These are little "Are you there?" signals that ask nearby access points (routers) to respond, so the device knows which networks are available. Section 122 says: The Commission therefore only permits a client device to send a probe request to an access point after it has detected a transmission from the access point. The client device will be required to send the probe request on the same frequency as the access point's transmission. I think this translates to "passive scanning only", which is what NO_IR is meant to specify. NO-IR was previously called PASSIVE-SCAN, and was renamed when it was merged with NO-IBSS. Maybe the kernel's implementation needs work? I'm not a WiFi person so I really don't know all the details. > That is why drivers use the non 6Ghz for allowing clients to identify the router has 6ghz capabilities… I don’t think is for wireless-regdb to take over the HW router compliance and certification which is what 122. is about No, section 122 is definitely about client devices, which is what Linux devices are.

The Commission recognizes the utility of permitting probe requests to enable client devices to join an access point's network. However, these probe requests have the potential to cause harmful interference to licensed operations. The Commission therefore only permits a client device to send a probe request to an access point after it has detected a transmission from the access point. > > > > Best regards, > > > > Dennis > > > > > > On Wed, Feb 26, 2025 at 2:09 AM Ping-Ke Shih <pkshih@xxxxxxxxxxx> wrote: > > Chen-Yu Tsai <wens@xxxxxxxxxx> wrote: > > > > > based on this remove NO-IR flag and allow 30 dBm max power > > > > The original submission mentioned NO-IR requirements, though I did not > > find such wording.
