Abstract: A method for accessing a wireless channel by a device (112, 113) that intends to transmit data, wherein access to channel is controlled by a wireless channel controller (111), the method comprising: registering the device (112, 113) at the wireless channel controller (111) as an authorized device; synchronizing (201) a timer of the device (112, 113) indicating time windows; determining (202) a designated time window during which the device (112, 113) can transmit data; performing (203) a clear channel assessment procedure during the preceding time window such that the clear channel assessment ends at the end of the time window preceding the designated time window; and beginning transmission (204) of data at the beginning of the designated time window.

Abstract: A method for identifying an interferer in a wireless network, the method comprising: providing at least two scanners configured to receive a wireless network signal and to determine the signal's angle of arrival; providing a controller configured to communicate with the scanners, wherein the controller comprises mapping data indicating the location of the scanners and a user interface; requesting at least one of the scanners to perform a scan of the wireless network channels to detect a highly utilized channel; requesting at least two of the scanners to detect the angle of arrival of the signal in the highly utilized channel to the particular scanner; determining a location of a source of the signal in the highly utilized channel based on the mapping data and at least two angles of arrival of the signal to particular scanners; and presenting the location of the source of the signal by user interface.

Abstract: A method for selecting a wireless channel for communication between a station and an access point (AP1) in a wireless ecosystem, the method comprising: prior to beginning regular transmission, scanning the wireless spectrum by the station to create a station-specific channel noise report that includes information on at least one channel and corresponding noise detected within that channel by the station; sending, by the station the station-specific channel noise report to (AP1); scanning the wireless spectrum by (AP1) to create an accesspoint-specific channel noise report that includes information on at least one channel and corresponding noise detected within that channel by (AP1); selecting by (API) the channel that provides the sufficient wireless link conditions for communication between (AP1) and the station, based on the station-specific channel noise report and the accesspoint-specific channel noise report; and starting regular transmission over the selected channel between (AP1) and the station.
