Plastic Antennas Mold Flexible New Frontier
An electrically conductive resin technology may soon free warfighter and civilian wireless devices from bulky aerials. The proprietary recipe can be added to any of the thousands of polymers used to manufacture cases and components, turning the entire bezel of a cellular telephone or handheld radio into an antenna.
Extending the Software-Defined Radio Concept
The U.S. military is developing a modular, scalable, multifunctional radio frequency system that would provide unprecedented interoperability through its communications and data gateway while performing signals intelligence collection, electronic warfare and psychological operations broadcast. The technology incorporates common radio frequency hardware components networked with pools of processors that are programmed through software to instantiate a variety of radio frequency capabilities and perform multiple radio frequency functions simultaneously.
Data Rides on Beams of Light
A team of researchers from industry, academia and the U.S. Defense Department is creating high-speed, long-range communication technologies that will help eliminate the fog of war and take the element of surprise away from the enemy. The secure laser-based system will offer communication uplink speeds in the multigigabit-per-second range and will improve tracking so communications can be transmitted to satellites from mobile platforms. The research also will lead to aberration-free three-dimensional imaging at distances of more than 600 miles.
Researchers Jam More Data Through the Pipes
An experimental communications system may provide future combat vehicle crews with access to high-bandwidth intelligence and command and control applications. Part of a larger U.S. Defense Department effort to improve troops' ability to receive and send data, this research program is developing technologies to open communications channels down to the most spectrum-starved tactical user.
Weblogs Weave a New Communications Hub
The Office of Naval Research and the Naval Undersea Warfare Center are testing a commercial Web technology that will boost network centricity in the program management process. An enterprise weblog, a Web-based journal that supports information sharing, communication and collaboration all in one medium, is being employed during the test and evaluation phase of a night-vision technology project.
Communications Systems Meld for Greater Synergy
The desire to produce a truly joint radio for airborne, maritime and fixed station users has led two separate acquisition programs to merge. By combining their efforts, program managers hope to streamline the bidding and procurement process while creating more efficient equipment.
Spacecraft, Ground Equipment Triad Ensures Combat Connectivity
At the end of this decade, warfighters will begin using an advanced satellite system to maintain on-the-move connectivity with small handheld and vehicle-mounted radios. The planned constellation will provide U.S. military and civilian government agencies with a mobile communications capability that currently is not available. New waveforms and algorithms will permit cellular telephone-size devices to receive signals through dense jungle canopies and bad weather.
Large Data Pipes Link Vital Military Centers
The U.S. Defense Department is connecting key command, control and intelligence facilities around the world with a computer network capable of moving massive amounts of information. Designed to provide the bandwidth necessary to channel live video and sensor data from distant theaters back to commanders and analysts, the system will allow users to post and share documents in real time. This enhanced networking capability offers the military and intelligence communities a robust architecture for network-centric collaboration and decision making.
Computer Models Ensure Open Navy Communication Lines
Communication decision aids are enabling U.S. Navy shipboard-system developers to improve system designs and on-station communicators to prepare better communications plans by predicting performance. The tools help designers take into account the variables of the entire communications environment, including a sea of antennas or other obstacles that could block communications. Perhaps more importantly, the tool set helps commanders answer the quandary, "I have the systems, but can I communicate?"
Telecommunications Markets Look Past 2003
The telecommunications industry will see minimal growth this year in the wake of several large corporate bankruptcies and massive network overcapacity. Major issues such as mismanagement must be addressed to regain the trust of shareholders and government oversight agencies, analysts say. Sales of hardware will lag behind services as disillusionment settles in about the industry's performance. But a silver lining remains-the continuing growth of services such as broadband and wireless messaging.
