In 2016, G.fast looked very promising.
Thousands worked at developing and deploying.
It wasn't enough.
Most carriers are investing
in fiber or 5G instead.

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.
I'm waiting for Broadcom to provide details. In particular, it's not clear Broadcom (or anyone) can do the heavy calculations for vectoring the higher speeds. Adtran and Deutsche Telekom announced results of their private testing of 212 MHz and cDTA. The cDTA is on Sckipio chips.
Until we get more public testing, delivery dates are very fuzzy.
G.fast technology: NetCologne and ZTE break new speed record on the Anga Com!
The Cologne-based telecommunications provider NetCologne and the Chinese technology group ZTE presented today at the Anga Com a new technological milestone. With the 212 Megahertz G.fast solution, the limit of 1 Gigabit was exceeded for the first time in the live test.
Breakthrough: 1.8 Gigabit
NetCologne continues to increase its speed and continues to take the lead over G.fast across Germany. "With the current measurements, we have reached a new record," says NetCologne CEO Timo von Lepel at today's live demonstration at the Anga Com. For the first time the speeds of more than 1.8 gigabits per second were shown outside the laboratory (download 1.6 Gbit / s, upload 0.2 Gbit / s).
New 212 megahertz profile
This new generation of chipsets is possible in the ZTE DSLAMs. During the pilot phase in the spring, NetCologne had initially worked with the frequency band up to 106 Megahertz for data transmission. As a result, speeds of 850 Mbit per second have already been achieved in real operation. With the new 212 Megahertz profile, the Cologne-based company is now taking a step further in the laboratory tests. "By re-doubling the frequency spectrum for data transmission, we are near the two gigabit brands for the first time," Lepel says.
Cooperation with ZT
ZTE supports NetCologne as a technical partner in the strategic development of the existing FttB network (= Fibre to the Building). "Together with NetCologne, we continue to push the G.fast technology to their limits and create the ideal basis for future applications," said Sun Jie, Managing Director of ZTE Germany. "These ultra-high speeds are unique in a global comparison."
Precondition for G.fast
The G.fast technology will be available in the NetCologne network in the course of the year in 260,000 households. The prerequisite for this is that the respective building has a fiber optic connection from NetCologne. A further expansion of the G.fast network is planned in perspective.
