Ok.. the story without out the whole media mambojambo and mixup
of things can be found at [1]. A description of the setup they used
can be found at [2] and [3]. What they basically do is to use two
fs frequency combs running at 200MHz, each on the transmitter and
receiver side and implement a two-way frequency and time transfer
using those pulses.
