Downlink gain setting
As for the downlink working performance, “orange” is a good working point. At this
time, downlink output power and coverage effect are stable.
But from another point of view, we hope the equipment is as far as possible away
from overloading status of “red” (thus the equipment would hold higher interference
depression ability). So we try our best to set the equipment near “edge point” when
engineering.
Setting of “edge point”: (Switch on the power supply after connection with donor
antenna and coverage antenna, and observe ALARM indicator.)
