The Meraki MR36 has a coverage pattern where most of the signal goes sideways, and a bit up and down. This makes it perfect for mounting in offices on the roof where it spreads out sideways along the floor, but doesn't waste energy trying to punch through the floor or go up into the roof.
In a warehouse setting, the coverage might be different due to the high ceilings and the presence of racks. One user reported experiencing low or no coverage in some areas of their warehouse with 32 feet high ceilings and floor-to-ceiling high-density racking. The access points were mounted at ceiling height in the rows between racking.
In such cases, it might be more effective to use access points with directional antennas aimed down each aisle. This can provide better coverage at ground level, which is often where it's needed most in a warehouse setting.
As a rough guide, you might get good results with an access point covering a 30m diameter circle, or 706 m^2.
But, this can vary depending on the specific layout and conditions of your warehouse. It's always a good idea to conduct a site survey to determine the optimal placement and number of access points for your specific environment.
