Publication number: 20230371127Abstract: Methods, systems, and apparatuses for managing a wireless network are described herein. A wireless network may include a gateway device, an access point, and a group of client devices. An analytics engine may determine a signal characteristic data for a client device, which may indicate network telemetry data for each of the client devices or associated locations during a time period. The analytics engine may utilize a trained classifier to determine that a signal characteristic indicated by the signal characteristic data for a client device satisfies a threshold.Type: ApplicationFiled: May 19, 2023Publication date: November 16, 2023Inventors: Tianwen Chen, Hongcheng Wang, Hong Li

Publication number: 20230292084Abstract: Systems, apparatuses, and methods are described for presence detection of a wireless device in a sensing region. Communication parameters determined by a computing device over one or more periods may be used to generate criteria for determining the occurrence of enter events or leave events. The criteria may comprise, for values of one or more communication parameters, rates of change associated with movement into or out of the sensing region. The criteria may be compared against subsequent data associated with the communication parameters to determine if an enter event or a leave event has occurred.Type: ApplicationFiled: May 23, 2023Publication date: September 14, 2023Inventors: Tianwen Chen, Hongcheng Wang, Hong Li

Publication number: 20220337440Abstract: At least one device can be classified based on user activity. At least one telemetry variable with respect to time may be received for the at least one device. The at least one telemetry variable with respect to time may be used to determine an activity model for the at least one device. Based on the activity model, a probability of the at least one device belonging to a profile or to a type of user may be determined. Based on the type of user of the at least one device, a setting associated with the at least one device may be changed.Type: ApplicationFiled: April 15, 2021Publication date: October 20, 2022Inventors: Tianwen Chen, Hongcheng Wang, Ding Zhou, Yonatan Vaizman
