1. A medical sensor system comprising:

  • a gateway comprising a wideband receiver and a narrow band transmitter, the gateway configured to receive a wideband positioning frame using the wideband receiver from one or more wearable sensors and to transmit acknowledgement frames using the narrow band transmitter that include timing and control information for use by the one or more wearable sensors to establish timing for transmission of the positioning frame; and

    at least one of the one or more wearable sensors comprising a wideband transmitter and a narrow band receiver, the at least one wearable sensor configured to transmit a sensor data frame to the gateway using the wideband transmitter and to receive the acknowledgement frame from the gateway using the narrow band receiver, extract the timing and control information from the acknowledgment frame, and adjust timing and synchronization of the wideband transmitter using the timing and control information.
