  • Patent number: 5274666
    Abstract: A wireless communication system allow two-full two-way communication among a net or loop of stations. Each station is in direct communication with another member of the net such that a logical communication loop is created about the net. Each station combines its received signal with its own audio signal for retransmission to the next member of the loop whereby audio from said station is passed in turn to each of the other loop members. Transmission frequency hopping is utilized to insure system privacy and minimize interference with or from other loops operating in the same area. The system dynamically reconfigures itself to allow for the addition or dropping of a station without breakdown of the loop.
