4G services are planned to be available in the UK during the first half of 2013.
Ofcom says that significant strides are being made to deliver 4G mobile services throughout the UK soon.
The regulator received complaints from major UK mobile operators after Ofcom gave early regulatory approval to an application from Everything Everywhere to use its spectrum.
According to Everything Everywhere, its 4G services will be available on 30 October this year in 10 cities. Their 4G service will then roll out to 16 cities by the end of the year.
"The actions we have taken with industry and government avoids the risk of significant delay and is tremendous news for consumers who might otherwise have waited a considerable period for the next generation of mobile broadband services," said Ed Richards, Ofcom chief executive.
The spectrum will be cleared and ready 4G mobile services for the UK five months ahead of schedule.
Ofcom plans to start the auction process to release the spectrum at the end of 2012 and for bidding to start at the beginning of 2013.
"Ofcom's objective has always been to release the spectrum as early as possible and we remain focused on starting the auction by the end of the year," added Richards.
Requirements specify that mobile broadband services will be available to consumers indoors as well as 98% of people located in villages, towns and cities in the UK.
