TCS Wins $3.3 Million U.S. Marine Corps Contract for Wireless Point-to-Point Link Network Systems and Support

Contract Awarded to Provide Cost-Effective, Reliable Last-Mile Communications to Deployed Remote Locations

ANNAPOLIS, MD–(EMWNews – August 20, 2008) – TeleCommunication Systems, Inc. (TCS)

(NASDAQ: TSYS), a leading provider of mission-critical wireless

communications, today announced that it has received a $3.3 million

contract to support the U.S. Marine Corps for its Wireless Point-to-Point

Link (WPPL) Network solution including ongoing maintenance and support.

The order requires TCS to deliver systems for use by the U.S. Marine Corps

in support of Operation Enduring Freedom (OEF) and Operation Iraqi Freedom

(OIF) over the next sixty to ninety days.

During the next several weeks, TCS anticipates securing additional WPPL

orders with a total value exceeding $40 million against its 2007 World-Wide

Satellite Systems contract with the U.S. Marine Corps with a potential

total value of $70 million including all option years, through 2011.

“Reliable and uninterrupted communications in the field are critical for

deployed troops especially in places like Iraq,” stated Michael Bristol,

Senior Vice President, TCS Government Solutions Group. “With our proven

track record of successfully providing the Department of Defense with

wireless technology to support the transmission of multiple types of data,

TCS is the go-to resource to meet the communications needs of our armed

forces. It is an honor to provide this technology to our brave men and

women protecting freedom around the world.”

the world with point-to-point and point-to-multipoint, line-of-sight and

non-line-of-sight transmission of voice, video and data communications.

Non-Classified Internet Protocol Router (NIPR), Secret Internet Protocol

Router (SIPR), Voice over IP (VoIP), Video, and Defense Switched Network

transmission of vital information up to 35 miles point-to-point or 15 miles

point-to-multipoint.
