Mobile broadband does not yet look like being a viable successor to fixed-line services, according to one expert.

While several fibre-optic cable broadband projects are up-and-running around the country, 4G mobile broadband is still being put forward as a potential successor to fixed-line.

However, judging on the current performance of 3G broadband, Alex Salter of broadband website SamKnows, has suggested that the technology is nowhere near being ready to take over from fixed-line entirely.

He told the BBC: "Mobile broadband is not the replacement for fixed line broadband that everyone once thought.

"There are issues with the network and services drop off the more people who use it."

Vodafone is one of the operators pushing the capabilities of mobile broadband, having just completed successful trials of a 20Mb offering.
