The Eartec Company offers ComSTAR, a new generation of full duplex wireless headsets for aircraft maintenance crews that need instantaneous, hands-free voice communications. The system enhances jobsite productivity and safety affording up to 16 users the ability to talk just like on a regular telephone within an 800-yard range. They feature miniaturized wireless circuitry and antennas built right inside the ear cup. It is totally portable and powered by rechargeable battery or AC power. The system is dual channel and includes a conference switch so that two separate groups can either talk privately or combine their signals. No FCC licensing or frequency coordination is required.
