U.S. Marine Corps Funds $3.5 Million to Procure TeleCommunication Systems Wireless Point-to-Point Link System Components

ANNAPOLIS, MD -- (Marketwire) -- 04/28/09 -- TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a leading provider of mission-critical wireless communications, today announced that it has received a $3.5 million subcontract order for critical spare parts to support the U.S. Marine Corps' investment in Wireless Point-to-Point Link (WPPL) systems from TCS. WPPL systems provide deployed Marines with point-to-point and point-to-multipoint secure transmission of voice, video and data communications over terrestrial microwave radio links.

Under this award, TCS will provide back-up components and spare parts for the U.S. Marine Corps' current WPPL systems including radios, antennas, network gear, laptops and masts. The TCS WPPL provides Marines deployed in remote areas of the world with critical last-mile communications and allows them to extend their Local Area Network (LAN) to forward-deployed locations by extending services over terrestrial microwave radio links. The TCS WPPL allows for Non-Secure Internet Protocol Router (NIPR), Secret Internet Protocol Router (SIPR), Voice over IP (VoIP), Video, and Defense Switched Network transmission of vital information up to 30 miles point-to-point or 15 miles point-to-multipoint.

"While in the theater of Operations, our troops need to be prepared for just about any scenario and that includes having communications components readily available," said Michael Bristol, senior vice president of government solutions for TCS. "Since the number of WPPL systems fielded to date has grown tremendously, the need for critical items located in a centralized Depot Center will ensure Marines have easily accessible parts at their fingertips."

The TCS Government Solutions Group began as a systems integrator in 1987. Today, TCS provides engineering, management, and professional services to the public sector and is a leading provider of fixed and deployable communication solutions for government customers and mobile operators requiring high reliability and security, including the U.S. Army, U.S. Air Force, U.S. Navy, Unified Combatant Commands, U.S. Department of State, U.S. Department of Homeland Security, U.S. Secret Service, and various U.S. intelligence agencies.
