    Abstract: Determining a location of a user device comprises a wireless computing system supported by an access point. The wireless computing system receives a signal from the user device. The system estimates a location of the user device based on RSSI and calculates a boundary around the estimated location. The wireless computing system selects a plurality of sections inside of the boundary and performs a coarse calculation of a location of the user device based on an angle of arrival of the received signal. The system determines sections of the plurality of sections that have results from the coarse calculation that are more likely to be a location of the user device. The system performs a fine calculation of the location based on the angle of arrival of the received signal within each of the sections. The system identifies a particular section as the location of the user device.

    Abstract translation: 确定用户设备的位置包括由接入点支持的无线计算系统。 无线计算系统从用户设备接收信号。 系统基于RSSI估计用户设备的位置，并计算估计位置周围的边界。 无线计算系统选择边界内的多个部分，并根据接收到的信号的到达角度对用户装置的位置进行粗略的计算。 系统确定具有更可能是用户设备的位置的粗略计算结果的多个部分的部分。 该系统基于每个部分内的接收信号的到达角度对位置进行精细计算。 系统将特定部分标识为用户设备的位置。

    Abstract: A plurality of time slots are allocated during which a location procedure is performed for one or more target wireless devices. Select ones of a plurality of wireless access points at different positions are assigned to each time slot such that multiple wireless access points assigned to a given time slot are sufficiently separated. In addition, wireless access points are assigned to a corresponding one of a plurality of groups for each time slot such that wireless access points assigned to a group tune to a channel used by a wireless access point in the group that transmits one or more frames that are intended to provoke one or more response frames from the one or more wireless devices.

    Abstract: A wireless access point device configured to serve wireless client devices in a wireless network monitors transmissions sent by direct clients capable of forming ad hoc networks with one or more other direct clients. Profile data is stored for each detected direct client. The profile data indicates device type and services of the direct client, as well as potentially other information. The wireless access point receives from a direct client a request for information concerning one or more other direct clients, and sends a response to the direct client containing information for other direct clients based on the stored profile data.

    Abstract: In an example embodiment, a wireless device is configured to associate with a first access point on a first frequency. The wireless device listens for a predefined frame, which may be sent by neighboring access points or other wireless devices. When the wireless device receives a signal comprising a predefined frame, the wireless device acquires a parameter, such as signal strength, for the signal. The wireless device sends the parameter for the signal to the first access point.
