As far as I know, the WifiManager class (who gives you all the information you can have on the WiFi state, see WifiInfo), doesn't provide this parameter.

Maybe you can magic something up with a rooted phone, but I don't thing you can do it on a standard

You can't with the standard Libarys as they don't allow access to the raw frames, however, this queston (about accessing raw frames in Java) says their is a wrapper for libpcap which may work (I haven't tryed it)

(see Sending frames in java)
