Test the call quality of donor antenna
Fix the donor antenna after selecting the best position, and adjust slightly its height or angles in
order to get the signals with suitable input power level and calling Quality
System Requirement of GSM or DCS
1) The total input power level shall be around -50dBm, lowest shall be more than –80dBm
2) Test by mobile phone or data card by 3~5 times to make sure the calling quality is good
in 95% of the time, and no handovers.
3) It is requested that the leading BCCH shall be 6dBi higher than the second (for
professional engineering reference only).
System Requirement of CDMA or PCS
1) The total input power level shall be around -50dBm, lowest shall be more than –80dBm
2) Test by mobile phone or data card by 3~5 times to make sure Ec/Io is more than –7dB,
and no handovers.
3) Ec/Io of adjacent carrier shall be 8dB less than that of donor carrier to avoid soft
handover. The active PN shall be only 1.
8.5. Cable layout and connector assembly
1) Keep the type, specifications, routing direction, location, and curvature radius of cables in compliance with
the design requirement. Place cables in good order, bend them smoothly, and protect the outer skin against
any damage.
2) Bind cables in good order when laying them on cable racks. Keep cables within cable troughs, without any
cross, when you do not bind them. When leading cables in or out of troughs, use a hole-opener to open
cable troughs and then install PVC lock-nuts to protect them.
