Super-fast broadband is expected to be available in Caerphilly town by the end of this summer, according to BT.
The telecommunications firm is currently rolling out a fibre-based broadband network that should give download speeds of up to 40 megabits per second (Mbps).
The fastest speeds currently available are around 8Mbps.
Cardiff and Taffs Well are among the first places in the UK to access super-fast broadband from BT after an upgrade at a local exchange.
BT has said that Caerphilly is one of the places that will receive the upgrade in coming months.
Ann Beynon, BT director for Wales, said: “Once again, Wales is at the forefront of the broadband revolution in the UK.
“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, such as high definition video conferencing and 3D television over broadband.”
