The issue of radio frequencies is becoming a serious headache for the government and the regulator Ofcom in what would seem to be a straightforward plan to auction off the spare capacity in the spectrum, in order to provide better mobile broadband coverage.
The problem lies with Vodafone and O2, who suggest that this auction is unfair and may even take the plans to court for a decision.
The mobile operators believe that a fair division of the spectrum would be essential for the future of mobile broadband.
The problem with the spectrum is that it is too complex.
Ordinarily the sensible outcome would be to start again and divide the spectrum up in way that provided the best situation for all concerned, but as the government sold off sections of the spectrum this has caused the issues currently being seen.
