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.

2,000 homes connecting in coming weeks. Everyone in the industry is watching BT's trial of G.fast - even if BT is now deploying "G.halffast." Gavin Patterson. CEO of BT is telling investors and regulators BT will rapidly deploy 10M+ lines. In 2014, BT tested G.fast technology at 600 and even 700 megabits down on very short loops. This February, Patterson was still talking 500 megabits. Those speeds required going to many of Britain's 4,000,000 "distribution points."
This spring, they reduced the targeted speeds to 250 correction 10/10 330 megabits, going to existing street cabinets instead of the distribution points. The money men decided the higher speeds weren't worth the extra cost. That's risky - cable in England will soon be at a gigabit. Many BT customers - 5-20% - will get much slower speeds, depending on how many cabinets they ultimately deploy.
Optimists - including the chip vendors - think tens of thousands of lines will ship worldwide soon and mass production begin early next year. Others - including sensible people at BT - don't want to commit until they have the results from thousands of lines in the field.
AT&T plans similar, as do some of the smaller Europeans.
Thanks to Guy Daniels of TelecomTV for the picture and catching the speed limit in the press release. I had missed it.
Here's the release.
