Wireless Networks for Air Passenger Operations

Miles of hidden data cables connect the hundreds of check-in and boarding computers visible at a typical airport. When the airport needs to expand or remodel, much of this hardwired network must be ripped from the walls and ceilings and re-installed. It is a slow and costly process that is often repeated two or more times during a single construction project.

A wireless approach would clearly be preferable—simply transmit the needed data throughout the airport by radio. But the security of wireless systems has always been suspect, and following September 11, 2001, airport security became an overriding issue. This fact has prevented many large-scale deployments of wireless networking for passenger handling—until now.

ARINC has introduced a secure wireless network that meets the concerns of both airlines and aviation authorities. The new system is based on industry-standard equipment, using 128-bit data encryption augmented by a dynamic WEP (wired equivalent privacy) algorithm to protect the data. An advanced Cisco Systems Wireless Security Suite provides robust security enhancement with centralized, user-based authentication to guard against network intrusion.

The result is an intrusion-resistant network with data encryption superior to electronic banking systems.

The ARINC Secure Wireless Network was first deployed in December 2002 at Grantley Adams International Airport in Barbados. Over 100 check-in and boarding computers are using the network during the airport’s major expansion that will last until 2004. Six major airlines and aviation authorities approved the system, and airport management—which initiated the wireless project—is enthusiastic about its success. With wireless operation all the check-in and boarding counters can be moved as needed, wherever there is a power outlet.

The ARINC Secure Wireless Network is designed as an extension of ARINC’s MUSE^® technology, the industry’s most advanced common-use passenger system. The new web-enabled i MUSE™ passenger system allows airline personnel to work efficiently, with easy access to their corporate intranets, e-mail, and other productivity-enhancing business applications.
