Passengers will soon be able to make and receive mobile telephone calls

in-flight due to a system developed

by Honeywell, in collaboration

with AltoBridge. The Honeywell communication system uses AltoBridge software technology to provide this once prohibited

calling option.

AltoBridge states that its technology enables a full voice and text messaging service. Tests carried out on the software last August showed that Honeywell’s system does not interfere with the ground mobile telephone network or the aircraft’s navigation and communication unit. The on-board system directs the mobile telephones to their lowest power level.

The system will initially work with GSM mobile networks. AltoBridge will eventually integrate the Honeywell system with other mobile networks and wireless technologies. The call and message charges will be included in the subscriber’s regular telephone bill. The system will be available for installation later this year.

Hot on the heels of Honeywell, telecommunication companies Arinc and Telenor have jointly launched AeroMobile, a service that will enable airline, regional and business aircraft passengers to make cellular telephone calls whilst in the air.

The system was recently tested via a link up with Inmarsat’s satcom system, simulating the use of cellular telephones for voice calls and text messaging at 30,000 feet.

“We are bringing to market a fully-defined mobile service,” said Bernt Fanghol, vp of mobile connectivity, Telenor new business. “AeroMobile has the advantage of capturing

the earliest opportunities for passenger mobile services in

flight due to our developed

terrestrial infrastructure, establishing international roaming agreements, and thoroughly tested onboard satellite communications systems.”

Although AeroMobile is initially targeted at long-haul airline flights, the system will later be available for business aircraft. Gulfstream and Airbus have both also reported successful tests of cellular communication in recent months.
