UK 4G MOBILE NETWORK EE will bring 4G to 27 more cities in the UK by this summer, including Blackpool, Colchester and Woking.
The firm's 4G network has been live since November 2012 and has gradually been extended over time as it seeks to capitalise on its head start over rivals O2 and Vodafone.
The new locations will be live by June 2013, around the same time as its rivals should be bringing their services to market, with cities including Huddersfield, Leatherhead, Maidstone and Oldham also coming online.
EE also revealed that a number of high profile business customers are using its network including Microsoft, Sony and Gatwick Airport, as well as estate agents Foxtons, taxi firm Addison Lee and food sellers Morrisons.
Microsoft is said to be using 4G for its mobile workforce, Foxtons to allow agents to update its property database remotely and Addison Lee is trialing it to offer in-car internet services.
"To see UK businesses already benefitting from 4G after such a short time is great news," said EE CEO Olaf Swantee.
"Demand from small, medium, large and public sector organisations across the nation has been very positive since we launched 4GEE."
The firm made business use one of the core focus areas of its 4G trials before the network went live, as it sees the business market as key for 4G uptake by enabling better remote working and data access.
EE said late last year that customers were receiving speeds of around 6Mbit/s on average, and as high as 30Mbit/s in some locations, far higher than typical 3G connection speeds.
Auctions for new 4G spectrum are taking place behind closed doors with the winning bidders likely to be revealed by March and networks live this summer. µ
