Specifications

Feature:
1)Wide Input Voltage:
Input DC Voltage Range 5-15V
2)  Self-oscillation Elimination:
The system detects self-oscillation, first reduces the link gain, then detects the loop, and finds that the self-oscillation is eliminated, the system returns to normal working state, otherwise, the power is turned off to prevent interference signal.
3)  Inactivity Mode:
When no user calls, the device works in standby mode, the uplink power amplifier is switched off, and the static power is decreased by 30%, so as to achieve the purpose of energy saving.
4) AGC (Automatic Gain Control):
When the downlink output signal is too strong or self-oscillated, the uplink and downlink can automatically reduce the gain and reduce the interference signal.
5) Automatic Power Shut-down:
When the self-oscillation happens, and the link attenuation value reaches 20dB, the MCU sends out the instruction and shut-down the PA.
6) 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 quality, data transfer quality, avoid the signal self- oscillation, and also very much reduce the interference to the cell tower, even if your house is very close from the cell tower, you don't need to worry about the interference and the trouble caused.

Twinkly YELLOW@ self–oscillation happen ,AGC is working,the attenuation value is more than 12dB

Continuous RED@ power supply is shut down


Note:
1. This booster only works for 800MHz. 0-1 bar outside signal may not be suitable for using it.Before ordering,please check your local signal frequency by calling network operator or checking on some sites.
2. For installation, you are supposed to pay attention to the following points:
1) There is seperate wall between indoor and outdoor antennas to make two antenna signal not interfere with each other.
2) To avoid interference, please make the distance of indoor and outdoor antenna more than 10 meters, let them not pointed at each other.


Package:
1. 1 * 70dB Booster Standalone
2. 1 * Power Adapter

FAQ:
1. What does a mobile phone signal booster include? How does it work? Can I use the signal booster when the outdoor signal has 0 bar?
    1) A signal booster kit mainly includes a signal amplifier ,an outdoor antenna(with a 10 meters coaxial cable ), and an internal antenna(with a 5 meters coaxial cable) etc.
    2) Outdoor antenna receives the signal from the base station to transmit to the repeater, the signal is boosted around the place via the indoor antenna to improve the call; It is suitable for transmitting the voice and data of mobile phone, tablet PC, or the Internet.
    3) Signal booster can only boost the mobile phone network signal, but does not help to generate any signal. For example, if your outside signal has 0 bar, it can not work or bring you any signal.

2. My outside signal only has 1 bar, the booster can bring me signal?
    Yes, it can. According to this situation, you need a higher dB gain booster (80dB gain)+ a higher dbi outdoor LPDA antenna+ a higher dbi indoor wall panel antenna. You can contact our customer service to get related information.

3. What do I need to know before ordering a signal booster?
    Before ordering, you need to know your network operator frequency. Every network operator has its own technology and frequency. The signal booster can only work well when it is suitable for your network frequency, otherwise it would not boost any signal.

4. I do not know my network frequency? How can I know it?
   Before ordering, you can search the frequency site or call your network operator to get information:
   Other choice: contact the customer service to provide related information to recommend.
    A. Tell us your network operator ,and it is used in which country.
    B. Tell us network current signal type(2g 3g or 4g)
    C. Tell us to use it to transmit voice or data

5. How can we do if we order the wrong frequency booster?
   You can contact the customer service to get the solution.

6. Why is my signal still same after installing the booster kit?
    A. The booster frequency is not suitable for your mobile phone network frequency
    B. The booster or the antenna is broken down

7. Mobile phone has full signal with booster, but can not make call or send message?
    Maybe it is the signal input and signal output interfere with each other. You need make sure:
    There is separate wall between indoor and outdoor antenna, so that the two antenna signal do not interfere with each other.
    Please try to change the direction of outdoor antenna.

8. What square meters signal will the booster cover?
    According to the house construction, material, outside signal, etc., it can boost signal as much as 2000 square meters. More information, you can contact the customer service.

9. About receiving the incomplete parcel?
    Please contact the customer service to solve, do not leave the negative feedback, open return or case request.

10. Why can I get a signal on my mobile phone outside but not inside of house?
    Houses are built with much reinforced concrete, roof is with heat shield , or the outside walls are backed with foil. That metal which is used in many construction materials or the metal construction acts as a total barrier for mobile phone signals. In this case, the signal booster can work and play an important role.

11. What is the difference of different outdoor antennas?
    For area with good outdoor signal strength, you will need the standard Omni directional antenna which does not need to be pointed at the local mast asit receives and broadcasts the signal in all directions, such as the omni tube antenna ,the fiber glass antenna, etc. If the outdoor signal is weak, you need the outdoor directional antenna which should be pointed to the base station to get signal, such as the outdoor yagi antenna, the outdoor LPDA antenna, etc.

12. What is the difference of different indoor antennas?
    The right angle antenna is the plug and play antenna, and it does not have cable, but convenient to install, suitable for the area around 100 square meters. The indoor ceiling antenna and the indoor wall panel antenna have 5 meters cables, more flexible, 4-6 of these antennas can be connected to one booster standalone to bring signal around 4-6 rooms, which covers signal around 2000 square meters, especially suitable for the large area such as factory, company office, multilayer building, etc.
