3.2.1 INSTALLATION CHECKLIST
•
Working space available for installation and maintenance for each mounting arrangement. Ensure
unrestricted airflow.
•
Ensure earthing point is within reach of the ground wire.
•
Ensure a power source is within reach of the power cord. And the power source has sufficient capacity
(about 3.15A for AC).
•
Where appropriate, ensure unused RF connectors are terminated.
•
Do not locate the equipment near large transformers or motors that may cause electromagnetic
interference.
•
Reduce signal loss in feeder cable by minimizing the length and number of RF connections.
•
Ensure VSWR of antennas system < 1.5:1.
•
Ensure equipment will be operated within the stated environment (see datasheet)
•
Where needed, couple BTS RF signal with a coupler to prevent the equipment from damage.
•
Observe handling of all cables to prevent damage.
•
Donor antenna should have a narrow beamwidth and positioned in line of sight (LOS) to donor BTS site
so that the donor signal level is maximized. This allows the use of minimum gain to achieve the
maximum DL output power. The UL gain is typically set lower than or equal to the DL gain to minimize
noise interference to the donor BTS
•
Service antenna should be selected based on the type of service area, e.g., indoor antenna for indoor
application, and panel antenna for outdoor application.
