2,Product Display

The LCD Repeater covers all existing wireless public communications networks:

DCS/LTE 1800MHz, WCDMA 2100MHz,LTE2600Mhz

WCDMA2100 LTE2600 25dB Real Time Line Repeater LTE1800 2


The LCD Repeaters have many intelligent functions: such as antenna isolation detection, Input & Output signal strength indication, system indication, manual gain control and smart mode. See the detailed introduction listed below:



The Display will auto off if don't touch it in one minute.


1. “GREETWIN” is Company LOGO.

2. Power: Power supply with indicator.

3. Smart: Smart function with indicator. AUTO Mode now.

4. M: “AUTO” switch to “MANU”.

5. Sel: Select the working systems,

long press the button for 2s, will enter into 900M. then setting the gain.

then set the gain 65dB, long press the button for 2s again. 65dB was confirmed.

6. 900MHz: Show the current working system. Press “Sel” to change to the different system for operation.

7. AUTO/MANU: Automatic Mode or Manual gain Mode.

8. AGC: Automatic gain control with indicator.

9. ISO: Isolation inspection with indicator.

10. 63dB/68dB: gain of the working system.

11. 0dBm/0dBm: real-time outpower of the working system.

12. UL is Uplink, DL is the downlink. “+” is increasing the gain, “-” is decreasing the gain.



Line Amplifiers are specially designed to assist the Base Station (BTS) or Repeaters to compensate the system loss from in-building distributing cable, power splitter, and directional coupler and extend in-building signal coverage, and improve flexibility of in-building signal coverage system design

To meet the field strength requirements of the in-building signal coverage system.

The signal booster improves mobile signals with no negative impact on human health.



1. Isolation Inspection. When first power on the repeater, the device will automatically detect the isolation between the donor antenna and service antenna. The users could easier see the status and make the adjustment accordingly.

2. Input&Output Signal Strength Indication. The specific number of uplink and downlink measured in Output Power(dBm). Easy for users’ understanding.


3. Manual Gain Adjustment. The users or engineers could reduce the gain of the repeater manually via the buttons below the screen. The uplink and downlink gain could be set independently. “+” is increasing the gain, “-” is decreasing the gain.

4. Automatic Gain Control. Automatic Gain Control (AGC) is a dynamic gain adjustment feature with 31dB range.

5.Smart Mode = AUTO Mode.

6. MANU Mode, users can set the gain manually.

7. Auto Shut Down = ISO.
