Broadcom has a chip that runs something like G.fast and can work with reverse power. Anything else is uncertain and the reports contradictory. Other reporters are emailing me in Amsterdam asking for details but Broadcom turned me away from their walled in demonstration.
What we know: Adtran showed a unit with eight ports from using 2 chips. Two ports were vectored. They told me that vectoring worked across the four ports on a single chip but not across chips to allow eight or sixteen connections. Adtran also showed reverse power working with the Broadcom chips. The system also supports VDSL, apparently on the same chip.

536 Mbps and upload 116 Mbps. Telekom Austria has linked up a company offering working and event space via G.fast, the first actual customer connected. TA doesn't expect volume deployments until 2016, however. They see G.fast as an alternative to fiber for 400,000 apartments in Vienna alone. Many are older buildings where people are resistant to drilling for fiber. The French report a similar resistance to drilling.
The press release only stated, "Data rates of several hundred Mbit / s." The 536 megabit figure was confirmed to reporters at a press conference with the screenshot of the screen test and reporters in the German press. There are numerous challenges that might drive the speed down in deployment but also room for the chip designers to improve things. Alcatel supplied the equipment, using Sckipio chips. Sckipio's modem chip isn't available yet so they used a four port chip designed for the other end of the system. Sckipio expects gateway chips within six months.

"A customer" on FTTB/G.fast. Update Oct 17 We have the details. It's Alcatel and Sckipio. previous:Peter Schiefer of TA confirms, "We are going to show G. Fast with a live customer next week on Wednesday." If it is just "a customer," Alcatel may have installed a lab test style rig with FPGA's. It could be an early Broadcom chip Alcatel is testing. Broadcom as usual is keeping mum and Alcatel is offering no details before BBWF on what they have in G.fast.
Austria is talking a billion euro subsidy for faster broadband and just allocated the first 300M. That gives TA powerful incentive to showcase advanced capabilities. Management needs to look progressive. Carlos Slim already has three seats on the board and appears to be moving ahead with a takeover. Slim's Telmex knows how to run a low cost operation, crucial as Austria expands into Eastern Europe.
Telekom Austria operating in Serbia still is a surprise 100 years after Franz Ferdinand.

200-600 meg pretty fast so why hype? British Telecom, despite the BBC and other news reports, did not attain a gigabit with G.fast. They merely showed that 104 MHz over a protected standard copper line could reach speeds of 786 megabits down 19 meters, something obvious for years from the basic engineering. The substance of G.fast is significant so the hype is unneeded.
BT's results were not for G.fast. G.fast is a 300 page specification that BT/Huawei didn't even pretend to support. Many features, such as reverse power, are important and were not implemented. Vectoring in G.fast remains totally unproven and will be crucial to any deployment. Several features of G.fast are likely to reduce the speed. The effect may be relatively modest but we won't know until they are tested.

Not really a gigabit but 300-700 megabits is darn fast. Michael Weissman of Sckipio has delivered a highly integrated 4 port G.fast chip to a dozen device makers, making good on Dudi Baum's promise to have chips in 2014. He promises a CPE chip within six months and believes carriers will start deploying before the end of 2015.
"The interest is crazy," he tells me. Carriers that normally take a year or two to start thinking about things want to go to trials in a few months. "It's not just the European telcos," Weissman added. "We are seeing demand from Latin America, the U.S. and just about everywhere. Some want to go to advanced trials as soon as we can supply the gear."

Brits have homes, Germany apartments. Matt Phillips in Quartz http://bit.ly/1qGY7SC discovered Spain has more elevators per person than any other European country. 65% of Spaniards live in apartment, more than any other Europeans. That's natural for fiber to the basement/G.fast, although Telefonica is still thinking Fiber home. Switzerland is 60% apartments, Germany 53%. FTTB/G.fast is natural there. CTO Bruno Jacobfeuerborn of Deutsche Telekom has been the first to promise G.fast. Other European countries are much lower.
Brits are only 14% apartment dwellers. BT's Trevor Linney is leading in developing "fiber to the distribution point" with G.fast. In fact, they indefinitely postponed their vectored VDSL plans and are waiting to G.fast results. The DP would be the corner and cover up to 16 homes. Mike Fries of Liberty Global bought Virgin, the British cable company. Fries is putting $700M into gigabit cable in Belgium and probably will upgrade England as well. So the 300-700 megabits of G.fast appeals to BT.
