Communications regulator Ofcom has unveiled new proposals for the wider delivery of 4G over radio spectrum.
According to the organisation, superfast mobile broadband services should be delivered over the 900 MHz, 1800 MHz and 2100 MHz radio spectrum bands.
Currently, EE is the only provider able to deliver through the 1800MHz spectrum, which prompted rivals Vodafone and Three UK to request that Ofcom cut the red tape preventing them from gaining spectrum licences.
In a statement, Ofcom said it is proposing "liberalising" all mobile licences in the three bands to permit the deployment of 4G services, which would specifically pertain to Three UK in the case of 210 MHz and Vodafone in each of the 900MHz, 1800MHz and 2100MHz bands.
"This will align the permitted technologies across all mobile spectrum licences, including the existing licences at 900 MHz, 1800 MHz and 2100 MHz and the licences to be awarded by auction in the 800 MHz and 2.6 GHz bands," the regulator added.
Further to the 4G requests, O2 and Vodafone have asked to increase their maximum permitted base station transmit power at 900MHz by decibels in order to benefit their 3G offerings.
