5.11 Recommended Channel Plans
The following sections will describe some pre-defined coloring schemes that will work in the
U-NII & ISM band with the AB-Access equipment.
5.11.1 Six-Sector, Three-Frequency Plan
This plan is good for Macrocells on relatively flat terrain:
• Use 1 channel guardband/separation between sectors (U-NII & ISM only)
• Use opposite polarization in opposite directions
• Use 4 meter back-to-back separation (or equivalent isolation)
• Use >1 meter separation between sectors
• Use same frequencies and sector allocations in each cell.
