1. A glucose monitoring system, comprising:

  • a sensor configured to sample glucose levels of a user;

    a transmitter unit operatively coupled to the sensor, the transmitter unit comprising sensor electronics operatively coupled to the sensor to receive the sampled glucose levels and to transmit signals corresponding to the sampled glucose levels, a memory for storing a plurality of data points corresponding to the sampled glucose levels of the user, and a processor configured to generate one or more data packets for data transmission via the sensor electronics; and

    a receiver unit operatively coupled to the transmitter unit, the receiver unit configured to establish a wireless communication range with the sensor electronics of the transmitter unit and receive the one or more data packets from the sensor electronics of the transmitter unit when the receiver unit is placed within the established wireless communication range;

    wherein the sensor electronics include programming to transmit the one or more data packets with each data transmission, the one or more data packets including a current data point that corresponds to a glucose level of a current time period and at least one previous data point that corresponds to at least one glucose level of at least one previous time period, such that if the receiver unit does not successfully receive the current data point from the transmitter unit, at a subsequent data transmission, the current data point and the at least one previous data point are re-transmitted to the receiver unit with a new current data point, and the current data point is received at the receiver unit and ascertained from the subsequent data transmission.
