The government should raise its broadband universal service commitment to 10Mb, it has been claimed.
Steve Unger, Ofcom's Group Strategy Director, said it is no longer satisfactory for the coalition to aim for nationwide 2Mb broadband.
The government is seeking to achieve this level of coverage by 2015, while offering the benefits of super-fast broadband to 90 per cent of the population.
But Mr Unger offered the view that the 2Mb target is out of date.
He said the current universal service commitment was determined by "a range of factors", based upon what was historically deemed necessary to have a basic internet experience.
However, in 2013 - with ever more services delivered online, and higher customer expectations - this is no longer applicable.
Mr Unger claimed the broadband speeds required for a simple connection will continue to evolve over time.
So even if the government was to raise its commitment to 10Mb, these speeds may be inadequate come the end of the decade.
