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.

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?"

Manufacturers are poised to release new equipment that will permit universal roaming for cellular telephone and mobile devices. Recent processor and software developments are leading to products that can operate across different global communications protocols.

Emergency responders now can count on priority cellular access in a pinch as the U.S. government establishes a wireless version of its Government Emergency Telecommunications Service. Known as the Wireless Priority System, or WPS, the new cellular system promises connectivity in a shirt pocket for authorized users ranging from the president down to a local fire chief.

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.

In the war against terrorism, ship and aircraft activity may be foremost on the nightly news and in the public eye, but in information-age conflicts an almost invisible force is just as critical to mission success. The military service members who build communications infrastructure from the ground up under combat conditions have become major contributors to winning battles fought by joint and coalition forces.

Miniaturized routers have been merged with mobile technology to give the military uninterrupted high bandwidth connectivity to mission-critical data as forces move throughout a theater of operation, all via one small rugged device. The capability could network troops in unique ways and solve defense-identified challenges of achieving seamless communications mobility between networks while addressing what is known as the form factor-maintaining a small device size and configuration. It can provide interoperability within a group as well as among defense organizations.

The U.S. military's goal of a network-centric warfare capability is a step closer to reality with the recent contract award for the development of a long-awaited family of advanced radios. The devices will eliminate communications difficulties between terrestrial and airborne units through the use of common waveforms, creating greater situational awareness and enhanced survivability for warfighters.

The Internet protocol revolution is reaching satellite video communications with a new system that permits transmitting tens of thousands of channels over a single orbital transponder. Users can leapfrog existing satellite video limitations with two-way virtual private networks that can carry streaming video without a hitch.

After considerable interagency debate, the U.S. government has approved ultrawideband radio technology for commercial use. Ultrawideband devices operate across a wide spectrum range instead of a specific frequency. This allows for more efficient spectrum use at lower power levels and presents a possible solution for bandwidth-starved wireless providers. Other applications include ground-penetrating radar, imaging, surveillance and medical systems. However, issues such as possible interference with navigation and commercial aviation systems must be resolved before the technology gains wider acceptance.
