Aircell Prepares for 2008 Launch of New Air-to-ground Broadband System for Business Aviation September 24, 2007 ATLANTA, GA [NBAA Annual Meeting & Convention] – September 24, 2007 – On the heels of Aircell’s milestone partnership announcements with American Airlines and Virgin America, the company today released further details about Aircell broadband for the business aviation industry. Aircell, recently named one of the top mobile broadband companies by FierceBroadbandWireless, is set to launch Aircell broadband for Business Aviation, its exclusive new high-speed, air-to-ground data system in 2008. “As Aircell’s broadband launch for Business Aviation approaches, the company is working to fulfill the long-standing, unmet needs of business aircraft travelers across the country,” said Jack W. Blumenstein, Aircell President & CEO. “With Aircell’s new broadband service, business aircraft travelers will soon have the option to connect using their own Wi-Fi laptops, PDA’s and dual-mode Smartphones in the cabin – at broadband speeds – greatly transforming their travel experience.” The Aircell broadband link will be a modular option available exclusively to business aircraft equipped with the Aircell Axxess™ cabin system. The Aircell broadband equipment will include a single broadband LRU that weighs less than 15 lbs and connects to Aircell Axxess via an integrated Ethernet port. With Aircell broadband installed, passengers will log onto the Aircell Axxess 802.11b/g “hotspot” and experience broadband connection as they do in their home, coffee shop or small office. These speeds will easily support full-scale Internet surfing, e-mail with attachments and corporate VPN access. At launch, the new broadband system will provide full, seamless coverage in the U.S. – from coast to coast and border to border. Service in Canada, Mexico and the Caribbean is planned to follow. The system will automatically transition between ground stations, providing uninterrupted service as the aircraft moves across the country. For business aviation broadband equipment, Aircell will begin taking orders in April 2008 and plans to make deliveries in the third quarter of 2008. The Aircell broadband system will operate over the exclusive, dedicated air-to-ground frequencies awarded to Aircell in a 2006 Federal Communications Commission (FCC) spectrum auction. Pricing and additional technical specifications will be announced in the near future.
