Hi Ben:

You need one STA and at least two APs (preferably on two different
channels) to make 802.11k/v test cases.  This is because Neighbor
Reports are not very useful with only one AP (the connected AP), and
802.11v Transition Management requires at least two APs for non-MBO
operation.

While hostapd and wpa_supplicant contain most of the protocol-level
functionality to send and parse the required elements in 802.11
management frames to support 802.11k/v, the logic implementation is
not complete.  For example, an AP central controller will send Beacon
Report requests to a STA through different APs, then analyze the
results to consider sending an 802.11v Transition Management request
to the STA.

Hello,

I started working on the beacon report request.  It appears that APs
cannot send to a station that is not connected to it.  So, in that case,
the controller cannod do what you suggest above.

Is this a limitation in hostapd or did I mis-understand what you are suggesting?

I *am* able to send beacon requests to a STA from the AP (hostapd) to which it
is connected.

Yes, you are correct - sorry for being unclear.  The AP can only send
beacon report requests to a currently connected STA.  In my original
comment, I was thinking of a scenario with multiple APs and one or
more STAs connected to each AP.  The AP controller would receive a
beacon report from each STA and determine if TPC or an 802.11v TM is
recommended for a particular STA.

It would be cool if you do request a beacon from any STA out there, but otherwise
it would seem you'd need to sniff on the AP(s) or something like that to know RSSI
of non-attached peers?

Actually, I just realized ANQP Neighbor Reports are defined in IEEE
802.11-2016, and are required for Wi-Fi Alliance WiFi Agile Multiband
certification.

This would be an STA sending ANQP to an AP though, right?

Either way, please post a patch if you code this up.

Thanks,
Ben
