Abstract: In response to receiving a probe request from a mobile client, an access point determines whether it should suppress a probe response. The access point receives a probe request from a wireless client device, and prepares a probe response to respond to the probe request. The access point determines whether the wireless client device is likely to associate with the wireless access point. Responsive to a determination that the wireless client device is unlikely to associate with the wireless access point, the access point suppresses the transmission of the probe response.

Abstract: Techniques are presented herein to coordinate ranging exchanges between base stations in order to enable any number of wireless devices in the vicinity of the base stations to obtain signals associated with ranging exchanges between base stations, time-of-departure report messages transmitted by the base stations to each other and time-of-arrival report messages transmitted by the base stations to each other, for use in computing the location of the wireless devices. Based on the multi-channel time-of-arrivals computed for the wireless device with respect to each base station, the multi-channel time-of-arrivals contained in the time-of-arrival report messages transmitted between base stations and the known locations of the base stations, a physical location is computed for the wireless device.

Abstract: A first device having a plurality of antennas wirelessly transmits multiple series of test packets to a second device having one or more antennas, each series of test packets being transmitted with a different level of interference imposed on the test packets. The first device determines a packet error rate for each series of test packets transmitted by the first device. The first device derives an estimate of an interference cancellation capability of the second device based on the packet error rate for different levels of interference.

Abstract: A wireless receiver (e.g., access point (AP)) is a member of a group of a plurality of receivers in a wireless local area network and time synchronized with other receivers in the group. A channel scan list is generated from a plurality of wireless channels available in one or more frequency bands. A channel is selected for the receiver to monitor from the channel scan list based on a current time at the receiver such that each of the plurality of receivers in the group are scanning the same channel at the same time. The selected channel is scanned and signal characteristic information (e.g., received signal strength (RSS)) is generated for the signals received during a given scan duration.

Abstract: Dynamic bandwidth selection techniques are provided for a plurality of wireless access point devices that operate in a wireless local area network. Each access point device is capable of serving wireless client devices with a bandwidth from a set of possible bandwidths associated with one or multiple contiguous or non-contiguous radio frequency channels. A bias is generated based on determined type of traffic or client composition for each access point device, the bias favoring a channel assignment that results in a particular bandwidth in the set of bandwidths. The bias is applied to metrics representing severity and degree of interference for each channel to generate adjusted metrics. A bandwidth from the set of possible bandwidths is selected for each access point device based on the adjusted metrics.
Abstract translation: 为在无线局域网中操作的多个无线接入点设备提供动态带宽选择技术。 每个接入点设备能够从与一个或多个连续或不连续射频信道相关联的一组可能带宽中为带宽提供无线客户端设备。 基于针对每个接入点设备的确定的业务类型或客户端组合产生偏差，偏好有利于导致该组带宽中的特定带宽的信道分配。 该偏差被应用于表示每个信道的严重性和干扰程度以产生经调整的度量的度量。 基于经调整的度量，为每个接入点设备选择来自该组可能带宽的带宽。

Abstract: Signaling preference order of links and maximum allowed links for multi-link operation may be provided. First, an Access Point (AP) Multilink Device (MLD) may receive an indication that a non-AP MLD supports preference ordering for requested links (that are indicated in the Per-STA profile sub-elements). Then the AP MLD may indicate that it supports preference ordering for requested links (that are indicated in the Per-STA profile sub-elements). Next, the AP MLD may receive from the non-AP MLD, a desired preference ordering for the requested link. The AP MLD may then consider the desired preference ordering for requested links.
