Fire & Rescue
For firefighters who save lives and coordinate actions, clear communication is a must. When the flames are roaring and consuming all the oxygen in the air, sound waves have trouble traveling, and when building structures collapse and rumble, it is difficult to hear anything in regular headphones or to make oneself understood via a microphone. Holding a communication radio while also operating machines or fire hoses is also out of the question.
A firefighter responding to an incident needs to communicate with colleagues at the scene without interruption while also needing a secure channel to the external radio network to communicate with command. Moreover, the materials used in the communication equipment must be able to withstand extreme heat (read more in our technology section).
