Dual Band 70dB Gain Mobile Range Extender Bi Directional Amplifier
LCD Display Dual Band Repeater 2G 3G 4G 900 / 2100MHz 70dB Mobile
Signal Amplifier
Selling Point
Pico Repeater is a bi-directional amplifier that allows for the reception of signals, amplifies the signal and re-transmits into areas where there is no or very low signal level coverage enabling a mobile user to establish a call connection.
Pico Repeater can be deployed in indoor coverage and dead area. It is especially advantageous to use in 100M2-1000M2,which is a very economical solution. The output power is up to 20dBm per carrier.
Meanwhile, it can also boost the speed of GPRS.
The advantages of this dual band repeater include:
LCD Display.
Even a non-technical person can easily install and use this signal
booster. The display shows all important information and prompts:
input and output signal strength, installation details, power, AGC
(automatic gain control), etc.
Sleep Mode.
In the absence of incoming and outgoing calls and data transmission
over the Internet, the LCD amplifier goes into sleep mode. This
function helps to save energy.
Automatic Adjustment Of Operation.
Dual band repeater can adjust the system gain and signal
level. All this helps to avoid self-excitation of the device. If a
problem occurs, the device will turn off automatically.

The repeater makes the signal stronger in places with poor signal
coverage such as:
1) Underground areas: basements, parking lots, tunnels;
2) Other places where cellular signal is shielded by metal or
concrete walls: offices, supermarkets, cinemas, hotels;
3) Places distant from the BTS like private houses.
