Service is established through a combination of wired, wireless and satellite technologies. Depending on the plane, passengers can plug into a standard phone jack or connect via 802.11b. Either way, the connections feed directly to an in-plane bank of servers, which authenticate users and ensure payment has been made. Many planes also will come with electrical plugs so laptops won't have to run on batteries. For now, connecting through a jack likely will be more common. National air traffic authorities have to approve specific Wi-Fi products for in-flight use. Wireless users on Lufthansa's flights, for instance, have to use loaners from the airlines. Regulatory approval, however, will likely accelerate, Weisheit said. The in-flight servers then connect to satellites orbiting the equator. Connexion specially designed the antenna the airplanes use to connect, Weisheit said, and the company is working on a more high-powered version with Mitsubishi. "It is mechanically like the same technology that links terrestrial ATM machines," he said. "The difference for us is that our ATM machines are moving at 600 miles an hour." Connections to the satellite on the current system fade out north of Iceland, he said. The coming antennas will allow planes to maintain reception for planes on polar routes above Greenland. Weisheit and others also stated that the system is robust enough to not require in-flight information technology managers. The company is part of Boeing's overall effort, kicked off in 1996, to broaden its revenue base, according to company executives. Boeing formed Connexion in November 2000. Originally, it was targeted at providing service in the United States. American Airlines, Delta Air Lines and United Airlines were investors. The decline in air traffic after 11 September, 2002, however, forced these companies to drop their equity positions in Connexion, Weisheit said.
