Abstract:
A protocol controlled, four level radio communication system for use in a local area such as a hospital, that provides transceivers for fixed users such as patients, transceivers for mobile users such as health care providers, transceiver stations for each area within which a group of fixed and mobile transceivers operate, and a master command unit centrally located that ties together the transceiver stations and the fixed and mobile transceivers within the system. The patient transceivers permit the patient to select voice or signal transmission to specific or generic receivers. The health care provider transceivers permit the user to selectively receive, respond to, or acknowledge a transmission, or to initiate a transmission in a manner similar to the patient units. The stations have transceiver capabilities and may be staffed or may operate automatically to relay transmissions between transceivers or between other stations within the system. The stations have cellular switching systems that are connected to a number of broadcast antennas throughout the area within which a group of transceivers operate.
