    Abstract: A device may receive radio frequency (RF) transmissions from access points provided in a zone, and may calculate channel state information (CSI) for the access points based on the RF transmissions. The device may identify CSI phases that satisfy a phase threshold to eliminate surrounding movement in the zone and to focus on an entry location of the zone, and may perform a short-time Fourier transform of the CSI phases to generate a frequency versus time graph. The device may perform a spectrogram analysis of the frequency versus time graph or may process the frequency versus time graph, with a machine learning model, to determine a quantity of people in the zone and a start and stop times associated with entries and exits of the people to and from the zone. The device may perform actions based on the quantity of people and the start and stop times.

    Abstract: A method, apparatus, and system for providing improved EPGs are described. An availability, at a set-top box, of a media stream is determined, wherein the media stream includes one or more of a first plurality of programs associated with a subscriber. One or more electronic program guides indicating a second plurality of programs associated with the subscriber based on the availability of the media stream are accessed, wherein each of the second plurality of programs are accessible to the set-top box via a data stream that is separate from the media stream and the second plurality of programs includes at least one program of the first plurality of programs. Scheduling information associated with the one or more electronic program guides based on the availability of the media stream is retrieved via the data stream.
