Highlighting the new digital divide that need addressing in UK, speakers at the Westminster eForum said that around 10% of the UK will be kept out of superfast broadband in the next decade.
They felt that the £530m government fund earmarked to address the notspots was insufficient.
Telecom operator BT said that the target of EU to make accessible to all citizens speeds of minimum 30Mbps by 2020 were "impossible to achieve".
Japanese firm Fujitsu, which had said that it could create a fibre-to-the-home 1Gbps network for around 5 million users, within five years, is finding the going difficult in Wales, North Yorkshire and Cumbria.
In the Highlands and Islands, the company said that this project is not simply financially viable.
This point was also endorsed by UK operator BT, when Sean Williams, group director of strategy and policy at BT, said that current funding would reach only 90% of the UK.
Simon Towler, the head of spectrum, broadband and international ICT policy at the Department of Culture, Media and Sport (DCMS) said two things were needed to drive-up wireless speeds in Britain: "more spectrum, more masts or both".
He added, "We need to get on with this [4G] auction and do it as soon as possible."
