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.

Claims

1-20. -20. (canceled)

21. An apparatus, comprising:

sensor electronics configured to communicate a data packet during a transmit time window determined based on sensor electronics identification information, the sensor electronics identification information used to determine a transmission time for one or more additional data packets for communication, wherein the communicated data packet does not include the sensor electronics identification information, and further, wherein the communicated data packet is received at a remote location during a data reception time period that is synchronized with the transmit time window based on a start indicator.

22. The apparatus of claim 21, wherein the sensor electronics is configured to communicate the one or more additional data packets when the sensor electronics identification information is verified based on the communicated data packet.

23. The apparatus of claim 21, wherein the start indicator includes a phase locked start indicator.

24. The apparatus of claim 21, wherein the sensor electronics is configured vary the transmission time for subsequent data packets within a predetermined time window.

25. The apparatus of claim 24, wherein the determined transmission time for the subsequent data packets is varied within the predetermined time window based on the sensor electronics identification information.

26. The apparatus of claim 21, wherein the sensor electronics is configured to receive one or more signals from an analyte sensor in fluid contact with interstitial fluid.

27. The apparatus of claim 26, wherein one or more of the communicated data packet or the one or more additional data packets for communication includes data corresponding to a monitored analyte level based on the one or more signals from the analyte sensor.

28. The apparatus of claim 21, wherein the communicated data packet and the one or more additional data packets are processed at the remote location when the sensor electronics identification information is verified.

29. The apparatus of claim 21, wherein the communicated data packet received at the remote location during the data reception time period that is synchronized with the transmit time window is used to determine a medication administration protocol at the remote location.

30. The apparatus of claim 29, wherein the data packet is wirelessly communicated to the remote location.

31. A receiver, comprising:

a data communication section configured to receive a data packet during a data reception time window synchronized with a transmit time window of sensor electronics based on a start indicator, the transmit time window determined based on sensor electronics identification information and a transmit time value;

wherein the data packet does not include the sensor electronics identification information used to determine a data communication time for subsequent data packets that are varied within a predetermined time window; and

further

wherein the receiver receives one or more subsequent data packets from the sensor electronics when transmitter identification information is verified based on the received data packet.

32. The receiver of claim 31, wherein the data packet received from the sensor electronics includes measured glucose level.

33. The receiver of claim 31, further including a housing, the data communication section disclosed within the housing, the receiver further including a medication delivery component operatively coupled to the data communication section and disposed within the housing, the medication delivery component configured to determine one or more medication delivery protocol.

34. A method, comprising:

receiving a data packet during a transmit time window determined based on sensor electronics identification information, wherein the sensor electronics identification information is used to determine communication time for communication of subsequent data packets, wherein the data packet is received during a data reception time period synchronized with the transmit time window, and wherein the received data packet does not include the sensor electronics identification information; and

receiving one or more subsequent data packets when the sensor electronics identification information is verified from the received data packet.

35. The method of claim 34, further including processing the received data packet and the one or more subsequent data packets when transmitter identification information and the transmit time value of each data packet transmission is verified.

36. The method of claim 34, further including performing error detection on one or more of the received data packet or the one or more subsequent data packets.

37. The method of claim 36, further including performing error correction on the one or more of the received data packet or the one or more subsequent data packets when an error is detected.

38. The method of claim 37, wherein performing the error correction includes executing forward error correction.
