Patent number: 10397065Abstract: A method for real-time monitoring and characterization of network conditions experienced by a client device coupled to a WLAN via at least one access point is presented. One or more primary performance parameters of the WLAN for a given operating interval of the client device uplink to the access point are received. At least one derived performance parameter based on the one or more primary performance parameters is computed. Trends of the primary performance parameter and the derived performance parameter are analyzed to identify occurrence of at least one problem signature. A situational awareness state characterizing the network conditions based on the at least one problem signature is defined.
