Ofcom expects long-term evolution technology to be in use in the UK by 2014, it has been announced.
Ed Richards, Chief Executive of the media regulator, said the super-fast 800MHz and 2.6GHz mobile broadband spectrum would be released towards the end of 2013.
The 800MHz will be reclaimed from analogue television to enable mobile broadband providers to deliver faster download speeds to their subscribers.
Mr Richards said that so long as parliament provides the necessary statutory backing, by approving draft legislation due before it in the coming weeks, Ofcom will be able to "move rapidly" to liberalise the 900Mhz and 1,800Mhz spectrum.
"It is clear that we are talking about a very significant step forward - not only the most significant release since the 3G auction in 2001 but spectrum which is the raw material that will fuel an explosion in next-generation mobile broadband," he added, as reported by ISPreview.co.uk.
"For new innovation, for widening choice, for developing new services and for delivering high speed mobile broadband, this is an essential ingredient - with companies and consumers therefore sharing a common interest in making progress as early as possible."
However, Informa Telecoms & Media has warned this week that UK LTE technology may have to wait until 2015 at the earliest due to economic pressures.
