2.4.2  Verifying the Link between the BTS and the Signal Booster 

This test checks the signal strength from the BTS antenna to the Signal Booster.  

Proceed as follows:  

1.  Using a Spectrum analyzer, measure the received signal from BTS at the Donor antenna port 

near the Signal Booster.  

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.
