Law enforcement agencies are benefiting from mesh network technologies developed originally for military use. Private industry is modifying versions of these types of communications systems to allow police and other public workers to share vital information more quickly and reliably than through cellular communications. The benefits are evident. While cellular communications rely on a central tower to relay messages that can become backlogged in emergency situations, mesh networks avoid this inherent problem by employing multiple routers set up around an area that allow messages to find alternative wireless paths to recipients.

After years of discussion, some military experts still disagree about the next step for the Operationally Responsive Space concept. While many believe the time for study and analysis is over, others say questions remain about the details of the capability's benefits for warfighting. Despite these differences, all agree that the time to move forward is now and that funding remains one of the biggest impediments to progress.

The latest version of a widely used commercial communications standard may soon provide U.S. troops with faster, more efficient networking technologies. Designed to greatly improve data throughput rates, the new rule also offers potentially greater operating ranges than current networks. However, the rule faces several challenges from developers before it can be fully approved.

An experimental technology soon may allow U.S. Air Force F-22 Raptor pilots to use the fighter's radar as a high-bandwidth communications system. This capability would enable F-22s and other platforms to transmit in near real time imagery and other files too large for rapid dissemination by current datalinks. The application could greatly enhance the U.S. Defense Department's network-centric warfare capabilities by turning tactical aircraft into reconnaissance and surveillance platforms.

A new network management technology soon may change the ways unattended ground sensors are designed and operated. By focusing on the radio systems that link individual devices, scientists hope to create an intelligent networking architecture that uses the radio's full communications capability both to conserve energy in a passive mode and to provide brief high-bandwidth data streams. Such operational flexibility would allow the development of multisensor devices able to activate a variety of onboard applications from microphones to real-time streaming video to meet intelligence collection needs.

Envision a future filled with millions of wireless nodes connected through a smart network that automatically adjusts to optimize communications performance. Achieving this reality would require developing low-cost devices and mitigating current weaknesses in networking technology. However, when this vision is realized, troops will be able to infiltrate areas devoid of communications infrastructure yet stay in touch with each other and platforms in the battlespace.

Back in 1946 when AFCEA and SIGNAL Magazine were new, the number-one technology problem vexing military planners was to provide mobile communications to the warfighter. Now, 60 years later, we face exactly the same challenge. Even though all of the other factors of warfare have changed, that problem still persists.

"Bringing home the bacon" is an old saying that in one of its interpretations means providing for the necessities of life. A new U.S. Air Force variation might be "bringing home the BACN"-or the Battlefield Airborne Communications Node, a force multiplier that will help offset force reductions and bring new, affordable communications capabilities of which the warfighter could only until recently dream.
