2.3.1 Safety Guidelines
Before installing the Repeater, review the following safety information:
• Follow all local safety regulations when installing the Repeater.
• Only qualified personnel are authorized to install and maintain the Repeater.
• Follow Electro-Static Discharge (ESD) precautions.
2.3.2 Required BTS Information
Required BTS Information
• BTS channels
• BTS output power per channel
• BTS antenna gain
• BTS antenna height
• Distance from Repeater site to BTS
2.3.3 Criteria for Repeater Installation Location
The following criteria should be considered when selecting the Repeater installation site
location:
• Application type and general surroundings
• Available installation
• Install the Repeater in a shielded, ventilated, and easy-to-reach area.
• Verify that there is a minimum of a 50 cm (20”) radius of space around the
Repeater, enabling easy access to the repeater for maintenance and on-site
inspection.
• Distance from antenna site - It is recommended that the installation location be as
close as possible to the antenna site in order to maintain the cable loss to a
minimum.
• The Repeater is convection cooled so airflow and alternation should be possible.
• Follow Electro-Static Discharge (ESD) precautions.
• Install the Repeater close to the service area to monitor the output power.
• Use low loss cables to connect the antennas to the Repeater.
2.3.4 RF Cable Installation Guidelines
• For all coaxial connections to/from the Repeater - high performance, flexible, low
loss 50 ohm coaxial communications cable.
• All cables shall be weather-resistant type
.
• Cable length - determined by the Repeater installation plan. When calculating the
cable length, take into account excess cable slack so as not to limit the insertion
paths.
