In 2016, G.fast looked very promising.
But only BT & Australia's nbn remain

"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.
Huawei's Eric Wang is the editor.
ADTRAN, ASSIA, AT&T, BT, Broadcom, Huawei, Intel, Nokia, Swisscom, & ZTE have promised to support the work.
The goal is a maximum aggregate net data rate per single line of 10 Gb/s and 5Gb/s. It will work on both twisted pair and Coax.
Telcos are supportive because DOCSIS 3.1 promises to reach 10 gigabits one day. They want to be ready. Adtran and Nokia/Alcatel are having some success selling to cablecos. When this works, I'm sure they will try to promote it.
25 years ago, the first DSLs were 1.5 & 6 megabits.
