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 global 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.

Determining locations of deployed access points

Techniques are described by which a network management system (NMS) is configured to generate and monitor an RSSI-based proximity zone for a wireless network using a user interface (UI). The NMS may generate a UI comprising UI elements representing access point (AP) devices configured to provide a wireless network at a site; receive, at the user interface, an indication of a user input selecting one or more UI elements representing selected AP devices; establish a proximity zone for each of the selected AP devices based on an RSSI threshold value; receive network data comprising proximity information of a client device relative to the selected AP devices; generate, based on proximity assessments using the proximity information and the RSSI threshold value of the proximity zone, one or more proximity events indicating the client device relation to the proximity zone; and invoke, based on the proximity events, one or more actions.

Wireless access point proximity zones

Techniques are described by which a network management system (NMS) is configured determine a specific wireless channel assigned to a first AP device. The NMS is further configured to determine one or more neighboring AP devices that are within a certain proximity of the first AP device and generate a packetized scan command for each of the one or more neighboring AP devices. The NMS is further configured to send the packetized scan command to each of the one or more neighboring AP devices and receive, from the first AP device and each of the one or more neighboring AP devices, signal samples of a client device connected to the first AP device on the specific wireless channel assigned to the first AP device. The NMS is further configured to, based on the received signal samples, determine a location within the site of the client device.

WiFi location enhancement

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.
