FREMONT, Calif.--(BUSINESS WIRE)--Dec. 3, 2002

Insignia Provides High Performance Java(TM) 2, Micro Edition

(J2ME(TM)) Software for HNS-designed Thuraya

Mobile Satellite Phones

Insignia Solutions(R) (Nasdaq:INSG)

The phone's dual capabilities enable customers to access GSM services wherever available, and automatically switch to satellite mode whenever outside of local terrestrial reach. This is the first HNS phone to deploy Java technology.

Insignia's handset provisioning software will enable HNS mobile phones to download and run Java(TM) 2, Micro Edition (J2ME(TM))-based mobile services, including personal information management software (PIMS), address books, games, business-to-business applications, and messaging.

"Hughes Network Systems is the global market leader in broadband satellite networks, and is the supplier of gateways and handsets to the Thuraya mobile satellite service, whose coverage reaches more than a third of the world's population," commented Mark McMillan, president of Insignia. "This relationship reinforces the importance of Insignia's Java-enabling software as fundamental to the successful adoption of next generation mobile devices and widespread deployment of new revenue-generating mobile services."

The current version of the handset, the HNS-7100, is now available and is being exclusively deployed by mobile satellite operator Thuraya, with coverage in about 100 countries throughout Europe, the Middle East, north and central Africa, the CIS countries and south Asia -- a landmass inhabited by an estimated 2.3 billion people.

"Providing operators with the ability to successfully deploy value-added services is key to our growth in the broadband marketplace," commented Graham Avis, vice president of the HNS Mobile Satellite Terminal Products Group. "Java is central to this and Insignia provides the high performance and complete solution to meet our needs."

Last year, in Japan alone, over 10 million customers switched to Java-enabled phones to access a variety of premium services, from location-based travel assistance to interactive entertainment. The latest ARC Group market research study highlights that almost all mobile handsets will be Java-enabled within five years and estimates that nearly 1 billion handsets will be capable of running Java applications by 2006.
