Regulatory compliance for wide bandwidth WIFI-ranging measurements

A non-transitory computer-readable medium comprising computer-readable instructions, the computer-readable instructions when executed by a processor, cause the processor to:

• while performing non-Fine Timing Measurement (FTM) operations over a Dynamic Frequency Selection (DFS) Wireless Local Area Network (WLAN) channel of a first bandwidth, perform a DFS channel availability check (CAC) to determine whether a second bandwidth is clear of radar traffic, wherein the second bandwidth is wider than the first bandwidth;
• responsive to receiving a ranging request to initiate an FTM session and determining the second bandwidth is clear of radar traffic, modify the DFS WLAN channel from the first bandwidth to the second bandwidth to perform the FTM session;
• and
• upon completed performance of the FTM session, restore the DFS WLAN channel to the first bandwidth for performing non-FTM operations.

A method performable by an access point (AP), the method comprising:

• receiving a Wi-Fi ranging request comprising a ranging request to initiate a Fine Timing Measurement (FTM) session;
• responsive to receiving the Wi-Fi ranging request, determining whether a traffic load at the AP is higher than a threshold level;
• responsive to determining the traffic load is higher than the threshold level, rejecting the Wi-Fi ranging request;
• based on receiving a Wi-Fi ranging request and determining a second bandwidth is clear of priority traffic, modifying bandwidth of a Wireless Local Area Network (WLAN) channel on which the AP is operating from a first bandwidth to the second bandwidth to serve the Wi-Fi ranging request, wherein the second bandwidth is greater than the first bandwidth, wherein the WLAN channel is a Dynamic Frequency Selection (DFS) WLAN channel, and wherein determining the second bandwidth is clear of priority traffic comprises determining the second bandwidth is clear of radar traffic for a DFS regulation-specified time interval;
• and
• upon completed service of the Wi-Fi ranging request, restore the WLAN channel to the first bandwidth for performing non-ranging Wi-Fi operations.
