The medical sensor system includes a gateway including a wideband receiver and a narrowband transmitter, each gateway receiving a wideband alignment frame using a wideband receiver from one or more wearable sensors. And arranged to transmit an acknowledgment frame using a narrowband transmitter that includes timing and control data for use by the sensor to establish timing for transmission of the alignment frame, and at least One wearable sensor includes a wideband transmitter and a narrowband receiver that transmits the sensor data to the gateway using the wideband transmitter and the acknowledgment from the gateway using the narrowband receiver. Receive frames, extract timing and control information from frames, and time And using the control information, it is arranged to adjust the synchronization timing and a wideband transmitter.
