Prescott, AZ – Technology previously used by the military could give fire crews an edge as they battle wildfires. Persistent Systems LLC has a technology called The Wave Relay system, which uses Android devices, enables two-way, real-time voice and video communications, even in remote areas. As CNET’s Sumi Das reports, for CBS The Early Show, the Prescott, Ariz., fire department, which lost 19 Hot Shot firefighters last year, is testing the technology.
