A 4G tour in London

Armed with a pint of London Pride and a 26 Mbps uplink, Trefor was set for the challenge to see if O2's 4G connection could upload a large video file to YouTube before he had finished his pint. Well, Trefor drinks fast, but O2's 4G uplink was no slouch either and both managed to complete their respective tasks in under five minutes.

In fact, Trefor ran four simultaneous BBC iPlayer streams over the O2 4G network just for fun, demonstrating that, during the trial at least, there is plenty of available bandwidth. He has posted a video of this on his blog.
