Public sector broadband investment is needed to complement the network development work being carried out by private internet service providers, it has been claimed.
According to Raymond O'Hare, chairman of the Institute of Scotland and the former Scottish head of Microsoft, commercial organisations such as BT cannot be relied upon alone to upgrade the UK's entire internet infrastructure.
Last week, BT announced that it would be investing a further £1 billion in its telephone exchange upgrade programme, in addition to the £1.5 billion already being spent.
However, as reported by the Scotsman, Mr O'Hare believes partnership between the public and private sectors is needed to provide high-speed broadband across the UK.
"Only then will Scotland attract new and highly lucrative business to its shores," he said.
"The bottom line is that we must not be constrained by the unambitious targets set out in the latest Digital Britain report."
