Abstract: Embodiments of a device and method are disclosed. In an embodiment, a method for wireless channel scanning involves at a cloud server, building a set of channels for off-channel scanning to be performed by a selected group of wireless access points (APs), at the cloud server, determining whether the set of channels for off-channel scanning can be further pruned to generate a final optimized list of channels for off-channel scanning, and at the cloud server, sending the final optimized list of channels for off-channel scanning to the selected group of wireless APs.

Abstract: Embodiments of a device and method are disclosed. In an embodiment, a method for wireless channel scanning involves performing a wireless local area network (WLAN) scan and a spectral scan on a first channel of a channel scan list, and at the wireless device, performing the WLAN scan and the spectral scan on a second channel of the channel scan list after the WLAN scan and the spectral scan on the first channel are completed.

Abstract: The aspects include a method or system that identifies, by an access point (AP), an idle window in a fast locate scan interval. The AP can schedule a Block Acknowledgement Request (BAR) for an idle Station (STA) in the idle window. The AP may then transmit the BAR in the idle window to the idle STA. In response to the BAR, the AP can receive a Block Acknowledgement (BA). The AP may then determine a characteristic about the BA, and, based at least on the characteristic, determine a location of the idle STA.
