1Duration of action of moving object
If intermittent transmission is used to conserve battery life, then battery life is improved, but reliability deteriorates
Solution Approach 1:
The system implements periodic authentication exchanges between the sensor system and display device to maintain connection state without continuous data transmission. Authentication occurs at scheduled intervals to refresh security credentials while allowing data to be transmitted more frequently when needed, thus balancing battery conservation with reliable data delivery
Solution Approach 2:
The system performs authentication in advance before data transmission occurs. By establishing secure credentials and connection state beforehand, the system enables subsequent data transmissions to occur more efficiently without repeated authentication overhead, improving both battery life and transmission reliability
2Reliability
If continuous transmission is used to improve reliability, then reliability is improved, but battery life deteriorates
Solution Approach 1:
The system uses periodic authentication exchanges to maintain connection state without continuous data transmission. Authentication occurs at scheduled intervals to refresh security credentials while allowing data to be transmitted more frequently when needed, thus balancing battery conservation with reliable data delivery
Solution Approach 2:
The system maintains continuous connection state through periodic authentication while allowing intermittent data transmission. The useful action of data monitoring continues without interruption, but actual data transmission occurs only when necessary, preserving battery life while ensuring reliability
3Reliability
If authentication is performed for each transmission, then security is improved, but device complexity increases
Solution Approach 1:
The system performs authentication in advance before data transmission occurs. By establishing secure credentials and connection state beforehand, the system enables subsequent data transmissions to occur more efficiently without repeated authentication overhead, improving both battery life and transmission reliability
Solution Approach 2:
The system implements periodic authentication exchanges between the sensor system and display device to maintain connection state without continuous data transmission. Authentication occurs at scheduled intervals to refresh security credentials while allowing data to be transmitted more frequently when needed, thus balancing battery conservation with reliable data delivery

AI summary
Systems, devices, and methods are disclosed for wireless communication of analyte data. One such method includes, during a first interval, establishing a first connection between an analyte sensor system and a display device. During the first connection, the method includes exchanging information related to authentication between the analyte sensor system and the display device. The method includes making a determination regarding whether authentication was performed during the first interval. During a second interval, the method may include establishing a second connection between the analyte sensor system and the display device for transmission of an encrypted analyte value, and bypassing the exchanging of information related to authentication performed during the first connection. The method also includes, during the second interval, the analyte sensor system transmitting the encrypted analyte value to the display device, if the determination indicates that the authentication was performed during the first interval.
