         7 . The device of  claim 6  wherein the control unit receives the data transfer request from the glucose meter. 
     
     
         8 . The device of  claim 6  wherein the control unit is in signal communication with the glucose meter based on radio frequency (RF) communication protocol. 
     
     
         9 . The device of  claim 1  wherein, in response to the data transfer request, the control unit transmits a current glucose data and one or more prior glucose data. 
     
     
         10 . The device of  claim 3  wherein the control unit transmits stored analyte data in response to the data transfer request. 
     
     
         11 . The device of  claim 1  wherein the control unit performs one or more of a prospective analysis or a retrospective analysis on the monitored analyte level. 
     
     
         12 . The device of  claim 1  wherein the analyte sensor requires no system calibration. 
     
     
         13 . The device of  claim 1  wherein the analyte sensor requires no user calibration. 
     
     
         14 . The device of  claim 1  wherein the analyte sensor is automatically calibrated. 
     
     
         15 . A method, comprising:
 receiving a plurality of signals from an analyte sensor related to a monitored analyte level;   processing using a processor the received plurality of signals to generate data corresponding to the monitored analyte level based on the received plurality of signals;   buffering the generated data corresponding to the monitored analyte level in a memory;   detecting a user initiated data transfer request; and   transmitting data corresponding to the monitored analyte level in response to the detected user initiated data transfer request.   
     
     
         16 . The method of  claim 15  wherein the data transmitted in response to the data transfer request includes glucose data. 
     
     
         17 . The method of  claim 15  wherein the data transmitted in response to the data transfer request is wirelessly transmitted. 
     
     
         18 . The method of  claim 15  wherein the user initiated data transfer request is detected using radio frequency (RF) communication protocol, or the data is transmitted using RF communication protocol, or the detection of the user initiated data transfer request and the transmission of data in response to the data transfer request is based on RF communication protocol. 
     
     
         19 . The method of  claim 15  wherein the buffered data is transmitted only based on the detected user initiated data transfer request. 
     
     
         20 . The method of  claim 15  wherein the transmitted data includes a current glucose data, a prior glucose data, or combinations thereof.
