5.11.2 Six-Sector, Six-Frequency Plan
This plan is good for Microcells or Macrocells on uneven terrain:
• Use 1 channel guardband/separation between sectors (U-NII & ISM only)
• Use opposite polarization in opposite directions
• Use 4 meter separation (or equivalent isolation)
• Use >1 meter separation between sectors
• Use a different set of three frequencies on alternating cells.

5.12 Antenna Spacing
In most Base Station deployments, multiple APs are placed on a single building or tower. To
minimize AP to AP interference, it is necessary to mount the antennas with proper spacing. Based on
the frequency plan identified, the following minimum spacing shown in the table below should be
maintained.
