Mobile broadband users on average receive speeds of less than 1Mbps, says Epitiro.

A study by the research group revealed that on average users receive just 24 percent of the advertised download speed, and on average mobile broadband is 34 percent slower than the average ADSL connection.

The research highlighted that at 3am, the average connection increased to 1.8Mbps, indicating that slow speeds can be blammed on high numbers of users all trying to get online.

"This exhaustive study confirms the general consensus that mobile broadband services are functional and, while currently slower in practice than their fixed line competition, continually improving," says Gavin Johns, CEO of Epitiro.

"That we recorded a few measurements at relatively higher speeds is confirmation that mobile broadband technology is capable of much more."
