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.

Abstract
Method and system for providing data monitoring and management including RF communication link over which a transmitter and a receiver is configured to communicate, the transmitter configured to periodically transmit a data packet associated with a detected analyte level received from an analyte sensor, and the receiver configured to identify the transmitter as the correct transmitter for which it is configured to receive the data packets, and to continue to receive the data packets from the transmitter once the transmitter identification has been verified, is provided.

13. A continuous glucose monitoring and management system, comprising:
-
an RF communication link; a transmitter operatively coupled to the RF communication link, wherein the transmitter periodically transmits a data packet at each predetermined time interval; and a receiver operatively coupled to the RF communication link, wherein the receiver receives a first transmitted data packet during a data reception time window synchronized with a transmit time window of the transmitter based on a phase locked start indicator, the 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 first transmitted data packet does not include the transmitter identification information, 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 further, wherein the receiver receives one or more subsequent data packets from the transmitter when the transmitter identification information is verified based on the received first transmitted data packet; wherein the receiver processes the received first transmitted data packet and the one or more subsequent data packets when the transmitter identification information and the transmit time value of each data packet transmission is verified. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method of providing continuous glucose monitoring and management, comprising the steps of:
-
providing an RF communication link; periodically transmitting a data packet at each predetermined time interval 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, over the RF communication link, wherein the transmitter identification information is used as a seed number to determine transmission time for subsequent data packets that are randomly varied within a predetermined time window; receiving a first transmitted data packet over the RF communication link during a data reception time period synchronized with the selected transmit time window based on a phase locked start indicator, wherein the first transmitted data packet does not include the transmitter identification information; receiving one or more subsequent data packets over the RF communication link when the transmitter identification information is verified from the first transmitted data packet based on the received first transmitted data packet; and processing the received first transmitted data packet and the one or more subsequent data packets when the transmitter identification information and the transmit time value of each data packet transmission is verified. - View Dependent Claims (20, 21, 22, 23, 24)
