As debate continues on the future of fibre-optic broadband, it has been suggested that the business case for investment is not compelling.
In a recent article in the Times, media analyst Dan Sabbagh asserted that the necessary infrastructural upgrades - which could cost as much as £10 billion - would deliver a business return for BT.
Conversely, a recent Broadband Stakeholders Group report has suggested Britain is losing out on £16 billion in business investments because of a lack of high-speed broadband services.
Mr Sabbagh noted that fibre-optic broadband does not necessarily bring greater productivity and added that at the current time, existing broadband services are adequate for most needs.
"Yet, bottlenecks are starting to emerge in the UK, particularly on the congested highways from the exchange to the trunk network," he commented.
The popularity of high-bandwidth services such as video streaming and music downloads is putting significant strain on the network, with some providers claiming the internet will come to a standstill in the future.
