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: According to one or more embodiments, a first router receives a latency measurement indicative of latency associated with traffic sent from the first router to a second router. The first router calculates an asymmetrical latency as a difference between the latency measurement and a latency associated with traffic sent from the second router to the first router. The first router determines, based on the asymmetrical latency, a symmetrical latency target. The first router sends, to the second router, an indication of the symmetrical latency target. The first router and the second router adjust their respective de-jitter buffers to achieve the symmetrical latency target between the first router and the second router.

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: Techniques for access point (AP) based location computation are disclosed. A target wireless AP, communicatively coupled to a wireless station (STA), is identified. One or more location buddy APs, relating to the target AP, are identified based on the physical locations of the location buddy APs and the target AP. It is determined that a first location buddy AP, of the one or more location buddy APs, is communicatively coupled to the STA, and in response a location of the STA is determined using the target AP.

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: The method comprises, at a multiple endpoint power level orchestrator, assigning a first group identifier to a first endpoint device and assigning a second group identifier to a second endpoint device. The first endpoint device includes a first directional antenna and the second endpoint device includes a second directional antenna. Moreover, the first directional antenna provides a first coverage area and the second directional antenna provides a second coverage area. Additionally, the first and second coverage areas provide an overlapping coverage area. The method further includes obtaining a first collision report including the first group identifier from the first endpoint device and obtaining a second collision report including the second group identifier from the second endpoint device. The method further includes providing respective transmission power level adjustments to one or more of the first or second endpoint devices according to satisfaction of a performance metric.
