2 Installation Guidelines
This provides guidelines for installing the HX 2.5 GHz TDD remote unit.
2.1 Site Considerations
• The distance between the HX service antenna and the coverage area should correspond to LOS (Line of Sight)
requirements for maximum coverage area.
• The maximum fiber path loss is 3 dB.
• The system delay of the optical system must be taken into consideration when there are neighboring BTS sites
overlapping in coverage.
2.2 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 with a relative humidity of max. 90% and
temperatures range of -20° to +60°C (-4° to 140°F).
2.3 Installation Requirements
• 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.
• Working space available for installation and maintenance for each mounting arrangement. Ensure unrestricted
airflow.
• Ensure grounding connector 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.
• 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 the equipment will be operated within the stated environment (refer to datasheet).
• Where appropriate, confirm available of suitably terminated grade of RF and optical fiber.
• Observe handling of all cables to prevent damage.
