RE: wireless-regdb: Allow 6ghz in the US

[<rmandrad@gmail.com>]

Hi Dennis, et all

122. is not specifying NO-IR which basically is denying any 6Ghz in the US what it means in my opinion is 

Client devices (like phones, tablets, laptops) need to find Wi-Fi networks before they can join them.
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… I don’t 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

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.

Best regards,

Dennis

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.
