GRC 802.11 Radio Deployment

Military Applications MR Assists with Rapid Deployment of Networks. MR enables mobile sub-networks to dynamically attach and reattach to multiple points on a network. MR “Set & Forget” Technology - Engineering/optimization is done prior to deployment.

Military Applications AWACS Home-Agent deployed in BGCC Communications link between BGCC and the Field Command Post Tactical data forwarded from surveillance satellites to the BGCC. Battle Group Command Center (BGCC) Foreign-Agent deployed in UAV Intelligence Control Center UAV Mobile-Router deployed in Armored Field Unit. Secondary communications link utilized due to lost LOS of primary. Non-preferred-path becomes preferred-path Preferred-path Non-preferred-path In case of communications loss of preferred-path Mobile-Router deployed in Armored Field Unit. Foreign-Agent deployed in Tracked Command Post Carrier. Unit deployed in vicinity of the battlefield.

Future Developments Multicast traffic to Mobile-Router. Routers behind Mobile-Router. Mobile-Router behind Mobile-Router. Secondary HA configuration. Mobile-Router’s registration over Asymmetrical Links.

Summary MR “Set & Forget” Technology - Engineering/optimization is done prior to deployment. MR assists with rapid deployment of networks. MR enables mobile sub-networks to dynamically attach and reattach to multiple points on a network. Performs well in long delay environments Redundancy can be engineered into a Mobile-Router network design.
