TCS Aids Philippine Disaster Relief Effort With Its SwiftLink(R) Deployable Communications Solution

Philippine Emergency Response Teams and Local Officials Gain Access to Voice and Data Communications Simultaneously

TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a leading provider of mission critical wireless communications, today announced the company supported the U.S. Marine Corps, III Marine Expeditionary Force, in its response to the Philippines' mudslide disaster relief effort with its SwiftLink® 2100 deployable communications systems. TCS' SwiftLinks were used for emergency response Voice-over-Internet Protocol (VoIP) and data communications. TCS provided its SwiftLink units for disaster response communications requirements until the Philippine government's communications infrastructure was operational once again.

To meet the critical needs for communications in the Philippines disaster area -- which lacked communications infrastructure following the recent mudslide catastrophe -- TCS configured its SwiftLink 2100 units for reach-back to the TCS gateway in the company's Tampa, FL, facility. Working in conjunction with the U.S. Marine Corps, III Marine Expeditionary Force, which provided local Philippine officials with TCS' SwiftLink portable command center, TCS configured the SwiftLink to deliver reliable communications for the officials leading the relief efforts.

TCS' SwiftLink 2100 portable field command center takes about 10 minutes to set up and uses satellite communications instead of the terrestrial infrastructure. It supports both classified and unclassified reach-back requirements of customers with fixed or mobile satellite communications using Inmarsat or Very Small Aperture Terminal (VSAT) systems.

"We are pleased to work with the U.S. Marine Corps to respond to the critical communication needs of local Philippine officials in this time of disaster," said Mike Bristol, Vice President, Network Solutions Group for TCS. "The SwiftLink solution is very reliable and well suited for disaster communications. They are ideally suited to the flexible, bandwidth-on-demand applications that emergency disaster response teams require and were similarly used for disaster recovery communications after the hurricanes in the United States in 2005."
