Ofcom has been forced to reopen its consultation into the re-farming of older 2G mobile phone spectrum from O2 and Vodafone for use by 3G services, such as 'Mobile Broadband'.

The regulator had hoped that the move would improve coverage while making wireless broadband services both cheaper and faster. Unfortunately both O2 and Vodafone naturally disagreed, sighting concerns over the technical and commercial impact of Ofcom's proposals.
