Abstract: Systems and methods are provided for seamless roaming in a network. First, a client device is authenticated at a first access point of the network. Next, a processor selectively determines, among remaining access points in the network, second access points at which respective precursor keys, such as Pairwise Master Keys R1 (PMK-R1s) are to be computed. The second access points are determined based on any of respective path losses from the first access point to the second access points and respective historical frequencies at which the client device associates at the respective remaining access points. For the second access points, the respective PMK-R1s are computed and transmitted to the second access points to be cached. Next, following a request from the client device to reassociate to a second access point of the second access points, the client device is authenticated at the second access point based on a corresponding PMK-R1.

Abstract: Some examples of handling FTM requests comprises receiving a plurality of fine timing measurement (FTM) requests from a second network device over a first channel. Determining a channel traffic along the first channel. Adjusting a FTM response frequency based on the channel traffic. Responding based on the FTM response frequency, to a first number of FTM requests out of the plurality of FTM requests.

Abstract: Examples described herein provide coordinated ranging between APs in a network. Examples described herein may receive, by a computing device, neighbor adjacency information for a plurality of access points (APs) in a network, and based on the neighbor adjacency information, assign, by the computing device, subsets of the plurality of APs to non-overlapping zones. Examples described herein may initiate, by the computing device for each of the non-overlapping zones, ranging measurements between the subset of APs in the zone to generate a ranging result, wherein the ranging measurements between the subsets of APs in the non-overlapping zones are performed in parallel. Examples described herein may, based on the ranging results, resolve, by the computing device, locations of the plurality of APs.

Abstract: Currently, spatial reuse (SR) is a feature used indiscriminately for/across all traffic classes. However, systems and methods are provided for increasing the reliability of voice traffic and Transmission Control Protocol (TCP) Acknowledgement (ACK) messaging. The result is improved quality of voice calls, and enhanced network capacity. When the length of a data section of a packet suggests that subsequent packets are associated with voice traffic or TCP ACKs, such packets are not transmitted when another transmission(s) is occurring under spatial reuse. When a determination is made that the length of a data section of the packet suggests non-voice traffic or TCP ACKs, they can be transmitted simultaneously with other transmissions occurring under spatial reuse.

Abstract: Examples provided herein describe a method for managing power consumption of a network. For example, a network device may monitor a set of network area zones of a network coverage area, where each network area zone is associated with a set of edge devices. A first occupancy state may be determined for a first network area zone of the set of network area zones based on usage of a first set of edge devices of the first network area zone. Based on the determined first occupancy state, a first power consumption policy for the first network area zone may be determined. Responsive to determining the first power consumption policy, the determined first power consumption policy may be applied to the first set of edge devices in the first network area zone at least edge changing a power consumption mode of a first edge device in the first set of edge devices.
