Patent number: 10673506Abstract: Approaches are described for accurate spatial diagnostics data and channel state information (CSI) recording due to dynamic bandwidth selection and other network changes in a wireless local area network (WLAN). Data transmissions such as channel soundings of a network, including data communications between networked computing devices on a communication channel of the network, can be obtained. The data communications can be associated with channel state parameters that can describe characteristics of the channel through which data is transmitted. The channel state parameters can be monitored overtime to detect a trigger event on the network. A type of trigger event can be determined based on channel state parameters before and after the event. Optimization parameters (e.g., operation parameters, calibration parameters, etc.) or other such information can be determined based on the type of trigger event.Type: GrantFiled: September 19, 2018Date of Patent: June 2, 2020Assignee: QUANTENNA COMMUNICATIONS, INC.Inventors: Debashis Dash, Hossein Dehghan, Georgy Gilyarovskiy
