BT: is fast and we want it FASTER

UK telco lays out standards wish-list

BT has told a US broadband conference it's confident that will do what it says on the box – so long as ongoing standards work bears fruit.

However, The Register notes with interest that the dependencies highlighted by BT Wholesale CTO Colin Bannon are many.

As noted at LightReading, Bannon reckons is good for 300 Mbps at 350 metres, even with the “alpha” kit the carrier currently has its hands on.

Bannon told the Chicago Big Telecom event that there's a number of ways in which the standard can be improved, including increasing the bits per tone, a better noise floor, higher transmit power, bigger vectoring groups, and better frequency usage alongside VDSL.

Bannon told the conference that BT is “aggressively pursuing additional standards”. With a work list like that, turning the lab work into standards, the standards into silicon, silicon into products and products into deployments seems non-trivial to El Reg.

Even if the ITU's standards get updated to BT's wish-list at an astonishing pace, real-world deployment in many countries will also depend on carrier network rules.

For example, the rollout of VDSL2 in Australia is currently awaiting the Communications Alliance's network deployment standardisation effort. A standard with appropriate network rules would lag product announcements by at least a year. ®
