BT Openreach announced that a further 66 exchanges that are next in line for super fast fibre-based broadband.
The expanded list of exchanges are dotted across the UK and between them, BT said, over a million new premises would gain access to the network. However most are not expected to come online until 2012.
BT's wholesale broadband arm also said that a milestone of five million premesis covered by the fibre infrastructure would be passed later this month. BT also announced a trial of wireless equipment operating in the so-called 'whitespaces' spectrum freed up by the digital TV switchover.
"Being able to bring faster broadband speeds within reach of more than five million premises is a significant milestone and we are well on our way to passing 10 million in 2012 and two-thirds of UK premises by the end of 2015," said BT Openreach boss Liv Garfield.
BT published the details of 'where and when' the fibre network would appear on the firm's website here.
