If you are referring to "wireless distribution system" then on a ZD you need to be looking at "meshing". APs wirelessly talking to APs to extend your infrastructure without physical cabling.
Caveat: once enabled on a ZD only a factory reset can remove it. Also lose 50% theoretical bandwidth. ZD supports 7363 & 7372 smart meshing. Others please correct me.
If you are thinking of some other WDS then bigger minds than mine will jump in.
