850MHz 1800MHz Dual Band Signal Booster 2G 3G 4G Network Repeater


Dual Band Signal Booster Repeater Network 2G 3G 4G 850 1800MHz 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.

Product Description


1. How Booster/Repeater Works?

Repeaters are designed to fulfill the idea of one and main principle: to fill the areas with the weak or bad signal and to amplify these low signals in order to provide you with the communication suitable for you.


1) The outside antenna receives the signal from the nearest mobile base station.

2) The outside antenna sends the received signal through the coax cable to the installed Repeater.

3) The repeater accepts the low signal and improves it.

4) The improved signal goes to the inside antenna through the connection coax cable.

5) The inside antenna send the improved good signal to your mobile phone.


2. 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.
