April 2002
By Maryann Lawlor

Although industry shoulders the ultimate responsibility for the health and well-being of the U.S. telecommunications infrastructure, the federal government is working to ensure the continued operation of systems that touch almost every aspect of life-from emergency services to economic stability.

Chinese Naval Sonar Evolves From Foreign Influences

December 2002
By James C. Bussert

The types of sonars equipping Chinese warships are a barometer of Chinese naval technology and antisubmarine capability. The evolution of Chinese sonar from old Soviet equipment to series production, to indigenous designs, to French examples and finally to modern Russian vessels with sonar suites parallels Chinese naval progress. Just as these systems have grown from secondhand gear to indigenous designs supplemented by up-to-date foreign technologies, so has the Chinese navy transitioned to a force designed to serve the nation's maritime needs.

By Robert K. Ackerman

More than 10 years of hardware, software and signal processing upgrades have transformed the Patriot missile system into an effective defensive shield against short-range and theater tactical missiles.

Off the Shelf, Into Battle

August 2004
By Vice Adm. Herbert A. Browne, USN (Ret.)

A few weeks ago, there was a story on the evening news about a waitress in Texas whose son is a Marine stationed in Iraq. Although his unit could communicate with the higher echelons, its members were having difficulty communicating with each other while on the battlefield. He asked his mom to go to a local electronics store, buy a set of walkie-talkies and send them to him. She was happy to help the war effort, but what she didn't anticipate was the hit the equipment would be with her son's buddies who wanted walkie-talkies of their own.

Digitization Brings Quantum Growth in Geospatial Products

August 2004
By Robert K. Ackerman

The National Geospatial-Intelligence Agency, fresh from assuming a new name less than a year ago, is striving to meet several self-imposed goals to address shortcomings and to confront the challenges of 21st century network-centric warfare. On its to-do list are converting fully to digital products and services; pursuing an e-business model; and transforming its architecture. It also seeks to pursue advanced forms of geospatial intelligence, including electromagnetic spectrum, and to mature the ability to capitalize on airborne collection. And, the agency's leadership foresees a need for two new headquarters facilities to deal with burgeoning responsibilities and an increased terror threat.

Wireless Security Takes Shape at Defense

August 2004
By Robert K. Ackerman

The future of the network may be wireless, but without security there can be no wireless network access for the military, according to the U.S. Defense Department. The department has issued a set of guidelines establishing policy for the use of commercial wireless technologies in the Global Information Grid, or GIG. The goal is to exploit the advantages of emerging wireless technologies without compromising the very core of the military's network-centric doctrine.
