The UK does not need universal fibre-to-the-premises (FTTP) broadband coverage, according to telecoms giant BT.
Sean Williams, Group Strategy Director at BT, claimed that extra performance capacity can be squeezed out of existing copper and fibre-to-the-cabinet (FTTC) technology.
He said FTTP costs five times as much to deploy as FTTC, as reports by ZD Net.
"Furthermore there is no business case to support it," Mr Williams added.
"Technological developments mean there is no need for it. FTTC is a good solution for medium and long term."
Speaking at a House of Lords Select Committee meeting, he claimed FTTC is "far from being at its limit" and it will be possible to deliver faster speeds using the technology.
"Once you put an 80Mbps FTTC service into the premises the broadband network is no longer the speed bottleneck," Mr Williams noted.
"The home Wi-Fi or devices can't cope with the speeds, or at the other end, the servers serving communications can't deliver the speed."
BT is currently investing £2.5 billion upgrading its telecoms infrastructure with fibre cables, in order to deliver faster download and upload speeds to homes and businesses.
The broadband provider - currently upgrading telephone exchanges across Britain - is aiming to equip two-thirds of the UK with super-fast services by 2014.
But despite the rollout of fibre technology, Mr Williams said BT is continuing to improve its existing copper broadband networks.
"We still invest in them and we still connect households to the copper network," he added.
"[BT] will continue to invest in fibre and copper networks for the foreseeable future. Mass rollout of super-fast broadband is the work of the next decade, I suppose."
