US Patent 9071901 Wireless communication system for use by teams

A wireless communication system comprises a first wireless communication device for a first team member, and a second wireless communication device for a second team member. The first wireless communication device comprises a microphone and a transmitter for transmitting an oral message via a first wireless communication protocol. The second wireless communication device comprises a main transceiver, a headset, and a support for mounting the main transceiver to the second team member remotely from the headset. The main transceiver receives the oral message from the first wireless communication device via the first communication protocol and retransmits the oral message via a second wireless communication protocol to the headset for generating audio corresponding to the oral message. The second wireless communication protocol operates at a lower power than the first wireless communication protocol, and the first communication protocol operates over a longer range than second wireless communication protocol.
