BT to Lean on to Boost High Speed Access to 500 Mbps

BT plans to boost high speed access to as much as 500 Mbps, to most U.K. homes, within a decade, with fiber to home gigabit service also being made available.

By about 2020, BT expects to have boosted speeds to “a few hundred megabits per second to millions of homes and businesses by 2020,” BT says.

Speeds will then increase to around 500 Mbps as the new “” implementation of digital subscriber line technology improves. deployment will start in late 2016 or early 2017, BT now believes.

Since 1998, DSL speeds have grown by two orders of magnitude (100 times), so long as copper drops are short enough. In essence, that is the same principle used by cable TV hybrid fiber coax networks, which also combine fiber backbones with copper drop media.

If drop lengths are short enough (less than about 300 feet), speeds to 1 Gbps are theoretically possible. That implies a deployment of fiber almost to the premises. In urban areas, that might mean fiber to a cluster of two detached houses, for example. is the latest implementation of a technology many observers, early on, had believed would be quite problematic.
