Cambium Networks recommends using back- to- back (ABAB) frequency reuse, as shown in Example
layout of 16 Access Point sectors (ABCD), 90-degree sectors. This means that a base site of four sectors
can be created using two frequencies, which works very well and helps define networks in situations where
high capacity is required in a limited amount of spectrum.
The conditions necessary to implement this plan are:
