Cell phone signal repeaters provide the ultimate solution in any area where cellular communications are not functioning properly due to signal leakage. The repeater is easy to install and operate, with built-in indoor antenna and no interference. It can also improve the indoor electromagnetic environment, extend mobile phone battery life and reduce mobile phone radiation. Cell phone repeaters are very suitable for home and office use.
How do boosters/repeaters work?
Repeaters are designed to achieve one main principle: to fill areas with weak or poor signals and amplify those weak signals to provide you with the communication that is right for you.

Describe the steps in which Repeater works.
1) The external antenna receives the signal from the nearest mobile base station.
2) The external antenna sends the received signal via coaxial cable to the installed repeater.
3) Repeaters accept low signals and improve them.
4) The improved signal goes to the internal antenna by connecting the coaxial cable.
5) Built-in antenna sends improved and good signal to your phone.

Installation method
- Secure the outdoor antenna reception to the roof and point it toward the cell tower.
- Connect the outdoor antenna to the repeater's "outdoor" port via a cable.
- Also connect the indoor antenna to the repeater's "indoor" port via a cable.
- Plug the power adapter into an AC outlet and complete the installation.
Technical Support
- If you still do not receive a signal after activating the relay, please check whether the outdoor antenna is pointed at the signal tower or somewhere else with a strong signal, and check whether the strength reaches -70DBM.
- If the call cannot be made, adjust the direction of the outdoor antenna.
- If the strength is unstable, check whether the outdoor and indoor antennas are too close. Please ensure that the distance between the outdoor and indoor antennas is at least 20 meters, with a wall in between and not on the same level (the outdoor antenna can be one level higher than the repeater and indoor antenna).
- Indoor antennas and repeaters are best located at least 4 meters away from nearby doors and windows.
When using this product to amplify the signal, the outdoor signal should be as good as possible. If our outdoor signal is poor or poor, the product will not work properly.
If the indoor signal is always low, but the outdoor signal is great, then the repeater will work fine.If the indoor signal is sometimes full and sometimes not full before installation, this environment is not suitable for installing a repeater.
Reasons to Buy a Cell Phone Repeater.
1) Signal repeaters provide a well-organized service, which is why the connection quality will be very good after installing the system.
2) Signal repeaters don't require extra wires to be connected to your phone, so you can use your phone without any extra troublesome accessories that, in other worlds, require no physical connection to your phone.
3) Practical, beautiful and easy to install. You don’t need to hire anyone to provide installation of the equipment. You can install it yourself simply using the manual list that comes with the repeater.
4) The system can be used with multiple mobile phones. All phones within range and suitable for your repeater frequency can use the amplified signal.
5) Signal repeaters can cover different coverage areas from small to large. In this case, you can decide which of our repeaters is suitable for your office or supermarket.
6) The repeater works in full duplex. This means they don't just receive a weak signal from a mobile base station, which is then passed through an amplifier and transferred to the phone. They also receive signals from your phone and send them to mobile base stations.
7) Our equipment is completely safe. Mobile repeaters do not produce any radiation.
Repeaters can boost the signal in places with poor signal coverage, such as:
1) Underground areas: basements, parking lots, tunnels;
2) Other places where cellular signals are blocked by metal or concrete walls: offices, supermarkets, cinemas, hotels;
3) Places far away from BTS, such as private residences.
