70dB Mobile 3G Repeater Dual Band 900MHz 2100MHz Android Iphone
70dB Gain Metel Dual Band 2G 3G 4G Signal Booster 900/2100MHz Repeater Amplifier
General
The 900 / 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.

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
Product Description
With ALC AGC Function
Can control gain automatically. Avoid base station interference
(Band 8) 900MHz -- Uplink frequency : 890-915MHz/Downlink frequency
: 935-960MHz
(Band 1) 2100MHz -- Uplink frequency : 1920-1980MHz/Downlink frequency : 2110-2170MHz
Network support : GSM 2G + WCDMA 3/4G
Signal booster could be used for both phone calls and the latest LTE network at the same time. There is no limit to the number of mobile devices that can benefit from the improved internet.
You get all the accessories for installation and you don't need to buy anything else. Installation is simple and quick - it takes about half an hour and no special knowledge is required.

2. 20 meters cable
3. 5 meters cable
4. Indoor Ceiling antenna
5. Outdoor Log-periodic antenna
6. Power adapter
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.
We are manufacturer, and have our own factory.
