 Installation
1 Project Survey
1) Received Single:
The donor antenna can receive signal of better than - 60dBm. If the signal not good then the REPEATER will not work, and easy to be self- exciting.
2) Isolation:
The vertical distance from donor antenna to service antenna should be at least 15 meters, or horizontal direction from donor antenna to service antenna should be at least 35 meters. Meanwhile the donor antenna and service antenna should be opposite, pointing at opposite direction.
3)  Height of service antenna.
It will mainly determine bound of coverage area. At least 20 meters height  of service antenna is recommend. It depends on embody condition of the coverage area.
4) Map drawing:
For more visual review, the overlook drawing and sectional drawing is necessary.(to see Figure1 and Figure2). The requirements of drawing are listed as follows:
 a) Contour Line is classified by 20m for the Map.
b) Shadow spot as the Coverage Area, the terrain of there whether is very plain with thin trees, single brick and civil engineering structures.
c) Sectional Drawing pls check as next of this overlook drawing in green line.
 
2  Project Implement
1) Installing of Donor antenna
    a) Tools for location         
    b) The requirement for received signal
    Received level for first BCCH:  more than -60dBm
    Received level for second BCCH:  less 10dB than first BCCH
     c) Holding up the Yagi antenna just to the space location, you should direct Yagi antenna to donor BTS.  Read and write out RX level value, Ec/Io value and PN number List for all PN.
     d) Check the data to see if the clause in "b)" above are met. if the clause  "b)" aren't met, adjust the space location and direction of the Yagi, untill the clause "b)" are met.
     e) You should install the donor antenna in accordance to the space location and direction of the Yagi.
     f) To connect the donor antenna to Fixed Terminal with RF cable, and make fine-tuning of the space location and direction of the donor, untill you get best value for received level and Ec/Io. Finally, you must be sure that "b)" clause are met.
 
2) Installing of Service antenna
Isolation: The vertical distance from donor antenna to service antenna should be at least 15 meters, or horizontal direction from donor antenna to service antenna should be at least 35 meters. Meanwhile the donor antenna and service antenna should be opposite, pointing at opposite direction.
Height of service antenna .It will mainly determine bound of coverage area. At least 20 meters height of  service antenna is recommend. It depends on embody condition of the coverage area.
3) Adjusting of REPEATER
First, you should adjust the UL and DL gain to the smallest, in other word, the attenuation should be the max 30dB. Second, you should increase DL gain 1dB by 1dB, untill you get the expected output power. If self-excitation happen, you need to adjust DL gain lower 5dB less than your current value.
Third, to set the UL gain lower 5-10dB than DL gain
4) Calling Test in coverage of REPEATER
