1. An analyte monitoring system, comprising:

  • an analyte sensor for generating sensor signals, the analyte sensor configured to be positioned in fluid contact with a bodily fluid under a skin surface during a sensor lifetime, the sensor lifetime being a period of time between when the analyte sensor is initially positioned in fluid contact with the bodily fluid to when the analyte sensor is removed from continuous contact with the bodily fluid; and

    sensor electronics positioned on the skin surface and operatively coupled to the analyte sensor, the sensor electronics including;

    a voltage source to provide power to the analyte sensor to generate the sensor signals;

    a memory for storing a factory set calibration data associated with the analyte sensor, the factory set calibration data enabling the generated sensor signals to be processed without using a reference measurement during the sensor lifetime so as to generate calibrated analyte data;

    an application specific integrated circuit operatively coupled to the voltage source and the memory to process the sensor signals with the factory set calibration data without using a reference measurement during the sensor lifetime so as to generate calibrated analyte data corresponding to real time monitored analyte level during the sensor lifetime; and

    a data communication unit operatively coupled to the application specific integrated circuit and configured to wirelessly communicate the calibrated analyte data to a remote location using one or more spreading codes such that the one or more spreading codes have a transmission spectrum which is spread by a predetermined factor.
