3.7.2 Verify Link between BTS and Repeater
WARNING!
Perform this procedure before connecting the antennas to the Repeater or powering on the Repeater.
The Repeater should not be operated prior to the verification of the operating parameter in its
installation environment.
Before connecting the antennas or powering up the Repeater, verifying the Link between the
BTS and the Repeater
This test checks the signal strength from the BTS antenna to the Repeater.
Proceed as follows:
1. Using a Spectrum analyzer, measure the received signal from BTS at the Donor
antenna port near the Repeater.
2. Adjust the Donor antenna direction to receive the maximum signal strength.
3. Compare the received signal strength with the calculated signal strength from the
design phase.
In case of discrepancy, check for one of the following:
• Antenna out of direction
• Antenna tuned to side lobe instead of main lobe
• Antenna connector or antenna cable faulty
• Line-of-sight problem (obstruction), etc.
4. Register the signal strength of the downlink channel for the system operation phase.
