Setting the total uplink gain
The three uplink set points, highlighted in Figure 4-6, have to be balanced to a total
uplink gain appropriate to the ratio of the coverage areas for the BTS and the repeater.
Figure 4-6. Total uplink gain setting points
Coupling factors and power losses in the entire uplink chain, including the optic fiber,
have also to be considered when setting the total uplink gain.
A power calculator should be used when determining the uplink settings.
Some examples with various settings are found in Chapter 6, Commissioning.
