Abstract
A monitoring system includes a remote monitoring unit with a sensor unit in bidirectional wireless communication with a monitor unit. Information is transmitted bidirectionally between the sensor unit and the monitor unit. The monitor unit may inform the sensor unit that transmitted data has been corrupted, that the distance between the units is becoming too large, that transmission signal strength may be altered, that interference requires a change in transmitting frequency, or that attention is needed by the patient to the monitor unit.
