US Patent 11503433 System and method for managing sensors

There is described a system, method, and medium for managing a group of radio frequency (RF) sensors. The system comprising a first sensor, a second sensor and an upstream device. A sensor management system comprises a first sensor, a second sensor, and an upstream device. The first sensor is positioned at a first location and transmits a wireless signal. The second sensor is positioned at a second location and detects the wireless signal. The first and second locations of the first and second sensors correspond to an expected wireless signal of the first sensor. The upstream device performs an action in response to determining that a difference between the detected wireless signal and the expected wireless signal exceeds a predetermined threshold.
