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 WCDMA or AWS
1) The total input power level shall be around -50dBm, lowest shall be more than –70dBm
2) Test by mobile phone or data card by 3~5 times to make sure Ec/Io is more than -6 dB
~–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.
3) Keep horizontal cables straight and fasten them stably with a fixing clip every 1 to 1.5 meters, with a proper
stress.
4) Bind and fasten vertical cables every two to three meters to avoid damaging cables or connectors owing to
their own heavy weight. Take back the cables and re-lay them when you have difficulty in pulling them, and
avoid using a strong force to pull them.
5) Separate RF cables from power cables. Take proper isolation measures if they have to be placed on the
Lightening
