3.2.1 Required BTS Information
Required BTS Information
• BTS channels
• BTS output power per channel
• BTS antenna gain
• BTS antenna height and distance from antenna site
3.2.2 Installation Location Criteria and Environment
WARNING!! The signal booster must always be installed vertically with the connectors on
the underside for protection (see 3.4.4). Horizontal installation on a bench for long time may cause
damage to the signal booster due to over-heating.
The following criteria should be considered when selecting the Signal Booster installation site
location:
• Application type – indoor or outdoor
• Distance from antenna site and BTS antenna height.
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.
• General surroundings and accessibility of location
• In outdoor applications it is recommended to install a cabinet or a shielding sunroof for further
protection against weather wear.
• Use a suitable mounting surface, such as a flat back rigid wall.
• The Signal Booster is convection cooled so airflow and alternation should be possible.
• Install the Signal Booster in a shielded, ventilated, and easy-to-reach area – preferably at eye
level.
• Verify that there is a minimum of a 50 cm (20”) radius of space around the Signal Booster and 1
meter in depth (3 ft) in order to allow the unit door to swing completely open, enabling easy
access to the signal booster for maintenance and on-site inspection.
• Follow Electro-Static Discharge (ESD) precautions.
• Install the Signal Booster close to the service area to monitor the output power and noise figure.
• Verify that ambient temperature of the environment does not exceed 50°C (122°F)
