Ofcom has given the UK's mobile networks the go-ahead to trade spectrums in a bid to create more reliable mobile broadband services.

The watchdog said that for the past two decades, mobile phone companies have acquired blocks of licensed spectrum.

"Not all operators hold the same amount of spectrum, and the level of demand for mobile services also differs from area to area," Ofcom said.

However, now the networks will be allowed to trade the 900 MHz, 1800 MHz and 2100 MHz spectrums to ensure better coverage in the areas where demand is high. Ofcom also believes the move will create "greater opportunity to use it [mobile spectrums] more efficiently".

"This... comes in response to the fast pace of change and innovation taking place in the mobile communications sector, which is placing increased demands on spectrum," said Ofcom chief executive Ed Richards.

"One important way of meeting this demand is making the acquisition of spectrum as flexible as possible."
