Not as far as I'm aware. I don't know much about Wifi mesh, but I'm guessing that it has two channels - one for being "master" and one for "slave".

I.e. the master channel is used to serve wifi to the nearby devices, and to the next wifi routers in a chain, whereas the slave channel is used to get wifi from any upstream routers.

We wouldn't describe that approach as FDMA - more that it has a separate channel for backhaul.
