Description

PRIORITY This application claims priority to and benefit of U.S. Provisional Patent Application No. 63/078,714, filed 15 September 2020, which is incorporated herein by reference. FIELD The subject matter described herein relates generally to systems, devices, and methods for in vivo monitoring of an analyte level. BACKGROUND The detection and/or monitoring of analyte levels, such as glucose, ketones, lactate, oxygen, hemoglobin AIC, or the like, can be vitally important to the health of an individual having diabetes. Patients suffering from diabetes mellitus can experience complications including loss of consciousness, cardiovascular disease, retinopathy, neuropathy, and nephropathy. Diabetics are generally required to monitor their glucose levels to ensure that they are being maintained within a clinically safe range, and can also use this information to determine if and/or when insulin is needed to reduce glucose levels in their bodies, or when additional glucose is needed to raise the level of glucose in their bodies. Growing clinical data demonstrates a strong correlation between the frequency of glucose monitoring and glycemic control. Despite such correlation, however, many individuals diagnosed with a diabetic condition do not monitor their glucose levels as frequently as they should due to a combination of factors including convenience, testing discretion, pain associated with glucose testing, and cost. To increase patient adherence to a plan of frequent glucose monitoring, in vivo analyte monitoring systems can be utilized, in which a sensor control device can be worn on the body of an individual who requires analyte monitoring. To increase comfort and convenience for the individual, the sensor control device can have a small form-factor, and can be assembled and applied by the individual with a sensor applicator. The application process includes inserting a sensor, such as a dermal sensor that senses a user's analyte level in a bodily fluid located in the dermal layer of the human body, using an applicator or insertion mechanism, such that the sensor comes into contact with a bodily fluid. The sensor control device can also be configured to transmit analyte data to a receiving device, from which the individual or her health care provider ("HCP") can review the data and make therapy decisions. The transmission of analyte data from the sensor to the receiving device can be performed using wired or wireless transmission. Prior art systems, however, have placed an increased emphasis on wireless transmission performed using near field communication (NFC) and/or Bluetooth communication. Wireless transmission improves the usability of the analyte monitoring sensor, allowing for manual or automatic transmission of analyte levels to the receiving device monitored by the user. To ensure transmission, a reliable wireless transmission signal should be maintained between the sensor control device and the receiving device. Thus, a need exists for a system, apparatus, and methods to ensure reliable wireless transmission of analyte levels from the sensor to the receiving device monitored by an individual or HCP.
