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: 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 translation: 分配多个时隙，在该时隙期间为一个或多个目标无线设备执行定位过程。 将选择不同位置的多个无线接入点中的一个分配给每个时隙，使得分配给给定时隙的多个无线接入点被充分分离。 此外，无线接入点被分配给每个时隙的多个组中的相应一个组，使得分配给组乐曲的无线接入点被组中的无线接入点使用的信道发送一个或多个帧， 旨在引起来自一个或多个无线设备的一个或多个响应帧。
