ANNAPOLIS, Md.--(BUSINESS WIRE)--March 14, 2002

Demonstrations Underscore how Location and Messaging can

Contribute to Increased Average Revenue Per User

TeleCommunication Systems, Inc. (TCS) (Nasdaq:TSYS), a key architect of wireless messaging and location software, today announced that it will demonstrate its ability to blend a broad range of location and multimedia messaging services in a way that increases wireless operator's average revenue per user (ARPU) at CTIA Wireless 2002.

The company will conduct demonstrations of an attraction finder application powered by TCS' Xypoint(R) Location Platform and Multimedia Messaging Service Center (MMSC).

The demonstration will illustrate how wireless operators can integrate various network capabilities to deliver content services that generate revenue. TCS will explain how its Voyager distributed architecture provides seamless integration of messaging and location using the Xypoint Location Platform and MMSC. Specifically, the demonstration will exhibit how the two components can be used together to deliver color graphics, such as a map, to provide directions to the nearest place of interest based on a subscriber's current location.

The Xypoint Location Platform is designed to support mobile operators as they evolve their messaging and location data services from existing systems to 3G networks. The platform's Location Center provides the intelligence that enables mobile operators to optimize their network and offer more complex and relevant applications. The Xypoint Location Platform is the first location solution to bring together the capabilities of location, presence and privacy.

The TCS MMSC manages the much-anticipated delivery of rich text e-mail, sound, fax, color photos, animation, video, Internet, and location services to multiple device types. As part of the Voyager distributed architecture, it is the first and only MMSC to fully integrate multimedia messaging and mobile location services.

TCS will also be demonstrating its wireless Instant Messaging application, MobiChat(TM). The demonstration will include PC, WAP, BREW and SMS client applications. Additionally, an SMS portal recently deployed with a large carrier customer will be featured.

Demonstrations of TCS' value-added wireless operator messaging capabilities, inter-carrier messaging functionality and wireless E9-1-1 capabilities will be highlighted. Various client applications using TCS' commercial messaging service, which include supply chain management messaging and wireless work order messaging, will be included.

Wireless operators interested in viewing TCS' messaging capabilities in action can view live demonstrations of messaging services, including enhanced message delivery, designed for various operators in the United States using TCS' Wireless Internet Gateway(TM).

The Wireless Internet Gateway provides support for enhanced messaging services (EMS), such as the ability to download ringtones, information alerts, reminder notes and graphics, as well as enhanced functionality for subscribers with Wireless Application Protocol (WAP) phones. In addition, the Wireless Internet Gateway can relay SMS messages across multiple air interfaces, providing further support for inter-carrier/multi-network messaging.

All demonstrations will be conducted March 18 -20, 2002, at TCS' Booth #4151, Hall C, held at the Orange County Convention Center, Orlando, Florida.
