But with gigabit cable coming close, AT&T is pressing for a gigabit over DSL. Adtran, a major supplier to AT&T and Deutsche Telekom, has proven that G.fast can easily exceed a gigabit downstream by bonding two lines. It's just a lab demonstration for now without a timetable for field trials. 

G.fast vectoring and pre-coding require serious processing power to keep up with the high speeds. Bonding for even higher speeds is a challenge, but Adtran CTO Kevin Schneider doesn't see any obstacles that will prevent practical deployment. 

ITU's early press release promised a gigabit from G.fast but real speeds are currently 400-700 megabits. Cablecos Videotron and Suddenlink are beginning deployments of a gigabit (shared) over DOCSIS 3.0. Comcast and Cox have a prohibitively expensive ($700+) fiber gigabit home that today is a pr stunt. Both tell me that they expect DOCSIS 3.1 to inexpensively achieve a gigabit by late 2016.

The business side hasn't decided how to price the high speeds. A gigabit over DOCSIS 3.1 only costs between $1 and $3/month more than a 10 megabit cable line. With competition weak, I expect a much higher consumer price, however. Sharing cable works remarkably well; a shared gigabit will deliver 500+ megabits to any home that needs it 95+% of the time. 

Paul Spruyt of Alcatel predicted G.fast bonding in an interview almost two years ago.
