As far as I've understood the TSFT is generated from the MAC, however I do not know to which instant the TSFT is relative, the first bit of the MAC payload, the beginning of the PLCP, etc. Also I do not know from which reference the TSFT is generated, I mean two AP synchronized using NTP will have consistent TSFT, which kind of error should I expect?
