Ofcom has allocated 800MHz and 2.6GHz spectrum to the five winners of the recent 4G auction.
BT, Three, Vodafone, O2 and EE have received their radio spectrum licences, allowing the firms to move towards their respective service launches.
This comes after the completion of the final assignment stage of the auction.
The winning bidders were given the opportunity to top up their bids in order to secure preferred locations in the frequency bands.
BT (£15.1 million) and Vodafone (£12.1 million) both took the opportunity to do so, increasing the overall value of the spectrum auction to £2.37 billion.
The winning bidders are now expected to launch 4G mobile services in the second quarter of 2013.
However, BT said last week that it has no plans to construct a mobile broadband network - instead its 4G spectrum will be used to support existing Wi-Fi and telecoms services.
