The US Federal Communications Commission has ended a proceeding that would have allowed mobile phone calls on airplanes, for now ending the possibility of phone conversations during flights.

The FCC announced it would not move forward with the proceeding. Public comments provided "insufficient technical information on whether the use of cellular phones onboard aircraft may cause harmful interference to terrestrial networks", the FCC said in an announcement.

After the FCC opened the inquiry in December 2004, the agency received thousands of comments from airline customers asking it not to approve mobile phone calls during flights. Many people said they didn't want to be subjected to their neighbours' phone conversations. Some mobile phone carriers also expressed concern that in-flight conversations would interfere with their on-ground networks, and the idea received mixed reviews from airlines.

However, the FCC left the possibility of in-flight phone calls open. Airlines, device manufacturers and wireless providers were still researching the use of phones and other electronic devices on flights, and the FCC found it would be premature to seek further comment at this point, the agency said.

It could reconsider the issue later if appropriate technical data wais available, the FCC said.

European airlines are gearing up to offer in-flight mobile phone service by the end of the year.

The FCC's action would have needed to be accompanied by a change in rules at the US Federal Aviation Administration.

Some airlines are experimenting with Wi-Fi service during flights. In November, AirCell announced it had received an FCC license to provide air-to-ground broadband service in airplanes.
