  • Patent number: 12389285
    Abstract: Systems and methods are provided for optimizing resource consumption by bringing intelligence to the key allocation process for fast roaming. Specifically, embodiments of the disclosed technology use machine learning to predict which AP a wireless client device will migrate to next. In some embodiments, machine learning may also be used to select a subset of top neighbors from a neighborhood list. Thus, instead of allocating keys for each of the APs on the neighborhood list, key allocation may be limited to the predicted next AP, and the subset of top neighbors. In some embodiments, a reinforcement learning model may be used to dynamically adjust the size of the subset in order to optimize resources while satisfying variable client demand.

  • Publication number: 20250212280
    Abstract: Systems and methods are provided for defining a split multi-link system. For example, the split multi-link system can define a multi-link device (MLD), where the MLD operates a first radio from a first AP of a plurality of APs and a second radio from a second AP of the plurality of APs through a Media Access Control (MAC) Service Access Point (SAP) of the split multi-link system. The first radio from the first AP and the second radio from the second AP may operate at different frequencies. The split multi-link system may also affiliate the first radio from the first AP and the second radio from the second AP with the MLD, where, using the MLD, the split multi-link system can transmit or receive one or more data frames from the MLD to a non-MLD or MLD client device using the first radio or the second radio.

  • Patent number: 12133073
    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.

  • Patent number: 12015561
    Abstract: Systems and techniques are described that are directed to intelligent scheduling of Wi-Fi services for applications, including enhanced dynamic prioritization. A device, such as an access point (AP), can receive data packets from multiple connected devices to dynamically identify an application flow for each data packet, and dynamically identify a user associated with the application flow for each data packet. The AP can generate prioritized candidate lists for selected data packets in queues corresponding to an access category (AC). In response to determining that the identified user associated with the application flow corresponds with a critical user, the AP can select data packets for the prioritized candidate lists based at least in part on priority policies for each of a plurality of applications and based at least in part on dynamic prioritization of applications for each of a plurality of applications; and schedule data packets from the prioritized candidate lists.

  • Publication number: 20240121846
    Abstract: Examples of performing selective Fine Timing Measurement (FTM) are described. For an FTM scan cycle, a first AP (i.e., an initiator) may determine scanning parameter values of a plurality of second APs (i.e., potential responders) based on previously performed FTM scans. The first AP may determine weights of the plurality of second APs based on the scanning parameter values and select a set of target APs based on the weights. The first AP may then scan the set of target APs for the FTM scan so that the rest of the plurality of second APs are relieved from participating in the FTM scan thereby reducing the performance impact on the rest of the plurality of second APs. After the FTM scan cycle is completed, the first AP may update the weights and select another set of target APs based on the updated weights to perform another FTM scan cycle.
