As previously revealed to Pocket-lint, EE has started testing a new 4G LTE Advanced network in partnership with Huawei. It claims to offer speeds of up to 300Mbps, which it calls the fastest in the world, and it has switched on the service in the Tech City business area of London.

Customer trials will begin in early December, with offices in the area being able to access the mobile Wi-Fi service. Plans are to then expand its reach across London in 2014.

"Today is about introducing the next age of 4G mobile technology to the UK," said Olaf Swantee, who announced the switching on of the service at the Huawei Global Mobile Bradband Forum in London.

"The network we’re switching on today in Tech City is the first part of an infrastructure that can meet the future demands of increasingly data-hungry consumers and businesses, and enable completely new ways of doing business."

Huawei will introduce its first commercially available LTE-Advanced Mobile Wi-Fi units in the second quarter of 2014. These should capitalise on the potential 300Mbps speeds offered by the new network.
