    Abstract: Techniques for generating a prediction for a location of a mobile device includes a network controller obtaining signal strength information and angle-of-arrival information for mobile devices from a plurality of access points disposed at a location that includes two or more zones. The network controller extracts features from the obtained information. The features indicate whether the mobile devices are more likely in a first zone than in one or more of second zones of the two or more zones. The network controller generates a software model for classifying a mobile device into one of the two or more zones by applying a computer learning process to the extracted features. The network controller uses the software model to generate a prediction indicating that a first mobile device is in one of the two or more zones, and performs an action at the location based on the prediction.

    Abstract: Various systems and methods for counting people. For example, one method involves receiving input data at an analytics system that includes a neural network. The input data includes a representation of an environment, including representations of several people. The method also includes identifying the representations of the people in the representation of the environment. The method also includes updating an output value that indicates the number of people identified as being present in the environment.

    Abstract: A methodology includes determining coarse location coordinates for a mobile device, anchoring the coarse location coordinates to a map, receiving inertial measurement unit data supplied by the mobile device, wherein the inertial measurement unit data is indicative of relative location coordinates of the mobile device, generating an unanchored path of the mobile device based on the relative location coordinates, and anchoring the unanchored path of the mobile device to the map in a position that optimizes a match between the coarse location coordinates and the relative location coordinates of the mobile device.

    Abstract: In one embodiment, a neighbor access point list is obtained. Statistics are maintained for a current access point that a client is currently associated with, including previous access points previous clients have roamed from prior to associating with the current access point, and next access points the previous clients associated with. The neighbor access point list for the client is optimized, by determining one or more previous clients that associated with a same previous access point as the client and prioritizing access points in the optimized neighbor access point list, based on the next access points the one or more previous clients associated with. The optimized neighbor access point list is sent to the client.

    Abstract: A methodology includes receiving from a first mobile device a first estimated location of the first mobile device and a first estimated error associated with the first estimated location, the first estimated location being based on first coarse data from a first wireless access point location determination system fused with inertial measurement unit (IMU) data from the first mobile device, receiving from a second mobile device a second estimated location of the second mobile device and a second estimated error associated with the second estimated location, the second estimated location being based on second coarse data from the first wireless access point location determination system fused with IMU data from the second mobile device, and based on the first estimated error and the second estimated error, determining a recommended change to a deployment of a wireless access point associated with the first wireless access point location determination system.

    Abstract: A method for adjusting an installation orientation of an access point within a predefined area with an associated orientation is disclosed. The method includes obtaining, at a computing apparatus, angle of arrival estimates from each access point based on a wireless transmission from a wireless mobile device. The computing device generates an estimated location of the wireless mobile device based on the angle of arrival estimates. Next, the computing device determines an orientation error for each wireless access point based on the angle of arrival estimate of the wireless mobile device and the estimated location of the wireless mobile device. The computing device generates an adjusted orientation of one or more of the access points based on the orientation error of the access point, thereby aligning the adjusted orientation with the orientation of the predefined area.
