Why bring up ADSL2? It's not a long-distance protocol at all, you need to be within 2 miles of the exchange hub to reach that 12Mb/s that you quoted. That's probably fine for subscribers within the city limits, but for more rural areas it's hardly relevant. DOCSIS techniques (cable rather than telephone modems) had quoted distances of 20-50 miles IIRC (although I can't seem to find any authoritative figures on that, probably due to search engine deterioration).
- simfree 3y agoPlenty of CAF, RDOF, BEAD and similar program funding went to forklifting ADSL2 cabinets into rural locales to provide the service OP mentioned. These were often back hauled by bonded SHDSL or similar Ethernet over Copper technologies, so you end up with a bunch of people on 12Mbps connections sharing a small pool of bandwidth, resulting in congestion, jitter & packet loss for everyone. Deploying fiber would have not been as inexpensive to implement though, and for many years getting any connectivity was more important than delivering future proof connectivity.
