Discussions between commercial and government organizations about spectrum management are coming to a head as third-generation wireless devices that combine today's desktop terminal features and functions in a shirt-pocket-sized handset are poised to enter the marketplace. This communications evolution poses some critical issues for regulators as well as the military. Experts not only must confront the traditional spectrum allocation challenges, but they also must consider separation, partitioning, sharing and reallocation. The policy issue may reduce itself, on the one hand, to minimizing the costs of securing new spectrum for third-generation devices and, on the other hand, to the desire for greater global harmonization.

A new type of optical networking software will enable bandwidths of light to be redistributed in response to fluctuating data traffic. The technology allows individual streams of photons to be moved when and where they are needed, ensuring greater network reliability and near real-time communication.

As the United States and the European Union begin to implement policies designed to open their markets to foreign competition, issues such as wireless spectrum allocation, telephone interconnections and Internet access continue to vex negotiations. While both parties understand the importance of free trade and cooperation, these differences may impede bilateral trade liberalization and deregulation.

It is easy to understand why Gene Colabatistto might be tempted to get by on image. After all, ever since his company launched its first sensor-laden satellite in 1986, the international Spot system has captured and delivered millions of images of Earth-from the sands of the Sahara to the expanse of the Golden Gate Bridge.

Sensor fusion is taking place within the commercial remote sensing arena as military users combine different forms of satellite imagery to generate advanced intelligence and mission planning products. This imagery also is being combined with data from diverse sources such as unmanned aerial vehicles (UAVs) and topographical archives to redefine geospatial information.

For years, national technical assets were the only game in town for military users of remote sensing imagery. Now, however, a new generation of commercial imaging satellites promises to play an important role in future military operations. Their improved quality and increased versatility may even change tactics and strategy for theater activities.

Winning the Wars of the 21st Century" was the appropriate theme of West 2001, the first western conference and exposition by AFCEA International and the U.S. Naval Institute in the new millennium. The first of three days of panel discussions and distinguished speaker addresses generated lively debate over how to prepare for-and deter-war in an uncertain era.

A series of mobile groundstations soon will provide commanders with real-time detection and trajectory information about enemy theater and strategic missiles. Developed to operate with a new constellation of advanced early warning satellites, the air-transportable facilities will enhance the survivability of U.S. expeditionary forces.

Fast, agile units employing advanced sensors and situational awareness suites will soon become the U.S. Army's vanguard rapid deployment forces. Currently mustering and training at Fort Lewis, Washington, these interim brigade combat teams will rely on a variety of wireless communication and information technologies to detect, outmaneuver and engage more heavily armed opponents.

A consensus is growing among national security experts that the U.S. government's security policies must make space a top priority. If it does not, a space-based Pearl Harbor could be around the corner.
