3 Pre-Installation Requirements
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.
Ground the Repeater with the grounding bolt located on the underside of the Repeater.
Do not use the grounding bolt to connect external devices.
Follow Electro-Static Discharge (ESD) precautions.
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
3.3 Selecting a Location
Select a location that will take into account the following criteria:
Relative location of Base Station
Cooling and airflow
Wall compatibility
Access to the repeater for installation or maintenance
3.3.1 Relative Location of Base Station
The repeater site shall be located where the BTS signal strength is great enough to be
recognized by the system. For example, a CSR 3604-3304 (85dBm max gain) and signal
strength of -70dBm at the pickup antenna, a gain in the pickup antenna of 10dBi, a repeater
gain of 85dBm and a server antenna gain of 2dBi the resulting ERP would be 27dBm.
Losses in cables and other elements would change these figures slightly.
Repeater location near enough to BTS for received signal to be of adequate strength
BTS antenna. If the signal strength is high enough, LOS may in some cases not be
necessary.
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.
3.3.2 Cooling and Airflow
Install the Repeater in a shielded, ventilated, and easy-to-reach area.
The Repeater is convection cooled so airflow and alternation should be possible.
Verify that ambient temperature of the environment does not exceed 50C (122F)
Mount the repeater so that heat can be dispersed from it. The repeater wall mounting kit
ensures an optimum airflow between the wall and the repeater itself. Do not block this air
