Interspiro’s groundbreaking communication system for firefighters

Developing the Spirocom wireless communication system

The project began when rescue services in Los Angeles wanted a voice-activated radio system with full duplex, meaning firefighters could speak to each other at the same time. They also wanted to keep their existing long-distance radio system for communication to the firefighter commander. Finally, they wanted an external loudspeaker so they could clearly speak to people in possible danger.
