LCD Display Dual Band Cell Phone Amplifier Kit EGSM 900 1800MHz Speed 2G / 4G
LCD Display!Dual Band EGSM900+1800MHz Speed 2g/4g Cell Phone Amplifier Kit
Mobile signal repeater 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.
Dual band signal booster is supplied as a complete set, which, in addition to the amplifier, contains internal and external antennas, cable, brackets and a power supply. Installation usually takes about 15-20 minutes and does not require any special technical knowledge. Only after you have installed the amplifier and antennas and connected them with cables, you can turn on the system. Please note, however, that cables longer than those included in the kit may adversely affect the repeater's amplification capability. Within seconds. Once switched on, the repeater will provide the entire area with a reliable GSM, EDGE and GPRS signal.
Selling Point

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
Note : Please be sure the place where you are going to install is EGSM 900MHz DCS 1800MHz And make sure you can get at least 2 bars 2G and 4G signal of outdoor before you buy, otherwise this product can’t help you. It needs outdoor good signal to improve your indoor signal.
