(Telecompaper) Prime Minister David Cameron has officially launched a partnership between EE and Tech City in East London, which is home to over 1,300 tech start-ups, small businesses and entrepreneurs. EE will prioritise Tech City for all of its new network innovations. Over the last six months, the operator has invested GBP 3.6 million to boost existing network coverage in Tech City. The area was the first in the UK to get double-speed 4G in July, and is the launch pad for the EE's 300Mbps mobile network, which is officially switched on and made available to businesses from 06 December. EE CEO Olaf Swantee said the 300 Mbps 4G service would be rolled out commercially in 2014 to businesses across the UK.
