Detailed Product Description

Dual Band 70dB 4G Signal Repeater Mobile Phone Network Extender

850/1700MHz 2G 3G 4G Dual Band Signal Repeater Mobile Phone Signal Extender Booster Amplify

General
The 850/1700MHz 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

Selling Point

1. Intelligent to guide the installation with LCD

2. Real time display the signal strength.

3. Automatic dormancy when no user make the calling

4. Automatic alarm when installation mistake and provide the according solution

5. Automatic adjust the system gain to avoid the repeater self-excitation

6. Initiative reminding when the device was damaged.

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.

Packaging Including:

1. Dual Band Booster

2. 20 meters cable

3. 5 meters cable

4. Indoor Ceiling antenna

5. Outdoor Log-periodic antenna

6. Power adapter

Installation Approaches

1.Fix up outdoor antenna reception on housetop and point to signal tower;

2.Connect outdoor antenna to “outdoor” port in repeater nachine through cable;

3.Connect indoor antenna(s) to “indoor” port in repeater machinethrough cable also;

4.Plug power adaptor into AC power socket and finish installation.
