Before ordering,please note!!!
1.make sure your cellphone can receive signal better than -75dB(GSM),-85 dB(3G) or -95dB(4G) outside your house, which should shows 3~5 bars. If your cellphone only show 0~1 bar, we do NOT suggest you buy booster.
2.Please check your frequency first,the booster's frequency is 900MHz 1800MHz 2100MHz , Band8,Band3,Band1
3.Make sure the frequency band of your carrier is suitable for this item.Otherwise the device can't work for you.
There are some ways to check the frequency:
(Frequency doesn’t match, the signal booster can’t works.)
1. Turn on the network (2G/3G/4G) you want to amplify and go to outdoors of your house
2.Install an app: Network cell info Lite, and show the screenshot to us.

Installation Steps:
1.Fix up outdoor antenna reception on housetop or the high place and point to signal tower .
2.Connect outdoor antenna to repeater machine ''BTS" port via cable.
3.Connect indoor antenna to repeater ''MOBILE " port .
4.Plug AC power cord into power source and finished.
5.TIP: An outdoor antenna should be "isolated" from the internal antenna, that is, there must be constructive obstacles (walls, partitions, etc.) between the antennas.
How to check the signal strength?
It can check on your smart phone , firstly , please click the “ setting guis” then press “ about phone “ , to “ network guis” , then you can see the words is about network , signal strength , after that please press into , then you can check the signal strength from your side , finally , confirm the signal strength you can fixed your outdoor antenna .
Normally, the signal strength more than -70dbm, -65dbm is best can receive the signal.
What condition needed to fit outdoor and indoor antenna?
Need wall blocking between outdoor and indoor antenna , it’s better off far from each other till can not see face to face directly, otherwise will cause self-excitation , which is you can see in full signal but couldn’t communication smoothly or dropping calls.
Solution for signal problem after installation and technique supporting
1. If the signal still weak after installation, please check if outdoor antenna point to the signal tower direction correctly.
2. If still no signal after installation, please check the repeater power adapter whether connected perfectly? And make sure all the connectors connect well.
3. If strength is not steady as expected , please check if outdoor and indoor antenna was too close, It’s vital that outdoor antenna must far away from the indoor antenna at least 10 meters, it should with a barrier and not in horizontal line while installation .
Please wrap the outdoor connector by waterproof glue, otherwise will reduce signal strength if in humid situation.
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.
