Distances from the ROOT AP (RAP) to Mesh APs (MAPS) is 1000-4000 Ft with distances between MAP to MAP around 500-1000 Ft (this is because the MAPs are lower to the ground) and client distance from MAP for 2.4 GHz access is roughly 300-500 Ft (further if external antenna is used on the client).
The recommended distances for the Mesh backhaul is typically between 1000 to 4000 Ft as this assumes you are connecting a Root Mesh AP referred to as a "RAP" or Rooftop Access Point to a "MAP" Mesh Access Point (that's usually an AP mounted on say a telephone or street light pole using an Omni antenna).
hope it may help you .
