(the equipment would hold higher interference and depression ability at this stage).
So we shall try our best to set the equipment near “edge point” of green and intention
of tur ning orange during engineering.
?
Setting of “edge point”:
Switch on the power supply after connection with donor antenna and server antenna, and
observe ALARM LED.
?
If it shines “orange”, use 1dB as step to reduce the gain until “green” turns on, then increase
the gain 1~3dB attenuation value until “orange” starts to turn on, then brings back 1~2dB till
“green” is on, then fix the gain and the repeater ’s downlink output power reaches the perfect
status.
?
If it shines “green” then.
?
Please check coverage effect firstly, if the coverage effect is good, the engineering has
reached expecting target, thus there is no need to do anything.
?
To check whether the attenuation value has been set, if it is, use 1dB as step to increase
gain until the “orange” turns on, then brings back 1~2dB till “green” is on again , then the
repeater ’s downlink output power reaches the perfect status.
?
But if attenuation has not been set, it indicates that the input power is not strong enough to
let the repeater reach its good coverage.
If the coverage effect is not good, the donor antenna should be adjusted to get stronger
input signal. It is recommended that one person shall check the coverage effect inside
the building when the other person is trying to adjust the antenna or the repeater. At this
stage, please make sure “Orange” color will not be generated by self oscillation. Please
take off the server antenna to check if it is self oscillation or not: if the Orange turns to be
green, it is self oscillation; if it stays as Orange, it is not self oscillation. Please follow steps
in other page to turn Orange to be Green.

Uplink gain setting
Standard: uplink attenuation values =downlink attenuation values
Remark:
Avoid putting more than a 5dB difference between the Uplink and Downlink.
And Uplink gain must be equal to or less than DL gain, it can’t be more in order to
avoid interference with mobile network.
