DT intends to test G.fast in 2014 and deploy it in 2015 WiWo reports. DT needs speed to counter cable, already offering twice DT's speed at the same price. Kabel Deutschland back in 2012 demonstrated 4.7 gigabit cable. KD's CTO, Lorentz Glatz, told me he was hopeful of reaching a gigabit in 2013 or 2014.
CTO Jacobfeuerborn, citing Alcatel, believes he will soon get 212 GHz G.fast chips that can go to a gigabit. Most others think 200-500 megabits far more likely for early G.fast. Few expect substantial deployment until 2016-2017. 400 megabit and higher speeds definitely require vectoring at 100 meters, which no one has demonstrated.
Jacobfeuerborn continues to tell journalists that DT will pass 24 million lines with vectored VDSL by 2016 but the rumor is that DT will stop at 12M. They will upgrade their ADSL lines to vectored VDSL but may leave existing VDSL lines at half the speed.
Perhaps more interesting is DT's home gateway that combines VDSL with LTE. DT intends to soon increase the speed of many cell sites to 600 megabits (shared) from the current 150 megabits. They bought 95 MHz of spectrum at auction and can look to easily pass 1 gig per cell in perhaps few years. Very rarely will those cells be congested, so some of that bandwidth can be diverted from mobile to upgrading the speed of home gateways. Keymile already has prototypes.
