EE, no doubt acutely aware of the incoming competition in the market in the coming months, has taken steps to boost its network, promising double the speed and capacity of its 4G. The arrival of double-speed 4G enables 'lab speeds' of 130Mbps, but will boost headline 4G speeds to 80Mbps plus, and double the average speeds for 4GEE customers to more than 20Mbps. That's down to the network doubling the amount of 1800MHz spectrum bandwidth dedicated to 4G, from 10MHz to 20MHz, increasing capacity and those speeds.The 'turbocharged' 4G will roll out to ten existing 4G cities by summer – Birmingham, Bristol, Cardiff, Edinburgh, Glasgow, Leeds, Liverpool, London, Manchester and Sheffield and once switched on, will be available in those cities within existing plans to new and current 4GEE customers on all 4G smartphones, tablets and dongles.Olaf Swantee, Chief Executive Officer, EE, said: 'We are ensuring that the UK remains at the forefront of the digital revolution. Having already pioneered 4G here, we're now advancing the country's infrastructure again with an even faster, even higher-capacity network, and at no extra cost to our customers.''Since we launched 4G, we've seen a huge shift in the way people are using mobile. Video already accounts for 24% of all traffic on our 4G network – that's significantly more than on 3G. Maps, mobile commerce, sat-nav tools and cloud services are all seeing a similar rise. Mobile users in the UK have a huge appetite for data-rich applications, and this will only grow as people become more familiar with and reliant upon next generation technologies and services. Our double speed 4G network will provide developers with the quality and speeds needed to develop the next wave of killer 4G apps. Whatever innovations they come up with, we're ready.'
