Abstract
The vehicle crew communication system provides up to sixty wireless headsets that can be used with one base station, a range of 1600 feet from the base station for operation of the headsets, full duplex operation communication over digitally encrypted DECT protocol links from one base station to a plurality of headsets, pairing of each headset to a particular base station, use of wireless technology inside and outside of the vehicle, automatic channel and link selection to transparently avoid interfered-with channels and links, removal of the need to manually select a channel on the headset, and the combination of the noise-cancelling microphone with noise threshold, noise attenuation, and line echo cancellation tuned to intercom parameters. The invention may be used with or without a vehicle.
