3.2.1 REPEATER INSTALLATION CHECKLIST
Installation Location Requirement Considerations
Working Space available Ample space on mounting wall for instructed airflow
and cable routing. The recommended mounting space
is 300mmX300mmX300mm.
AC power supply at each installation location:
100~240VAC, 50/60Hz
Power cord length is 1.5m, use a dedicated AC
breaker or fuse circuit, and with good access to an
earthing point.
EMC and interference Do not locate near large transformers or motors that
may cause electromagnetic interference.
Maintain reasonable distance from chassis to
DT, MT antennas
Reduction of signal loss in feeder cable

3.2.2 ANTENNA INSTALLATION CONSIDERATION
Installation Location Requirement Considerations
Locate donor antenna in a site to receive the
maximum signals from the desired BTS and to
shield the other signals at the same time.
For maximum output power, Maximum input power =
Maximum Output Power – Gmax
Line of sight between BTS antenna and donor
antenna is required
Isolation of BTS antenna and mobile antenna
(I) must be larger than the maximum gain of
the repeater in operation.
I > Gmax+ 10dB
