does software like netstumbler and such have lower level diagnostic
There's a variety of apps for my phones that provide some info on WiFi
networks, but I think it's all sort of in the "received signal strength"
kind of level. I've not seen anything for timing. But that's not to
say that it doesn't exist.
I seem to recall some folks fooling with various timing parameters that
can be set into 802.11 chipsets from 10 years ago. Today's interfaces?
I don't know. The little interfaces that you put on a Arduino and such
expose a serial port kind of interface with a AT command set. I think
they bury most all of the stuff we'd want to know about.
