Hi Team,
theoretically, having 3 radio transceivers, it is possible to
synchronize time with an accuracy of several dozen microseconds without
using TX timestamps.
One can take advantage of the fact that the reception of the same frame
by two different radio receivers is essentially simultaneous.
Differences caused by the different distances of the receivers from the
transmitter are negligible (nanoseconds).
I have a project working in an Ad-Hoc WiFi network and I need time
synchronization with an accuracy of several dozen microseconds.
All the drivers that I checked have only the software RX timestamps.
Is a synchronization protocol using only receive timestamps implemented
in PTP?
