New technology that could make it easier for remote communities to get faster internet is being tested in the Western Isles.

BT says the majority of the 20 households involved in the trial in North Tolsta on Lewis have had "significant increases" in the speed of their broadband.

Internet speeds tend to drop when connections are made over long distances but BT's Long Reach VDSL pilot involves technology which can overcome the problem.

Slow internet can negatively affect communities in the Highlands and Islands and Audit Scotland recently described the nationwide roll-out of superfast broadband as "challenging".

BT Openreach chief executive Clive Selley said: "Getting faster speeds to rural communities is one of my biggest priorities so testing new solutions in the field like this is a crucial part of that process.

"This is a British innovation story and our world class labs are pioneering a technology which could improve speeds for thousands of homes and businesses across Scotland and the rest of the UK - particularly those connected by long lines that are between 1.5km and 3.5km away from the cabinet."

Mr Sell"Our lab tests prove that Long Reach VDSL has the potential to significantly boost speeds over such lines, which are typically found in remote parts of the UK.

"I'm pleased that North Tolsta is the first Long Reach VDSL test site in Scotland and the early results are very positive.

"This trial will provide engineers with more information on how the new technology works in one of the UK's remotest locations."
