    Abstract: A device may receive threshold data identifying threshold ranges, and may receive, from a first access point of multiple access points, first network data identifying first quality measurement indicators associated with a first link. The device may determine whether a first quality of the first link is good, fair, or poor based on comparing the first network data and the threshold data, and may provide, to the first access point and when the first quality is determined to be poor, a request for second network data identifying second quality measurement indicators associated with multiple links between the device and the multiple access points. The device may receive, from the first access point, the second network data, and may select one of the multiple access points based on the second network data. The device may utilize a link associated with the one of the multiple access points to receive video data.

    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.
