BT will have upgraded 60 per cent of the telephone exchanges in Sheffield to support its 21st Century Network (21CN) by the end of the month.
The announcement means that soon over half of the addresses in the Steel City will have the potential to receive broadband speeds of up to 20Mb.
Work will involve the upgrading of 117,000 lines and BT regional director John Anderson has explained that the improvements will take ADSL broadband services in the area to a new level.
He told the Sheffield Telegraph: "Sheffield is one of the first major communities in the UK to achieve this level of coverage.
"It will play a major role in helping Sheffield and the region as a whole attract and retain inward investment."
Among the internet features which are expected to be enhanced as a result of the project are voice, data and on-demand video services.
