Ofcom has published a proposal to liberalise all UK mobile licences in the 900MHz, 1800MHz and 2100MHz bands. This would let network operators deploy 4G technology on frequencies that had originally just been licensed for 2G or 3G services.

In addition, it’s proposing that base stations would be allowed to transmit at increased power on 900MHz frequencies.
