ABSTRACT:
A medical telemetry system includes a central station having a central station receiver and a central station transmitter that both operate on a frequency bandwidth having frequency multiplexed transmission channels and guard bands. A guard band separates each of the frequency-multiplexed transmission channels. The central station receiver wirelessly receives patient data from one of the frequency-multiplexed transmission channels. The central station transmitter wirelessly transmits control data information via each of the guard bands. At least one patient monitor is provided that includes a patient monitor receiver and a patient monitor transmitter that both operate on the frequency bandwidth. The patient monitor is wirelessly connected to the central station. The patient monitor receiver is configured for wirelessly receiving the control data information from the central station transmitter via the guard bands. The patient monitor transmitter is configured for wirelessly transmitting the patient data to the central station receiver via one of the frequency multiplexed transmission channels.
