The phone giant EE, Britain's first operator of a super-fast 4G mobile service, has vowed to double the speed of its network by the summer just as rivals such as O2 and Vodafone finally launch their own services.
Olaf Swantee, chief executive, said that EE's enhanced 4G service will be 20 megabits per second or 10 times faster than existing 3G offered by all the main operators. It should mean speeds comparable to fixed-line broadband, making it easier to watch a high-definition TV show or have a video conference.
EE is doubling 4G speeds by using its previous 2G spectrum. Some analysts have doubts about the 4G launch, but Mr Swantee hopes to win a million 4G customers by the end of 2013.
