T plans much bigger splash in territory starting soon as well. Large buildings and groups are being fought over hard by AT&T, Verizon, Comcast, and others. Verizon brought Fios fiber to this market almost a decade ago, as did local independents. Comcast is offering gigabit coax, which it is soon offering to all ~40M homes as well.
AT&T jumped in more recently, led by Ed Balcerzak of their DirecTV division. DirecTV has millions of lines of coax bringing TV from rooftop antennas, a natural opportunity for broadband. Reporters see the new announcement as the kickoff of a major move with G.fast.
In selected neighborhoods of ~65% of the U.S., AT&T will consider running fiber to the basement or WTTR - Wireless to the Rooftop - plus G.fast at 500 megabits.

The technology available earlier but Dell'Oro analyst thinks telcos will move slowly. Adtran, Broadcom, Huawei, Sckipio, & ZTE are demonstrating the next generation of G.fast gear, which presumably will be generally available in early 2018. AT&T, BT, Century, and others have plans to move aggressively, but Tamboli believes the large volume will be in 2019.
'Operators are holding off on massive deployments throughout their networks until they have more hands-on time with amendment 3 chipsets and systems, which will be available in early 2018," he believes. "Furthermore, many operators that wish to deploy G.fast into larger buildings via FTTB architectures are waiting for 32 or larger port units"

Cerberus offering it to customers. BT fell a little behind schedule but will cover several hundred thousand homes with G.fast this fall. 10 million are promised by 2020. The retail ISPs are now active, with Cerberus offering the service on its web site.
"Up to 330 down, 30 up" costs 90 pounds including VAT, $117. "Up to 160 down" costs a little less. BT's fiber home is actually a bit cheaper.
Cerberus reports, "BT will only allow an order to be placed where the availability checker states that the predicted speed is 80.01Mbps or higher." The reach is estimated at ~300 meters.

"Multi-Gigabit Fast Access to Subscriber Terminals" is a new proposed ITU standard. 2020 is the target date for deployments. Jochen Maes of Alcatel/Nokia has been bringing his prototype 5 & 8 gigabit systems around the world since 2014, impressing telcos from Germany to Australia. He uses more frequencies, full duplex signalling, and other optimizations to get extraordinary performance.
Adtran's simulations are that 4 gigabits can go ~75 meters using 424 MHz. 848 MHz can deliver 8 gigabits ~30 meters. (Phone wire, ideal conditions. Coax would have longer reach.)
Either would be great for the 55 families in my six story New York building. The simulations from Adtran and others in the standards groups have consistently predicted what the actual performance would be.

Deutsche Telekom and NetCologne have tested it. Adtran thinks they will be able to ship soon, but NetCologne doesn't expect much until next year. Broadcom's Greg Fischer confirms to me, "We entered production with 212 MHz G.Fast devices last quarter and also released production standards compliant iDTA. We’re working with standards groups to assure same with cDTA."
212 MHz should deliver as much as a gig up to about 200 meters.

Next year, 260,000 lines. Cologne and Munich city nets have long been outclassing DT, especially with fiber deployment. CEO Timo von Lepel gets it, "One day, 100 Mbps will be the lowest data rate available." They have installed 25,000 kilometers of fiber, including to the basements of most substantial buildings. They run VDSL at 50-100 megabits to most apartments, but will rapidly replace that with G.fast.
They plan to use 212 MHz of bandwidth for speeds over 1 gigabit. At Anga Com, they showed download speed of 1.6 gig and upload of 200 megabits with equipment from ZTE. In the picture next to the speed test are Sun Jie of ZTE on the left, von Lepal and Horst Schmitz on the right. They have good reason to smile.
Apparently, ZTE is using Broadcom G.fast chips. They expect the 212 MHz chips to be in limited supply until next year.
