BBN Technologies

Low-Power Radio Development Award

Cambridge, Mass., April 25, 2005 — BBN Technologies, a leading advanced technology and research and development firm, today announced that it has been awarded $12.9M by the Department of Defense's Defense Advanced Research Projects Agency (DARPA). This funding is for the second and third phases of the Connectionless Networks program, which aims to drastically reduce the amount of energy required for mesh or ad hoc networking and communication.

In the second phase, BBN will develop working prototypes based on its technology concepts presented to DARPA in the first phase of the project. In phase one, BBN was able to reduce the energy used for delivering information in a tactical wireless multi-hop network by over 300 times. Working field units will be manufactured and deployed in the third phase, which begins in June 2006.

BBN's ability to reduce the amount of energy required for data networking will result in battery powered radios working hundreds of times longer. Furthermore, limiting energy requirements will potentially reduce the amount of money spent on purchasing and replacing batteries while increasing military effectiveness due to fewer concerns about how long batteries will last.

"When carrying a radio on a mission, two of the top concerns soldiers have are how much the radio battery weighs and how long will the battery last," said Jason Redi, division scientist at BBN Technologies. "Most networking systems are designed to transmit lots of data all the time, which makes them very inefficient and relatively power hungry when there isn't as much traffic to send. We are working on methods that are designed from the start to be efficient under all traffic loads, and adapt as things change on the battlefield."

The low-duty radio multi-hop networking schemes designed by BBN will one day lead to smaller batteries with increased battery life for use in battlefield communications devices. These devices range from data-collecting sensors placed in remote locations to radios used by soldiers to communicate with each other. More efficient networking and communications protocols will allow remote sensors to transmit important information over longer durations and allow soldiers to carry fewer batteries and replace them less frequently during missions.

This contract award comes on the heels of several new contract wins from DARPA. The projects for which BBN Technologies has been selected include: Force Multipliers for Urban Area Operations; Persistent, Robust 3-D All-Source Target Tracking Using Multistatic, Broadband Radar in Urban Combat Zones; and Social and Cultural Analysis and Learning Environment for Urban Pre- and Post-Conflict Operations
