Known as LTE (Long Term Evolution), the 4G mobile broadband test was carried by Chinese wireless company Huawei at O2's headquarters in Slough, just outside of London.
Even more impressive is that later versions of 4G could hit speeds of up to 1Gbps – almost inconceivable considering we're currently stuck with limits of between 3.6Mbps and 7.2Mbps.
Of course as the bandwidth is shared between lots of customers we don't even hit these numbers with the current offering, so the figures for 4G are certainly to be taken with a sizeable pinch of salt.
Still, it should still be faster than what we have at the moment, and with an expected a roll out beginning in late 2010, it's not like it's some crazy future tech either.
We'll keep you up to date on all this as it happens, so keep it locked to Stuff.tv for all the speedy details as we get them.
