New AeroMobile™ Inflight Phone System Will Use Airborne Servers from VT Miltope

April 5, 2005

Annapolis, Maryland, USA and Oslo, Norway—ARINC Incorporated and Telenor today revealed the last major technical element of their planned mobile phone service for airline passengers. The two companies have chosen a high-performance, ruggedized communications server from VT Miltope as the on-board hub for passenger communications when they launch their AeroMobile™ service this year.

Miltope is a leading maker of communications hardware for military and commercial uses, including servers for multimedia, communications, and data applications. The new Miltope Airborne Telephony Server (ATS) is ideally suited to bandwidth-intensive tasks such as shared delivery of mobile cellular, E-mail, Internet, and IFE services in the aircraft cabin.

“ARINC selected the Miltope ATS for its superior performance and expansion capability,” stated John Little, ARINC Technical Director, Europe, Middle East, and Africa. “The ATS will efficiently handle AeroMobile service now, and can easily handle Internet and data services in the future with Inmarsat Swift64SM or SwiftBroadbandSM SATCOM upgrades.”

As the hub of AeroMobile service, the Miltope ATS will run industry-standard Altobridge AM Gateway PlatformTM and custom AeroMobile software. The ATS manages the onboard picocell/antenna system for GSM connectivity within the cabin, and interfaces to classic SATCOM avionics either directly or through a Cabin Telecommunications Unit.

A subsidiary of Vision Technologies Systems, VT Miltope specializes in design, development, and manufacture of computers, peripherals, and networking equipment for rugged applications in both commercial and military markets. Commercial airborne customers benefit from VT Miltope's long involvement in military applications where reliability under demanding environmental conditions is paramount. VT Miltope's airborne data management and communication products include data and video servers, wireless access points, printers, in-flight workstations, laptop computers, and mass memory storage.
