1. A data monitoring and management system, comprising:

  • a communication link;

    a transmitter operatively coupled to the communication link, the transmitter configured to transmit a first data packet during a transmit time window selected from a plurality of transmission windows, the selected transmit time window determined based on transmitter identification information and a transmit time value, wherein the transmitter identification information is used as a seed number to determine a transmission time for subsequent data packets that are randomly varied within a predetermined time window; and

    a receiver operatively coupled to the communication link, wherein the receiver receives the transmitted first data packet during a data reception time period synchronized with the transmit time window based on a phase locked start indicator, wherein the transmitted first data packet does not include the transmitter identification information, and further wherein the receiver receives one or more further data packets from the transmitter when the transmitter identification information is verified based on the received first data packet;

    wherein the receiver processes the received first data packet and the one or more further data packets when the transmitter identification information and the transmit time value of each data packet transmission is verified.
