TCS Commends the Signing of the New and Emerging Technologies 911 Improvement Act of 2008

(Marketwire Via Acquire Media NewsEdge) ANNAPOLIS, MD, July 23 / MARKET WIRE/ --

TeleCommunication Systems, Inc. (TCS)
(NASDAQ: TSYS), a leading provider of mission-critical wireless
communications, announced today that it commends the President and U.S.
Congress for the passage of the New and Emerging Technologies (NET) 911
Improvement Act of 2008, which was signed into law today.

The NET 911 Improvement Act of 2008 is intended to promote and enhance
public safety by facilitating the rapid deployment of IP-enabled 911 and
Enhanced 9-1-1 services, and encourage the nation's transition to a
national IP-enabled emergency network.

Since the NET 911 Improvement Act was introduced to the U.S. Congress in
August of last year, TCS has worked closely with the National Emergency
Number Association (NENA), the international Association of Public-Safety
Communication Officials (APCO), Voice over Internet Protocol (VoIP) Service
Providers and others in the public service community to encourage their
support of this legislation.

"We applaud President Bush and U.S. Congress for the passing of this Act,"
stated Tim Lorello, senior vice president and Chief Marketing Officer of
TCS. "This legislation clarifies the federal government's vision and
commitment to development and deployment of the next generation public
service and homeland security network. The new generation of VoIP and
cable IP-enabled operators will now have the same liability protection and
guaranteed access to the public safety infrastructure that normally has
been reserved only for wireline service providers. TCS is a demonstrated
technology leader in the development and integration of E9-1-1 network
capabilities, including location applications and services. We expect to
continue our long, successful relationship as a vendor of choice to the
public service community as the United States transitions to these advanced
services."

TCS has been enabling wireless E9-1-1 services for over a decade. Its
E9-1-1 system, which provides cable, VoIP, and wireless E9-1-1 service for
more than 140 million wireless and IP-enabled devices, is used to ensure
that consumers' emergency calls are routed to the appropriate Public Safety
Answering Point (PSAP) and automatically pinpoint and deliver a caller's
location information. TCS pioneered the methods by which PSAPs in the U.S.
are able to receive a wireless or Voice over Internet Protocol (VoIP)
subscriber's location during calls for emergency assistance. In addition,
TCS currently operates the only TL9000-certified Network Operations Center
in the world that supports emergency services for over 150,000 E9-1-1 calls

daily.
