TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a key architect of wireless messaging software, today announced it has recently been awarded three new certifications from Cisco Systems.

These specializations, which include Wireless LAN, Voice Access, and IP Telephony, demonstrate TCS's excellence in the next generation of complex networking technologies. TCS is one of only five companies in the nation certified in all three areas.

"Achieving these certifications is a testament to the expertise we've developed in seamlessly integrating solutions into Cisco's platform," commented Maurice B. Tose, president and CEO of TCS. "We are excited that we are able to align ourselves technically with Cisco as they continue their movement into the wireless arena."

TCS has completed a focused effort to increase the level of both Cisco sales and support capabilities within its organization. As part of the certification process, TCS met all the rigorous requirements necessary to achieve these specializations.

With these certifications, TCS has positioned its sales and service organizations to sell, design, install, and support Cisco Voice Access, Wireless LAN, and IP Telephony products throughout the world.

In obtaining the Wireless LAN Specialization, TCS adds to its already proven expertise in wireless communications, which includes its Wireless Internet Gateway and Short Message Service products.
