Product Description

2G 3G 4G Cell Phone Booster Amplifier Dual Band 850MHz 1800MHz

 

850/1800MHz 2G 3G 4G Signal Booster Dual Band Cell Phone Network Repeater Amplifier

 

General
The 850/1800MHz Pico Repeater provides an affordable solution to solve the indoor signal coverage problems due to signal fading and attenuation caused by architecture obstacles. And its easy installation and maintenance can help carrier get fast return.
The repeater is working as a relay between the BTS and mobiles. It picks up the strongest signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Indoor Signal Distribution System to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.

Selling Point

 

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 signal 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.

 

Compact size and high-tech design.

The signal amplifier has a small size, light weight, advanced design and intelligent LCD display. It fits perfectly into any interior.

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.
