O2's London 4G Trial Reveals 150Mbps Speeds

O2 has just announced the results of a London-based 4G LTE trial which involved 25 base stations and 1,000 smartphone owning participants.

The announcement comes as London switched off analogue TV services, freeing up more potential spectrum which could be used by network operators. And they're going to need all they can get, looking at smartphone growth projection figures, and the increasing prevalence of bandwidth intensive activities such as video streaming.

O2 said: "Switching over the UK's analogue TV signal and replacing it with a digital signal will free up the airwaves to make way for super-fast internet access, known as 4G ... O2 has been running the first and largest urban 4G network trial in the UK since December 2011."

O2 declared the London trial, which took place over an area of approximately 40 square kilometres, a success.

The network stated that it managed to record a headline speed of 150Mbps during testing, and noted that a 40Mb file could be downloaded in just a few seconds. Naturally, real world performance won't be quite as sharp as those figures.

Everything would seem to be in order with regards to beginning the roll out of 4G services in the UK for O2, the main stumbling block now being the ins-and-outs of the spectrum auction process itself, which is still being heavily debated by operators and Ofcom.
