Publication number: 20230080610Abstract: 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.Type: ApplicationFiled: July 11, 2022Publication date: March 16, 2023Inventors: Mohammad Zohoorian, Christopher Wesley Wright, Nagarjun Srinivasan, Jie C Jiang, Kevin Friday, Shmuel Shaffer

Patent number: 10944603Abstract: Modulated radio frequency (RF) packets are received from a wireless device, and converted to modulated baseband packets. Baseband parameters are derived from the modulated baseband packets. A baseband profile including the baseband parameters is created for the wireless device. A database including baseband profiles of wireless devices is accessed. The baseband profiles are classified under known device types based on baseband parameters included in the baseband profiles. The baseband parameters of the baseband profile are compared to corresponding baseband parameters of the baseband profiles in the database. If the comparing indicates a match between the baseband profile and one of the baseband profiles, the wireless device is classified under the known device type of the one of the baseband profiles, and the baseband profile is stored in the database under the known device type.Type: GrantFiled: May 17, 2018Date of Patent: March 9, 2021Assignee: Cisco Technology, Inc.Inventors: Matthew A.
