4.3 Step by Step Installation Instruction

Fig.2 Installation Procedure

1. Find a proper indoor position where a good grounding path is available, usually

on a wall, and install the REPEATER following the steps given in the QUICK

START.

2. Follow the system design documents to locate the donor antenna ad service

antennas. The donor antenna and service antennas must have sufficient isolation,

and 90 dB minimum is recommended to ensure the device is working normally.

Donor antenna is typically installed on the rooftop or outside wall with high elevation,

avoiding any obstacle and in line of sight with the base station antenna. The

positions and number of service antennas must be designed properly by a qualified

Completion

Test for call qulitity

Adjust the direction of donor antenna

Connect power supply adapter

Measure receiving signal strength form base stantion

Install donor antenna and route feed lines

Install BDA on a wall

Indentify an installation location
