CAMBRIDGE, Mass., Nov. 5, 2012 /PRNewswire/ --The U.S. Army has selected the
Defense Advanced Research Projects Agency's (DARPA) Wireless Network after
Next (WNaN) radios to support the Network Integration Evaluation (NIE) 13.1
experiment at Fort Bliss. The WNaN team consists of DARPA; Raytheon BBN
Technologies, which provides the applications, networking and integration
capabilities for this next generation platform; and Cobham Sensor Systems LLC,
which provides innovative, low cost hardware. BBN Technologies is a wholly
owned subsidiary of Raytheon Company (NYSE: RTN).

The WNaN radio provides a robust mobile ad hoc network with dynamic spectrum
access, disruption tolerant networking, and multiple cooperative transceivers
on a compact, hand-held platform. These innovative networking technologies
allow WNaN radios to operate in dense signal environments without dropping
calls, facilitate mission command through the ability to easily set up as many
as 128 call groups, and maintain situational awareness even when
communications are interrupted. Because the WNaN software is delivered on low
cost, commercially available components, WNaN radios can enable soldiers at
every operational level to have a reliable communications device.

"Dynamic spectrum access" senses which spectrum is in use and automatically
shifts to the best available frequency. "Disruption tolerance" allows the
network to continue to advance message traffic toward its intended destination
even when there are outages or interruptions, and then delivers the message
when the necessary path becomes available. Traditional IP networks simply drop
the message packets whenever there is no complete path to the destination.
"Multiple transceivers" mean that the network can scale in density or size and
operate efficiently over multiple channels.

The WNaN system participated in NIE 12.1 as a System Under Evaluation
following a series of demonstrations where WNaN surpassed scalability
requirements by successfully transmitting voice and data traffic across 102
nodes in a tactical environment.

"We have tested the WNaN network extensively, and WNaN performance exceeds the
demands of today's Army," said Dr. Jason Redi, senior director of engineering
and WNaN principal investigator for Raytheon BBN Technologies. In coordination
with DARPA, the U.S. Army purchased 125 Version 4 (next generation) WNaN
radios in support of the NIE 13.1 experiment. The version 4 radio dramatically
reduces size, weight and power requirements compared with the earlier version
used at NIE 12.1, and it increases battery life to more than 10 hours.
