Abstract: A system includes a plurality of access point devices (APs) configured to provide a wireless network at a site, each of the plurality of APs having a known location, and a network management system comprising one or more processors and a memory comprising instructions that when executed by the one or more processors cause the one or more processors to: determine, based on a known location of a first AP of the plurality of APs, a known location of a second AP of the plurality of APs, and received signal strength measurements of wireless signals originating at one or more antennas of the first AP and received by one or more antennas of the second AP, an orientation angle of the second AP; and generate an output indicative of the orientation angle of the second AP.

Abstract: A network management system (NMS) is configured to control roaming in a wireless network using a variable mobility threshold. For a first wireless device associated with a current location, the NMS obtains at least one performance metric of a first wireless signal received by the first wireless device at the current location from a first AP of a plurality of APs, compares the at least one parameter of the first wireless signal to at least one performance metric of a second wireless signal received by at least one other wireless device at the current location from a second AP of the plurality of APs, and triggers a roaming operation of the first wireless device from the first AP to the second AP if the comparison satisfies a mobility threshold that varies based on the at least one performance metric of the first wireless signal.

Abstract: Techniques are described in which a network management system (NMS) is configured to determine a root cause of degraded network performance based on SLE metrics and the locations associated with network devices providing the SLE metrics. The NMS can determine service level experience (SLE) metrics associated with each client device on a network and location data for each client device of the plurality of client devices. The NMS can generate a time series of parameter vectors, where each parameter vector includes SLE metrics corresponding to each client device of the plurality of client devices. Each parameter vector is associated with the location of the client device corresponding to the SLE metrics. The NMS can determine, based on the time series of parameter vectors and associated locations, a root cause for a degradation in SLE metrics associated with the one or more of the client devices.

Abstract: Methods of deriving location information of a wireless device include deriving, in the continuous domain, a location of a wireless device and at least one time and location varying path loss function parameter. The coordinates and parameter are derived based on signal strength measurements made at the wireless device, with the measured signals originating from a plurality of wireless transmitters, such as access points. The derived path loss function parameter can include one or more of a path loss exponent parameter, an intercept parameter, a receiver antenna gain parameter, transmitter antenna gain parameter, or a transmit power parameter.

Abstract: A network management system (NMS) is described that determines a cause or contributor of an issue of an application session or predicts an issue with the application session and invokes one or more actions to remedy or prevent the issue. NMS is configured to determine one or more network features that cause and/or contribute to an issue of an application session that has already occurred (referred to herein as “reactive issue determination”) and/or predict an issue with an application session and one or more network features that impact the performance of the application session (referred to herein as “predictive issue determination”), and invoke one or more actions to remedy or prevent the issue, in accordance with one or more techniques of this disclosure.

Abstract: A network management system (NMS) automatically determines locations of deployed access points (APs) in a wireless network. The system identifies clusters of APs, wherein each AP in a cluster is a member of at least one robust quad, and wherein each robust quad in the cluster has three APs in common with another robust quad in the cluster. The NMS identifies one of the plurality of clusters as a gxlobal cluster and the remaining plurality of clusters as local clusters. The NMS determines coordinates of each node in the global cluster based on the coordinates of the anchor APs in the global coordinate system. For each local cluster, the NMS transforms the coordinates of each AP from the respective local coordinate system to the global coordinate system.
