I'm pretty sure there isn't a quick way. You'd have to have a
wireless interface that supports 802.11 monitor mode, which not
all AirPort cards do, and you'd need to snoop for the probe
responses from the AP you're associated with (you'd need to
initiate the probes somehow), and you'd have to parse the raw
802.11 packets yourself. None of the functions for doing that in
the AirPort drivers are visible in the network interface API.
Yeah, I'm familiar with the external methods (passive mode grabbing
probe frames, etc.). For that I could use KisMac and Wireshark. I
just wasn't sure if there was anything even remotely close in the
API. I'm asking because a member of the University for which I work
was hoping to create an A-based network; forcing client cards to
use 802.11a and having some sort of tool to verify. I was going to
whip up something quick for him. Oh well.
I don't see why you want to force STAs to ignore the 2.4 GHz band.
It's a small slice of the spectrum with not a lot of channels, and it
doesn't take much time to scan it compared to the 5 GHz band. Just
don't deploy any access points in 2.4 GHz.
Not publicly available.
I don't want to pry, and if the question is not appropriate, it's
OK to disregard: Is the lack of these two functions due to security
concerns or Apple dev manpower?
I can't really speculate about why those interfaces aren't publicly
released. Apple Developer Relations might be able to help. It can't
hurt to ask them.
