800MHz 900MHz Dual Band Repeater 2G 4G Cellular Cell Phone Repeater
Dual Band Repeater 70dB Gain 800 / E900MHz Mobile Signal Booster 2G 4G Cellular Amplifier
Selling Point
2022 new upgraded Micro power smart single band signal repeater for residential use with WIFI monitoring and control function, it could cover 100- 300sqm (standard kit), and could support max 2 to 3 indoor antennas to cover over 800sqm. Analog repeater and Digital(Customized Selected Band) repeater for choice.
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:
The amplifier 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.
