  • Patent number: 11368847
    Abstract: A networking behavior detector and a networking behavior detection method thereof for an indoor space are provided. The networking behavior detector receives a plurality of radio frequency (RF) signals in the indoor space and converts the RF signals to a plurality of digital signals. Next, the networking behavior detector calculates an energy value of each digital signal and filters out the digital signal, the energy value of which is smaller than a threshold, of the digital signals to generate an analysis signal. Finally, the networking behavior detector retrieves a plurality of energy feature values of each analysis signal to generate a feature datum, and analyzes the feature data through an identification model to generate an identification result. The identification result corresponds to one of a plurality of networking behaviors.
