BT has confirmed it will trial the use of white space technology in Cornwall to gain better insights into how it could be used to deliver internet access to those in remote regions.
The firm has already trialled the technology on the Isle of Bute in Scotland, providing around a dozen homes with internet access where previously none was available.
BT will now run the trial in Cornwall in the same area as its previous 4G trials with Everything Everywhere.
BT said that by running the trial in the same area as the LTE trials it could compare the two services to see which is a more viable system for remote regions.
"The Bute trial has generated some encouraging results and so it is time to extend it to a larger audience and to test the technology further," it said.
"The new trial will take place in the same area in which we have been testing LTE. Tests produced encouraging results and so the new trial will give us the chance to make a direct comparison between the two technologies."
It also said it would help it consider how it could turn the use of white space technology into a commercial service.
White space technology works by exploiting the unused segments of digital TV signals, which vary geographically, to broadcast signals in areas where broadband is either non-existent or below 2Mbit/s.
The government wants 90 per cent of the UK's population to have access to 25Mbit/s speeds or above by 2015, with remote regions the most unlikely to get wired connections.
The use of innovative technologies like white space service is seen as a key way of reaching remote locations.
BT is already working in Cornwall to bring superfast broadband connections to the county, using a combination of its own funding and a grant from the European Commission.
