2 Installation Guidelines
This chapter provides the general guidelines for installing the GX Quad-band Remote Unit and includes information such as
site considerations and installation requirements.
2.1 Site Considerations
 The distance between the GX service antenna and the coverage area should correspond to line of sight (LOS)
requirements for maximum coverage area.
 The maximum fiber path loss is 6 dB.
 The system delay of the optical system must be taken into consideration when there are neighboring BTS sites
overlapping in coverage.
 In the MIMO scenario, two remote units shall use a pair of optic fiber for each one. This ensures to avoid the system
delay difference between two units.
2.1.1 Installation Location
Mounting surface shall be capable of supporting the weight of the equipment.
In order to avoid electromagnetic interference, a proper mounting location must be selected to minimize interference from
electromagnetic sources such as large electrical equipment.
2.1.2 Environmental
Humidity has an adverse effect on the reliability of the equipment. It is recommended to install the equipment in locations
having stable temperature and unrestricted air-flow.
The installation location for the system should be well ventilated. The equipment has been designed to operate at the
temperature range and humidity level as stated in the product specifications at temperatures ranging from -40~70
o
C and a
relative humidity of maximum 95%.
2.1.3 Powering
The power supply unit provides power to all modules within the equipment. Depending on the product variant, it is
recommended that the PSU operates on a dedicated AC circuit breaker or fused circuit.
2.1.4 Grounding Requirement
Verify that the equipment has been well grounded. This includes GX Quad-band unit, external combiner, antennas and all
cables connected to the system. Ensure lightning protection for the antennas is properly grounded.
2.1.5 Cable Routing
Ensure all cables, e.g. power cable, feeder cable, optic fiber, commissioning cable, connecting are properly routed (use drip-
loops) and secured so that they are not damaged.
2.1.6 Manual Handling
During transportation and installation, take necessary handling precautions to avoid potential physical injury to the installation
personnel and the equipment.
