Signal Repeater Manual:
The Frequency Shift Repeater (FSR) is designed to solve problems of weak mobile signal, which can expand more coverage than RF repeater and reduce investment for the areas where fiber optic or dedicated cable is not allowed.
The system consists of two parts: Donor Unit and Remote Unit. The Donor Unit receives the BTS (Base Transceiver Station) signal via open air RF transmission or direct coupler closed to BTS, then converts it from the working frequency to the link frequency, and transmits the amplified signal to the Remote Unit that will reconvert the signal to the working frequency and provide the signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
Signal Repeater Features:
1.Out-of-Band FSR: the link frequency is out of the working band
2.Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding
3.Low interference to BTS by adopting linear amplifier with high gain and low noise
4.Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink
5.USB port provides a link to a notebook for local supervision or to the built-in wireless modem to communicate with the NMS (Network Management System) that can remotely supervise repeater’s working status and download operational parameters to the repeater

Signal Repeater Application Diagram:
To expand signal coverage or fill signal blind area where signal is weak or unavailable.
| Outdoor: | Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages, … |
| Indoor: | Hotels, exhibition centers, basements, shopping malls, offices, parking lots, … |
Q1. Why is there still no signal after installing the equipment?
1. Check the power on booster and power supply.
2. Check the connector of outdoor antenna is tight or not.
3. Check the connectors of RF cable are tight or not.
4. Check the outdoor signal is strong enough or not.
5. Check to make sure the antenna is installed correctly.
6. Check the connector of indoor antenna is tight or not.
7. Check the cable type is suitable or not.
Q2. Why the signal strength is too weak on the edge of area?
1. Check the outdoor signal and antenna direction.
2. Check booster is full gain or not.
3. Check all of the connectors are tight.
4. Change the location of outdoor/indoor antenna.
5. Check the cable type is suitable or not.
6. Deploy more indoor antennas.
Q3. After running booster, why the signals are not stable?
1. Checking the distance between donor antenna and server antenna are too close to each other? Check LED
of booster to make sure alarms are green.
2. Checking the signals from donor antenna whether to be stable or not?
3. Connect the system again if it is incorrect connection.
Q4. Why the booster power LED is not bright?
1. Checking the input AC power range indicated on power adapter whether is corresponding to the local
power system.
2. Checking the power adapter whether connect the equipment correctly and stably or not.
3. Checking the power adapter whether damage or not. To test output voltage whether be corresponding to
that indicated on power adapter or not by multimeter
