Consumers in Cardiff and Taffs Well have gained access to broadband speeds of up to 40Mb following BT upgrades in south Wales.
The internet service provider has carried out improvement work to a local network serving up to 16,000 homes and businesses in the area, as part of a £1.5 billion investment in the UK's internet infrastructure.
Fibre-to-the-cabinet broadband has been made available to those living and working in the selected areas, quintupling download speeds for many users.
Ann Beynon, BT Director for Wales, said the principality was "at the forefront of the broadband revolution in the UK".
She commented: "The upgrading of the network and BT exchanges in central Cardiff and Taffs Well is the latest vital step in ensuring that Wales benefits from exciting, leading-edge technology capable of delivering a wide range of innovative new applications."
However, according to the Federation of Small Businesses, there is a continuing need for investment in broadband services for rural areas of Wales, where companies and households are blighted by poor connectivity and low download speeds.
