TCS Demonstrates Fast, Precise Location Fixes Over Live 4G WiMax Network at CTIA WIRELESS 2008

ANNAPOLIS, MD, Mar 24 (MARKET WIRE) --
CTIA - Booth # 1341 - TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a
leading
provider of mission-critical wireless communications, today announced its live
demonstration of precise location fixes over a WiMAX network using the Secure
User
Plane for Location (SUPL) Assisted Global Positioning System (A-GPS) technology
in the
TCS Xypoint(R) Location Platform. Believed to be the first in the industry to
publicly showcase this capability, the TCS demonstration at CTIA WIRELESS
2008(R) runs
on a live, commercially-deployed WiMAX network in the Pacific Northwest.

Broadband Wireless and WiMAX market research and analysis leader Maravedis
Inc.
forecasts in its February 2008 report that WiMAX subscribers will exceed 100
million by 2014. However, the world of WiMAX is rapidly expanding beyond mere
broadband access. The TCS demonstration at CTIA uses the company's Xypoint
Location Platform to affirm that precise, location-based services on WiMAX end
devices are rapidly becoming a reality.

TCS' Xypoint Location Platform collects the GPS location using SUPL over the
WiMAX network. A Web-based location tracking application regularly queries the
Xypoint Location Platform for the laptop position and displays the resulting
location on a map. While TCS is using a SUPL-enabled laptop for the CTIA
exhibition, the technology is easily transferable to other wireless devices
such as WiMAX-enabled personal digital assistants.

"As a leader and innovator in the wireless industry, TCS is moving forward
with
the next generation of wireless communications and services," stated Drew Morin,
Senior Vice President and Chief Technology Officer. "By demonstrating the
technical feasibility of our 4G WiMAX location solution, we are making these
types
of services a reality and meeting end users' demands for enhanced LBS
solutions."

CTIA WIRELESS 2008, April 1-3, 2008 in Las Vegas, Nevada.
