XM Radio for Homeland Security Messaging?
XM Radio and Raytheon Co. have jointly built a communications system that would use XM’s satellites to relay information to soldiers and emergency responders during a crisis. The Mobile Enhanced Situational Awareness Network, known as MESA, would get a dedicated channel on XM’s satellites that would be accessible only on devices given to emergency personnel. The receivers would be the same as the portable ones available to consumers, with slight modifications to make them more rugged. Livescience.com has further details.
