Abstract: A method includes estimating distances between a user device and an access point based on a series of FTM ranging bursts exchanged between the user device and the access point. The method also includes calculating a variance of the estimated distances and in response to determining that the variance exceeds a threshold, instructing the user device to perform an action that reduces the variance. Other embodiments include a device that performs this method.

Abstract: Providing for time sensitive networking (TSN) traffic in high density deployments is described. An access point (AP) is a high density deployment receives a message identifying another AP as a TSN neighbor and also detects a TSN device within an area covered by the APs. This arrangement may cause traffic interruptions for the TSN traffic between the TSN device and the APs. In order to prevent disruption in TSN traffic, a TSN time slot and a resource unit (RU) is determined for each of the APs, and the TSN traffic is communicated between the various devices in network according to the determined TSN time slot and RU.

Abstract: A method includes detecting, by a mobile device, a light sequence emitted from a light emitting diode associated with an access point and determining, by the mobile device, an identifier for the access point based on the light sequence. The method also includes reporting, by the mobile device, a geospatial location of the mobile device and the identifier for the access point to an automated frequency coordination (AFC) server to perform AFC for the access point.

Abstract: Techniques and apparatus for determining quality of experience (QoE) for wireless communications are described. One technique involves transmitting a QoE support message to an access point (AP) within an access network. The QoE support message queries whether the AP supports providing key performance indicators (KPI(s)) indicative of QoE provided by the access network. An indication of whether the AP supports providing the KPI(s) is received in response to the QoE support message. The KPI(s) are received when the AP supports providing the KPI(s). A determination is made whether to communicate with the AP based at least in part on the KPI(s). Communications are then performed in accordance with the determination.

Abstract: Hybrid ranging may be provided. A coverage environment may be divided into a plurality of areas and a corresponding plurality accuracy gradients for each of the plurality of areas may be determined. Passive ranging may be implemented for ones of the plurality of areas that have a high accuracy gradient and one of a high client device density and low client device movement. Active ranging may be implemented for ones of the plurality of areas that have a low client device density. Based on at least one of a level of client device density and movement speed of client devices, switching may be performed between passive ranging and active ranging for ones of the plurality of areas that have at least one of high client device density and high client device movement.

Abstract: Automating and extending path tracing through wireless links is provided by receiving a request to perform a network trace over a wireless link provided by an Access Point (AP) configured as a transparent forwarder between a trace source and a trace target; monitoring a trace packet from a first time of arrival at the AP, a first time of departure from the AP, a second time of arrival at the AP, and a second time of departure from the AP; monitoring a buffer status of the AP at the first time of arrival and the second time of arrival; and in response to identifying a network anomaly based on the trace packet and the buffer status, adjusting a network setting at the AP.

Abstract: A system and method for optimizing access points (APs) within a network comprises receiving, at a first AP, parameters corresponding to a second AP, and determining that the first AP and the second AP are part a first and a second wireless local area network (WLAN), respectively. The first and second WLANs support client credential sharing allowing seamlessly transitioning of a client device between the first and second WLANs using common credentials. Further, co-channel interference between the first AP and the second AP is detected based on the parameters corresponding to the second AP and parameters of the first AP, and at least one of a channel and transmission power of one or more of the first AP and the second AP is changed in response to the detection of the interference.

Abstract: Time Sensitive Networking (TSN) in wireless environments may be provided. First, a Radio Frequency (RF) profile associated with a station may be received by a computing device. Next, a number of Transmit Opportunities (TxOPs) to use for transmitting data between an Access Point (AP) and the station based on the received RF profile may be determined. The determined number of TxOPs may then be provided to a wireless controller associated with the AP.

Abstract: Techniques for wireless optimizations are provided. A first set of values for a set of network benchmarks is received from a sensor device, where the set of network benchmarks define network performance dimensions, and include a number of retries needed to successfully transmit data. A second set of values for the set of network benchmarks is received from a wireless access point. The first set of values is mapped against the second set of values in an n-dimensional space, and an outlier dimension is identified, based on analyzing the mapped first and second sets of values. The wireless access point is then reconfigured, based on the identified outlier dimension.

Abstract: In Wi-Fi 8, backscatter devices (BKDs) may be viewed as part of the 802.11 wireless local area network (WLAN). BKDs in a WLAN have limited transmission interactions with a Wi-Fi access point (AP). Onboarding BKDs to the WLAN is described, which allows for the AP and BKD to participate as elements of the same local network, with security controls. The onboarding of the BKD to a WLAN may occur after discovery of the BKD at an AP and includes replacing an Initial Device Identifier (IDevID) on the BKD with a Local Device Identifier (LDevID) in order to provide for secure communications between the BKD and the WLAN.
