experienced users may find some benefit from adjusting the parameters, thus
optimizing the results for their specific needs.
4.2.6.2.18.2.1BU Height
Indicates the height (in meters) of the BU antenna. It is useful for calculating the
distance.
The available range is from 15 to 200 (meters).
The default is 30 (meters).
4.2.6.2.18.2.2BU/RB Antenna Gain
RB Antenna Gain: The antenna gain (in dBi) for a typical RB (BU only).

The available range is from 9 to 20 (dBi).
The default is 10 (dBi).
BU Antenna Gain: The antenna gain (in dBi) for the BU (RB only).

The available range is from 9 to 20 (dBi).
The default is 10 (dBi).
4.2.6.2.18.2.3BU/RB Maximum Modulation
RB Maximum Modulation: The maximum modulation of the RBs in the link.

The available range is from 1 to 8.
The default is 5.
BU Maximum Modulation: The maximum modulation of the BU in the link.

The available range is from 1 to 8.
The default is 8.
4.2.6.2.18.2.4KeepLink (BU only)
Use this option to instruct the BU to maintain sufficient fade margin after the
Noise Floor selection, in order to keep the current association. When this option is
enabled, the algorithm considers the uplink SNR of the RB currently in its
Association Database and calculates an upper limit for the Noise Floor. When this
