General


The 850/1900MHz 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

 

The repeater for mobile network 3G & 4G is used to amplify poor mobile Internet. The device features LCD screen guiding you through setup. It covers up to 3000 ft2, being effective for small private houses or other locations like offices, garages, shops, etc. The repeater amplifies signals at two frequency bands at the same time 850 MHz and 1900 MHz which are mostly used for providers in such countries as North and South America, Canada.

 

Among other distinctive and helpful features of JS-DB850/1900, 3G & 4G there are:

  • LCD screen showing outdoor signal and output value. The system will guide you through installation process and show you error tips with solutions. 

  • Automatic adjustment of gain and signal basing on the individual signal reception conditions.

  • Sleep mode helping to save energy when you do not use mobile 2G/3G/ 4G Internet.

How does it work?

 

1. RECEIVES SIGNAL

The powerful antenna reaches out to access a good signal, and delivers it to the booster.

 

2. BOOSTS SIGNAL

The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.

 

3. BROADCASTS SIGNAL

Your devices get increased cell reception, and calls and data are fed through the booster back to the network.
