Ther are plans that will allow airlines to offer mobile services on UK registered aircraft.

This decision means that mobiles could be used once a plane has reached an altitude of 3,000m or more.

Airlines keen to offer the services must still satisfy other regulators.

Service charge

The decision to offer the services now falls to individual airlines. However, there are other regulatory hurdles to overcome before the technology is considered to be fully approved.

The European Aviation Safety Agency needs to approve any hardware that would be installed in aircraft to ensure that it did not interfere with other flight systems.

How does the system work?

In addition, said a spokesman for the UK's Civil Aviation Authority (CAA), airlines would need to develop operating procedures to ensure cabin crew were trained in the proper use of the systems.

The spokesman said the CAA knew many airlines had expressed interest in offering such services but added: "None have formally approached us yet."

"It's down to the airlines to decide whether they want to fit the systems then they would have to get approval for that," he said.

The plan is to install small mobile phone base stations, called pico cells, in aircraft that will be switched on after take-off. The base station generates a bubble of coverage in and around the aircraft.

Calls made via the pico cell will be routed to terrestrial networks via satellite link. Across Europe radio spectrum has been set aside for the technology.

The services could stop working once aircraft leave European airspace.

Initially, only second generation networks will be offered but growing interest would mean that third generation, or 3G, services would follow later, said Ofcom.

The cost of making a mobile phone call from a plane will be higher than making one from the ground.
