EE's 4G LTE network is now live in 11 UK cities, promising users download and upload speeds five times faster than 3G, according to the company. But can it deliver on its promises - and are those speeds possible indoors as well as out?
To try and get a fair representation of speeds in different parts of the capital, I visited a number of stations in the north, south, east and west of the city.
To carry out the test I used a Samsung Series 5 Slate running Windows 8, a Huawei E589 4G Mobile Wi-Fi unit, and the website Speedtest.net.
Over the course of the day I visited Shepherd's Bush, Oxford Circus, Tech City, Canary Wharf, Clapham North and Newington Green. You can click on any of the markers below for a breakdown of the speeds, or click on the link below for a full-size version of the map.

Check out the following pages for a first-hand take on how the new network performed.
If you are an EE 4G customer and live in London, get in touch with your speed test results and we'll add it to the map.
As you might expect, the outdoor locations largely saw better 4G coverage for the Mi-Fi unit and mostly delivered faster download and upload speeds than indoors.
However, there were a number of examples where that wasn't the case - where upload speed was faster than the download, or where indoor speeds seemed better than outdoor.
For example, the image above shows the results for Old Street, Shoreditch - home to Tech City. The outdoor test showed results of around 15Mbps up and downstream, and a ping time of 41ms.
The indoor test, performed about 20 feet away from the outdoor test, returned download speeds of around 9.5Mbps and upload speeds of 2.36Mbps. Despite the decrease in reception and speeds, the ping result was actually faster than outdoors, at 26ms; this was also the case in some of the other tests in multiple locations that returned lower indoor speeds than outdoor.
