General
The 1800/2100MHz 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
Model No : JS-DB1800/2100/P
Can control gain automatically. Avoid base station interference
(Band 3) 1800MHz -- Uplink frequency : 1710 - 1785MHz / Downlink frequency : 1805 - 1880MHz
(Band 1) 2100MHz -- Uplink frequency : 1920 - 1980MHz / Downlink frequency : 2110 - 2170MHz
Network support : WCDMA 3G + DCS 4G
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.
Note : Please be sure the place where you are going to install is WCDMA 2100MHz and DCS 1800MHz And make sure you can get at least 2 bars 3G and 4G signal of outdoor before you buy, otherwise this product can’t help you. It needs outdoor good signal to improve your indoor signal.
Please Check Frequency before Buying How to check?
- Android mobile phone
Download App called < Network Cell Info Lite >
The App will tell the number of LTE band
- Iphone
Dial *3001#12345#*
Clink Cell Serving Info
Check Freq Band Indicator, the number is LTE Band
Item Description
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.
