Methods and apparatuses for providing adverse condition notification with enhanced wireless communication range in analyte monitoring systems

An on body unit configured to be worn on a user's skin, the on body unit comprising:

• (1) sensor electronics, comprising:
• a first wireless communication circuitry;
• a second wireless communication circuitry, wherein the first wireless communication circuitry and the second wireless communication circuitry are each configured to operate autonomously;
• and
• one or more processors coupled with the first wireless communication circuitry, the second wireless communication circuitry, and a memory;
• and
• (2) a transcutaneous glucose sensor, comprising:
• a proximal portion electrically coupled with the sensor electronics;
• and
• a distal portion configured to be positioned under the user's skin and in fluid contact with interstitial fluid,
• wherein the memory of the sensor electronics stores instructions that, when executed by the one or more processors, cause the one or more processors to:
• receive, by the first wireless communication circuitry, an interrogation signal from a reader device,
• transition at least a portion of the sensor electronics, including the second wireless communication circuitry, from an inactive power state to an active power state in response to the interrogation signal,
• process time spaced signals received from the transcutaneous glucose sensor to determine if an adverse operating condition is present, wherein the adverse operating condition comprises a sensor failure condition, and
• in response to a determination that the adverse operating condition is present, cause the second wireless communication circuitry to transmit a notification signal indicating the adverse operating condition to the reader device.
