BT, the UK telecommunications group, is considering the case for an
ultra-fast broadband network that could deliver internet download speeds of
up to 50 megabits per second.
Sir Christopher Bland, the BT chairman who stands down in September, said
the company was looking at whether to install fibre optic cable as far as
the street kerb, where BT phone line cabinets are found.
The roll-out of fibre relatively close to homes and businesses could deliver
maximum broadband download speeds of 40-50mbps, according to BT.
This compares with the existing upper limit of 8mbps that is available from
most telecoms companies.
Investors are nervous about BT making any commitment to an ultra-fast
broadband network because of the likely capital expenditure involved. Some
analysts have estimated the cost at £4bn.
BT has repeatedly said there is no economic case for taking fibre all the
way to homes except on greenfield sites because of the cost involved.
But Sir Christopher said BT's thinking had advanced "quite far" on the case
for fibre to the kerb.
"That is the more likely development going forward," he said, while
stressing no decision had been taken to go ahead with fibre to the kerb.
BT is planning to offer broadband speeds of up to 24mbps from next year, as
it rolls out a £10bn "backbone" network and introduces technology known as
ADSL2+.
Sir Christopher questioned whether "most consumers" would need broadband
speeds of more than 16 or 24 mbps, but accepted some businesses might do.
The Broadband Stakeholder Group, a government advisory panel, claimed in
April that the BT network would be too slow to meet the demands of the most
demanding households and businesses by 2012.
Enders Analysis, a research firm, estimates that less than a third of
households will enjoy broadband speeds of more than 20mbps with BT's ADSL2+
technology. This is partly because broadband speeds are dependent on the
length of copper landlines running from BT phone exchanges to homes.
The Broadband Stakeholder Group said ministers and regulators had two years
to find ways to encourage investment in high-speed broadband or UK
competitiveness would suffer.
BT is considering the case for inserting fibre between its exchanges and the
phone cabinets found on the street kerb, and introducing VDSL2 technology.
Copper landlines would run from the cabinets to homes.
Sir Christopher said any fibre roll-out would be in "selected areas".
Analysts said BT would focus on towns and cities.
