The Chinese chipmaker has been almost invisible for two years, at least in the West. They are a substantial company, now ten years old. Their CEO is a U.C.L.A. Ph.D who was successful in American chip companies until he founded Triductor in 2005 in California. The funding and market developed in China and they moved. They have a substantial business although I've seen no figures. Huawei, by far the largest telecom supplier, has a close relationship. I covered Triductor a while back, when they were considering extending their VDSL line to G.fast. Good to see another supplier confident of G.fast demand.
Lincoln Lavoie's University of New Hampshire Interoperability Lab is crucial to the future of G.fast and is strongly supported by the Broadband Forum. Broadcom and Sckipio are working hard to make their chips fully compatible because their customers want more than one choice. As so many vendors cut back, any smart buyer wants the protection of a second source.

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.

They don't intend to be left behind. AT&T's Tom Starr is one of the key engineers behind G.fast, which was developed based on the plans of British Telecom and AT&T. Their top execs have been enthusiastic about G.fast but carefully didn't commit. January 4, 2017, they announced "Experiments expanding" and that they were "encouraged" by results in Minneapolis. Cable is making strong inroads against U-Verse and destroying AT&T where they never upgraded decade-old DSL. They have to do something. They intend to abandon landlines and go completely wireless to 10M homes. The 12.5M fiber home lines are only about a quarter of their future footprint.
G.fast from basements and rooftops is the natural cost-effective choice and has strong advocates within the company. AT&T spent $billions expanding fiber to 1,000,000 business addresses. Much of that is very close to residential buildings and easy to extend. AT&T is speeding up their fiber home build, now at 4M. The 12.5M target is now moved up to mid 2019. They acquired millions of lines connected by coax to a DirecTV rooftop antenna. G.fast performance over coax is exceptional.
I've reported that T is actively looking for more buildings for WTTR, which likely will migrate from dedicated lines to G.fast.

"DSL is terrible, but it doesn’t have to be," writes Rob Pegoraro, who has written regularly for The Washington Post and USA Today. He's on target that the telcos offer about half the country an awful service, 10-15 year-old DSL at speeds of 2-10 megabits. That's terrible today and customers are flocking to cable. But he also reports that #1, AT&T and #3, Centurylink, are getting serious about G.fast at 500 megabits and more.
Rob picked up my comment, "G.fast will be a real factor in 2017 but for a relatively small number of homes," and went on to call G.fast "A new hope." My guess is that both AT&T and Century will start deploying widely in the second half of 2017.

PLDT spending $40M over three years. 500 buildings will be connected in 2017, half business and half residential. They plan 1,600 more buildings in 2018 & 2019. They promise "up to 600-700 megabits." That's realistic; today's G.fast from the basement or the roof will usually deliver 500-800 megabits.
The surprise is the inclusion of Korea Telecom's GiGa Wire using Marvell's G.hn chips. KT itself is rolling out millions of lines of G.hn, possibly faster than the worldwide roll of G.fast. G.hn can deliver high speeds without much of the cost and complexity of G.fast. G.fast engineers believe G.hn will encounter severe congestion problems as the networks add more subscribers because of the lack of vectoring. Chano Gomez of Marvell claims real world results are just fine. I'm waiting for some independent data.
Huawei is supplying the G.fast gear,

Nothing official, but the boss sure seems to have decided. CTO Ibrahim Gedeon spoke twice at Huawei's MBBF in Tokyo. It was a mobile event but G.fast was part of both of his presentations. It's a natural extension to Telus' fiber deep network. He used VDSL to bring video speed service to many homes and fiber home for others. He faces cable almost everywhere and will need to upgrade as Canadian cablecos move to a gigabit. (Videotron in Quebec is already offering gigabits. The cablecos in Telus' Western Canada region will be doing similar.)
Fiber home is working well but is costly. His estimate was $700 to connect a home and sometimes as much as $1,000. (Presumably, he was quoting Canadian dollars, currently worth 25% less than U.S. dollars. $700 Canadian is a little more than $500 U.S.)
A while back, Verizon estimated $600-$700 (USD) to connect a home; they've said it has come down substantially since then. Randall Stephenson of AT&T has confirmed fiber deployment costs have come down substantially.
