How do the cable companies generally deliver this service? A friend insists it piggybacks off the WIFI radios of existing cable company subscribers. In other words, the cable company WIFI router in a flat is providing both a private link for the flat's subscriber, but also a public hotspot service.
I concede it is possible, but I am skeptical that the high quality of hotspot service we get here in Budapest could be achieved that way.
Calix has this option on the 844G/E CPE. The G is used with fibre based drops and the E is used with cable modems. It is called Community Wifi and is an option that can be enabled in both units. It uses GRE tunnels to backhaul traffic. Never used it so have limited knowledge on actual workings, but have deployed many of both types of CPE's.
