Model:GW-27L
4G Mobile Signal Repeater Description:
Cell Phone Signal Amplifier is suitable for small Flat which has
2-4 rooms with 80dB Gain, It can support ultra wide band including
2G,3G,4G. And improve your cell phone signal level In mobile
communication, it is inevitable that macro-cell covere caagnnot
cover weak or dead zones; to use repeater is a good choice in these
areas. These band selective repeaters mainly applied in covering
small blind and weak zones.
The LCD Repeater covers all existing wireless public communications
networks:
LTE2600MHz
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: outpower of the working system.
12. UL is Uplink, DL is downlink. “+” is increasing the gain, “-”
is decreasing the gain.
4G Mobile Signal Repeater Features:
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. The repeater could automatically change the gain according to the
specific environment when the smart function is on. Please note
that when the SMART is on, users could not able to set the gain
manually. Gain reduce 31dB automatically at first, then AGC Alarm
RED when AGC control 5dB-10dB, ISO Alarm RED when AGC control
20dB-25dB, Repeater will Auto Shut Down. Auto restart after two
minutes.
6. MANU Mode, users can set the gain manually. AGC Alarm RED when AGC control
5dB-10dB ;
ISO Alarm RED when AGC control 20dB-25dB, Repeater will Auto Shut
Down.
Auto restart after two minutes.
7. Auto Shut Down = ISO. Auto Shut Down is a stage that temporarily stops the RF function.
If the input power reduces to a safe range for the repeater to
operate, the software would power the repeater back on and restore
all functions promptly. However, if the input power remains too
great and dangerous for the network, it will then shut down
completely. In such case, the signal is too strong for the usage of
the repeater.
Applications:
1) Donor antenna: Recommend to use wide band panel antenna (7~14dBi gain) or Yagi
antenna, better to use antenna with good direction, high gain, and
decoration shall be considered if it is in urban areas.
2) Role: It picks up signals from the tower, and sends to the booster
through cables, at the same time, it transmits the amplified mobile
signals from the booster to the tower.
3) Server antenna: Recommend to use indoor omni or panel antenna. Indoor omni is
suitable for wide open areas where the signals can be radiated from
the center to the surroundings, while indoor panel is suitable for
those narrow and long areas, like tunnels, corridors, elevators,
etc.
4) Cables: 5D-FB or 7D-FB coaxial cables.
5) Power supply: Booster power adapter, a desktop standard. Usually directly
connected to a power outlet. But preferably equipped with an air
switch, groundings, sometimes a surge arrestor shall be connected.
