Detailed Product Description

Dual Band 850MHz 1900MHz 3G Signal Booster 70dB Cell Phone Repeater

70dB Gain Dual Band Cell Phone Repeater 850 / 1900MHz 2G 3G 4G Signal Booster Amplifier

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

1. Smart LCD : Show the real-time signal strength.

2. Sleeping Mode : When no user calls, the device works in Sleeping mode, so as to achieve the purpose of energy saving.

3. ALC(Automatic Level Control) : Automatically adjust the output gain down to optimal figure while the output gain is above the optimal figure by the ALC circuit, this can greatly optimize the calling and data transfer quality.

4. AGC (Automatic Gain Control) : When the downlink output signal is too strong or self-oscillated, booster can automatically reduce the gain and reduce the interference signal.

5. MGC (Manual Gain Control) : In order to install the booster conveniently, all frequency band of the booster have the Gain attenuation adjustment function, the adjustment scope is 0-27dB.

Product Description

Accessories

a. Dual band signal booster;

b. Indoor Ceiling antenna;

c. Outdoor Log-periodic antenna;

d. 20meter outdoor cable and 5meter indoor cable;

e. User manual;

f. Power adapter.

Installation:

The booster is fixed onto the wall through expansion bolts.
A. Drill holes on the targeted place and install expansion bolts.
B. Align the holes with the expansion bolts, place flat washers, spring washers, and nuts in turn, and tighten the nuts to fasten the installing support.
C. Place the booster on and fasten it.
D. Connect cables and power cables to the booster respectively.
E. After installing the booster as described above, power on the booster to check the operation status.

Connection:

A. BTS Port : donor antenna cable is connected with Outdoor Port;
B. MS Port : service whip antenna is connected with Indoor Port;
C. DC IN : connected with Power adaptor.

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.

FAQ:

1. Are you trading company or manufacturer ? Could I use our own logo and label?

We are factory, with trading service. We provide OEM/OEM service.
