TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a world leader in highly reliable and secure mobile communication technology, today announced that it has been awarded additional incremental funding of $2.4 million to provide the U.S. Marine Corps (USMC) with field services support for its Wireless Point-To-Point Link-Delta Solutions (WPPL-D). The U.S. Army Project Manager for the Warfighter Information Network-Tactical (PM WIN-T) Commercial Satellite Terminal Program (CSTP) is managing these procurements through the Army's $5 billion World-Wide Satellite Systems (WWSS) contract vehicle.

The TCS WPPL-D system provides secure point-to-point and point-to-multipoint, line-of-sight and non-line-of-sight transmission of voice, video, and data communications. WPPL enables the USMC to close the gap on the "last digital mile," pushing data services to the network edge using a low-cost alternative to expensive beyond-line-of-sight satellite communications.

"The USMC understands the importance of providing dependable wireless deployable communications solutions to support its soldiers tasked with working in the most demanding conditions of current military operational theaters," said Michael Bristol, senior vice president and general manager of government solutions at TCS. "As our troops deal with extreme geographies while constantly on the move, they appreciate that the TCS WPPL-D system is easy to install and operate and provides reliable connectivity. This additional funding demonstrates the successful ongoing relationship between TCS and the USMC."
