Tests by network specialist SIRODA comparing the data speeds of all five UK operators show that on average O2 had the fastest network over a 60-day period between October 2010 and January 2011, according to the operator.
SIRODA undertook 169 static test locations, measuring mobile data connection speeds at peak periods throughout the day.
O2 reported that the tests show that O2 offered the best data experience in 12 out of 13 cities. On average, web page access on the O2 network was delivered in 1.4 seconds, over three times quicker than the slowest operator.
Data performance was measured by testing the time to access a webpage and the speed of downloading a typical music file. Tests were conducted between 8am and 9pm Monday to Sunday, replicating genuine user patterns. Cities covered included London, Bristol, Edinburgh, Leeds, Liverpool, Newcastle and Sheffield.
