To be honest I very much doubt the hardware in the wireless adaptors could measure time in single digit nanoseconds, and even if they could it would probably require a change in the over the air signal to use more bandwidth (spectrum) for a "pulse" to get better time resolution, which in turn would require hardware modification.
I would think the sound and signal strength meter are better metrics. Remember although signal strength is a bad indicator by itself, it can be much improved with 2 aerials and the large number of possible pairs to measure signal strength between in a well linked mesh.
