    Abstract: Examples of techniques for handling fine time measurement ranging requests are described. In an example, an access point (AP) may receive a ranging request for initiating a Fine Timing Measurement (FTM) session. Responsive to determining that the client device is associated with the AP, it is determined that the ranging request is received after a threshold time from expiry of an FTM burst period of the client device. It is determined that the ranging request is within an FTM acceptance threshold of the AP. A number of consecutive unsuccessful FTM bursts between the AP and the client device is determined. In response to determining that the number of consecutive unsuccessful FTM bursts is less than an unsuccessful burst threshold of the AP, the FTM session may be initiated based on the ranging request.

    Abstract: Examples of techniques for handling multiple fine time measurement ranging requests are described. In an example, an access point (AP) may receive a ranging request for initiating an FTM session from each client device in a set of client devices. Based on the ranging request, a plurality of burst durations, each for performing the FTM session for each client device is determined. A maximum burst duration may be determined form the plurality. If a service time for serving high priority traffic is less than the maximum burst duration, a subset of the client devices is selected for performing the FTM session, where a sum of burst durations for performing the FTM session for each client device in the subset is less than the maximum burst duration. The FTM session for each client device in the subset is initiated.

    Abstract: A method for determining presence of a radar includes receiving a plurality of bursts in a dynamic frequency selection (DFS) channel of an access point, storing the plurality of bursts in a queue, in response to the queue comprising a threshold amount of bursts, determining a timespan of a first burst in the queue to a last burst in the queue, partitioning the timespan into at least a first group and a second group, determining a first number of bursts present in the first group and a second number of bursts present in the second group, in response to a difference between the first number of bursts and the second number of bursts equaling more than one, determining the radar is not present, and in response to the difference between the first number of bursts and the second number of bursts equaling one or less, determining radar is present.

    Abstract: Implementations of the present disclosure relate to resource allocation for clients of multiple co-hosted virtual access points (VAPs). A method comprises determining, by an access point (AP), a plurality of trigger frames for a plurality of clients connected to a plurality of VAPs of the AP based at least in part on respective workload levels of the plurality of clients. A trigger frame indicates a resource unit of one of the plurality of VAPs available for at least one corresponding client to access to the VAP. The method also comprises transmitting, by the AP, the plurality of trigger frames in parallel to the plurality of clients. By transmitting separate trigger frames for different clients in parallel, the efficiency of trigger frames can be improved and higher quality of service and lower collision will be provided.

    Abstract: Examples described herein relate to a method and a management system for evaluating an information technology (IT) infrastructure's vulnerability to a network attack. The management system determines whether a vulnerability evaluation template corresponding to a network attack is uploaded in a template repository. In response to determining that the vulnerability evaluation template is uploaded in the template repository, the management system transmits the vulnerability evaluation template to a sensor deployed in the IT infrastructure. The vulnerability evaluation template, when executed by the sensor, causes the sensor to generate an assessment indicative of a vulnerability of the IT infrastructure to the network attack. The management system receives the assessment from the sensor and reports it via a dashboard.

    Abstract: Implementations of the present disclosure relate to resource unit (RU) assignment to combat frequency selective fading. A method comprises determining, at an access point (AP), a plurality of channel qualities of a plurality of resource units (RUs) for a client. The plurality of RUs are configured to be available for communications with a plurality of clients comprising the client. The method further comprises determining, from the plurality of RUs, a target RU for the client based at least in part on the plurality of channel qualities. The target RU is to be used by the client for a following transmission with the AP. A target RU with good channel quality will be assigned to the client, thus the transmission and overall system performance will be enhanced.

    Abstract: Examples of techniques for handling fine time measurement ranging requests are described. In an example, an access point (AP) may receive a ranging request for initiating a Fine Timing Measurement (FTM) session. The AP may modify a channel width of a Wireless Local Area Network (WLAN) channel on which the AP is operating from a first channel width to a second channel width for performing the FTM session, where the second channel width is greater than the first channel width. In response to completion of an FTM burst associated with the FTM session, the AP may restore the channel width of the WLAN channel to the first channel width for performing non-FTM operations of the AP.
