Abstract:
A remote telemeter for use in a medical telemetry system which supports real-time monitoring of ambulatory patients, comprising:a processor which receives and processes real-time physiologic data of a patient, the physiologic data measured by sensors which attach to the patient;a battery-powered transceiver responsive to the processor to transmit the physiologic data in data packets to selected receivers of a plurality of receivers, the plurality of receivers spatially distributed throughout a medical facility and coupled to a monitoring system such that different receivers provide data reception coverage for different areas of the medical facility, the transceiver switchable by the processor between a plurality of wireless channels that correspond to the plurality of receivers; anda control program executed by the processor to implement a wireless communications protocol in which the transceiver transmits the physiologic data to multiple different receivers of plurality on different, respective wireless channels and during different timeslots to provide redundant transmission paths, the redundant transmission paths providing spacial diversity, frequency diversity and time diversity.
