One-way devices do this is by sending out probe requests. These are = little "Are you there?" signals that ask nearby access points (routers) = to respond, so the device knows which networks are available. This is = why drivers use the non 6Ghz for allowing clients to identify the router = has 6ghz capabilities=E2=80=A6 I don=E2=80=99t think is for = wireless-regdb to take over the HW router compliance and certification = which is what 122. is about Thank you Best Regards, Rudy From: Dennis Bland =20 Sent: 05 March 2025 05:49 To: Ping-Ke Shih ; wens@kernel.org Cc: rmandrad@gmail.com; linux-wireless@vger.kernel.org; = wireless-regdb@lists.infradead.org Subject: Re: wireless-regdb: Allow 6ghz in the US Hi everyone: Section 122 of Document 2020-11236 (Unlicensed Use of the 6 GHz Band) = mentions the following, which formed the basis of the NO-IR requirement: 122. 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.

Dennis, do you have any ideas? >=20 FYI. The description below in [1] In all cases, an exception exists for transmitting brief messages to an access point when attempting to join its network after detecting a = signal that confirms that an access point is operating on a particular channel.
