SEATTLE, April 28 (Reuters) - AT&T Inc and Honeywell International Inc said on Monday that they have agreed to launch a high-speed 4G LTE-based in-flight connectivity service for airlines and passengers in commercial, business and general aviation in the U.S.
The system would use air-to-ground cell technology, drawing on AT&T's network and using Honeywell technology on the aircraft, officials from Honeywell said in an interview.
Gogo Inc currently provides an air-to-ground technology that is available on about 80 percent of wired commercial aircraft in the U.S.
Honeywell said the AT&T system would have greater speed and bandwidth than do existing systems and would begin operating in 2015 in the United States.
Gogo shares fell 14 percent in after-market trading, following the announcement.
