If the “Alarm” indicator stays green when you change the donor antenna direction,
this means the donor signal is too weak and you will get degraded coverage even
no coverage. Following are what you need to do
5.2.3
Immediately report to the project manager and system design engineer.
5.2.4
Recommend to confirm the signal strength using a spectrum analyzer if
possible.
5.2.5
Work with your project manager and system engineer, check if you can
replace the donor antenna by a higher gain antenna to get better signal.
5.2.6
Work with your project manager and system engineer, check if you can
relocate the donor antenna to get better signal.
6. Connect the service antenna to REPEATER’s “MS” port.
7. Set all attenuation switches on the ATT switch panel to off position, unless the
system design document requires to reduce the uplink and down gains from
factory default values.
8. Check and ensure “BS” and “MS” ports are connected to feedlines.
Connect the power adapter and plug in the power supply.
Follow the test plan, walk test the call quality in the service area.
9. When it is needed, service antennas may be relocated to satisfy coverage
requirement. You will need to get approval from your project manager and
system design engineer.
10. During the walk test, if self oscillation (Refer to Section 3) is observed, this means
either the donor signal is too strong or antenna isolation is insufficient. Report to
the project manager and system design engineer. Repeat Step 4, 5 and 8 if
possible.
11. The gain of uplink or the downlink, or both needs to be reduced. Use the
combination of switches 1-5 for uplink and 6-10 for downlink to reduce the uplink
and downlink gain respectively. Repeat the walk test until the coverage is
acceptable. Document and report to project manager and system design
engineer on the gain value settlement.
Document the installation and test reports, and submit to project manager for approval.
