ISCO International Demonstrates Clarity Public Safety Solution at Industry-Leading APCO Conference

Business Wire, August 5, 2008

KANSAS CITY, Mo. -- In conjunction with a sweeping new initiative in public safety -- ISCO International, Inc. (AMEX:ISO), a leading wireless telecommunications solutions provider, announced today its invitation from the U.S. Department of Homeland Security (DHS) to participate in the acclaimed Association of Public-Safety Communications Officials (APCO) meeting here to demonstrate "Clarity Public Safety".

In addition to featuring its technology as part of a conference-wide briefing on the DHS Radio Over Wireless Broadband pilot program on August 7, ISCO will be showcasing its next generation solutions here during the week.

"ISCO's communications solutions deliver Active Situation Awareness that results in more rapid response from field agents by seamlessly integrating traditional land mobile radio, with broadband cellular networks and location based services," said Gordon Reichard, Jr., ISCO president and CEO. "We look forward to demonstrating our complete solution to the public safety audience at this important world-class conference."

ISCO International is a leading supplier of infrastructure and software solutions which increase the value of wireless networks. Clarity, a subsidiary, specializes in the design, development and deployment of software solutions that reduce costs while improving communications and operational efficiency for public safety users.

ISCO will be demonstrating:

* Next Generation PTT communications on packet data networks, including 3G Cellular and WiFi

* Cellular PTT interoperation with Land Mobile Radio

* Active Situational Awareness with near real time maps and GPS-enabled mobile devices

* Geographically defined PTT group calls

ISCO's Clarity Public Safety solution is actively being tested by the U.S. Department of Homeland Security. "The Office for Interoperability and Compatibility's ROW-B project is an important milestone in our efforts to advance interoperability progress," said Dr. David Boyd, Director of S&T's Command, Control and Interoperability Division. "The capacity to communicate among radio and broadband system users will significantly improve emergency response operations by allowing non-radio users to communicate with response units in the field."

By marketing Clarity Public Safety solutions, wireless service providers and reseller partners can offer value-add data services that increase their average revenue per user (ARPU) while offering a service that enhances public safety agency operations, including the deployment of personnel, interoperable communications between various groups and ongoing awareness of the geographic relationship between personnel and events.

Most of the 30,000 first responder agencies in the United States use 'land mobile radio' (LMR) networks. With the rapid advancement of 3G wireless technologies, Public Safety users are seeking to complement their existing LMR solutions with the advantages derived from 3G. Those solutions include more capable intelligent 3G handsets, interoperability between organizations, expanded network coverage and lower cost.

Renewed interest in public safety communications is reflected in the numbers. A recent study showed that government spending on IT applications for first responders is expected to grow to $21.3 billion by 2011. Public safety technological growth is also supported, at least partially, by Department of Homeland Security grants and other communications initiatives sponsored by the federal government.

ISCO sells it Clarity Public Safety solution through wireless service providers and system integrators, which include commercial cellular network operators, private cellular network operators, and MVNOs.
