AT&T faces intense competition from cable, talking about 10 gigabits in both directions. (Cable will only be 1 gig down, ~100 meg up, until ~2021. Verizon is serious about 5G millimeter wave, with a shared capacity of 5 gigabits. (Rarely over 1 gig.) AT&T wants something to brag about as well.
AT&T gained millions of lines of coax as part of the DirecTV deal. Alcatel and Huawei are leading the development of G.mgfast. That uses 424 MHz, full duplex, to achieve ~2.5 gigabits in both directions. The reach on telco twisted pair is only about 30 meters. On coax, those speeds can probably extend far enough to service most apartment buildings. Using 848 MHz, speeds can reach 5 gigabits.
The ITU standards group has been aiming for 2019-2020 for G.mgfast, too slow for AT&T's marketers. David Titus of AT&T wants to speed things up and have a high-speed standard for coax "early in 2018." He believes that is "doable," perhaps as an additional profile in the standard.
Titus added these high speeds should also be added to the standard for twisted pair, but he doesn't expect TP connections to be as useful in the near term.
If AT&T is interested, they must have heard from a supplier who can deliver. ?Nokia-Alcatel, ?Calix. ?Sckipio/
