You are probably wondering what a cell phone signal booster actually is. This is a common reaction that people have, and we are taking a moment to explain it to you. In the current age of mobile technologies, where the personal devices are wireless and private, every device is backed by a “backbone” wireless network carrier, which could be one of the many major carriers in the country, such as Vodafone. Over the years, the carriers have developed their infrastructure well and have been able to cover most of the country. But there are large parts of the country where the signal coverage is weak or reaches sparingly. This is where the cell phone repeater comes into play. They resolve calls data and LTE reception mainly. In terminology, we call correspondingly 2G 3G and 4G signal.
A cell phone booster is a device that gathers the signal from the air, usually through an outdoor unit (such as an antenna), and “conveys” this signal to an indoor unit that is supposed to boost the signal. This conveying is done through a wired connection between the outdoor antenna and the indoor unit. The indoor cell phone booster, in turn, is provided with external power through a power outlet and has a complex circuitry that allows it to amplify the weak signal that has been received by the outdoor antenna. The indoor unit then sends the electrical signal to the indoor antenna that is directly connected to the unit, and the antenna converts the electrical signal to waves of the same frequency as were received by the outdoor unit. This, the frequency range of the waves does not change, and the cell phones do not notice any difference, except for a dramatic increase in the signal power that they are receiving.
Thus, as we can see, cell phone signal boosters are devices that literally boost the cell phone signal that you are receiving. This is done through some complex circuitry that works through the use of external power and boosts the signal to usable levels.

Product Description
OUR Cellphone SIGNAL BOOSTER
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.
How it works?
1. Received a good outdoor signal from signal tower. 2. Cable transmits good signal to repeater. 3.Signal Booster enhance the received signal. 4.Improve indoor's cellphone signal.
