that's widely deployed in the field, but the details he provided were convincing.
