Everything Everywhere - the parent company of Orange and T-Mobile in the UK - says it is ready to launch super-fast mobile broadband services.
The firm is seeking Ofcom approval to introduce commercial 4G services using the 1,800MHz spectrum band.
The media regulator has been instructed to allow the use of long-term evolution technology through this frequency, and Everything Everywhere is requesting permission to do so.
Olaf Swantee, Chief Executive of Everything Everywhere, said the firm's vision is to launch 4G for Britain as soon as possible.
"The roll out of 3.5G HSPA+ and our 4G trials across Britain are major steps towards delivering on that promise," he stated.
"The integration of the Orange and T-Mobile networks has already given our customers the widest 3G coverage in the UK - and I am pleased to say that with our advanced HSPA+ roll out they will also benefit from the fastest."
Mr Swantee added that, subject to regulatory approval, Everything Everywhere will be in a position to begin the rollout of 4G before the end of the year.
"There is a great opportunity for the UK to have the 21st Century network that it so deserves, putting the nation on a level playing field with other parts of Europe, the USA and Asia," he stated.
