For example, when using Gap (algorithms) frequency tables, one BSR can be
configured to hop frequencies by 2, while the other BSR can be configured to
hop frequencies by 6:

… …
In this way, at any given time, the two BSRs transmit on a different frequency
from the other (except for frequency 1 due to orthogonal method).
In summary, Airspan recommends increasing frequency allocations as much as
possible between BSRs with adjacent and overlapping sectors.
Note:
In all ASWipLL bands, the frequency spacing is 1 MHz. However, in
ASWipLL 3.
x
GHz the frequency spacing can be 1 MHz or 1.75 MHz (the
spacing, which is factory set, is determined by Airspan).
