The technology leverages EE’s 2.6GHz spectrum and is said to deliver data speeds of up to 150Mbps.
It is available throughout most of central London, including Soho, the South Bank, Kensington and Shoreditch.
The UK operator plans to expand its LTE-A coverage to Greater London and a number of other UK cities in 2015, including Birmingham, Manchester and Liverpool.
“The UK is now back to being a world leader in mobile networks. Just two years since we were behind every developed market from the US to Japan, we’ve invested in innovation, driven competition and given people in London a mobile network that’s faster than almost any other in the world,” commented Olaf Swantee, EE’s CEO.
EE has 4G coverage across 300 cities and towns in the UK. It claims to have already surpassed its year-end target by signing up 6 million customers for the service.
