为什么要购买手机信号中继器/信号放大器/ GSM放大器：
手机变得特别有用的，当人们进入临界状态。 在紧急情况下及时调用可以拯救别人的生命。
遗憾的是，仍然有一些地方，人们可以发现自己“不在服务区”。 通常那些地方或者是从蜂窝电话基站太远或位于内部的地下建筑物，例如：
`停车场，隧道
`大商场，办公楼
`车，船等。
`家在偏远地区等
如何为手机信号直放站GSM / DCS / 2G / 3G / 4G的工作？
外部天线捕获来自移动基站的低信号并将其传送到蜂窝电话
放大器通过连接电缆（同轴）。
后的信号被放大器电话接受，该设备它放大。
然后该放大的信号通过连接电缆（同轴电缆）向内侧天线。
在这之后，将放大的信号发送到蜂窝电话。
一个普通的GSM直放站包括：
12分贝室外天线
3分贝室内天线
RG6-50 OHM户外同轴电缆-10M
安装附件
交流电源

手机信号放大器的特点
A.高增益线性功率放大器
B点。 ALC和AGC功能的技术。
C.超低噪声接收放大器
D.有向基站没有干扰，原系统的开口和基站，而不需要调整参数之后。
E.稳定可靠的电磁兼容设计。
F.基站剂量不会引起增加的背景噪声，但不会导致在基站的通信质量的下降
G.使用全双工通信模式。
H.散热有效合理，结构相当，体积是合适的。
信号中继器安装图（非常方便，易于安装）
你应该如何安装中继器（很容易和简单）：
第1步：用你的手机来测试屋外或屋顶上的信号强度，-70dBm是基本要求（满吧）。
步骤2在该位置安装室外天线和不断调整，其指向信号塔站，试图得到最佳的信号。
第三步：运行室外同轴电缆为建设一个方便的位置与信号中继器连接。
第4步：安装你有信号转发室内天线
第5步：上电信号中继器设备内部检查信号，移动的室外天线，直到你获得满意的信号。
注：连接室外（BTS）端口与室外天线，室内天线连接室内ANT（MS）端口，室外天线安装在一个较高的位置。 两个天线应为10米远离彼此至少。
室内和室外天线必须由墙隔开。

Why we should buy mobile signal repeater/ signal booster/ GSM amplifier :
Cell phone becomes especially helpful when people get into critical situations. In case of emergency a timely call can save somebody's life.
Unfortunately, there are still some places where one can find themselves 'out of coverage'. Usually those places are either too far from the cell phone base station or located inside underground constructions, for example:
` Parking lots, tunnels
` Big stores, office buildings
` Cars, boats etc.
` House in remote areas etc
How is mobile phone signal repeater GSM/ DCS/ 2G/ 3G/ 4G WORKING ?
The outside antenna catches the low signal from the mobile base station and delivers it to the cell phone
amplifier through the connection cable (coax) .
After the signal is accepted by the phone amplifier, the device amplifies it.
Then this amplified signal goes through the connection cable (coax) to the inside antenna.
And after that, the amplified signal transmits to the cell phone.
A regular repeater GSM consists of:
12dB outdoor antenna
3dB indoor antenna
RG6-50 OHM outdoor Coaxial Cable-10m
mounting accessories
AC power supply

Features of mobile phone signal amplifier
A. High-gain linear power amplifier
B . ALC and AGC function technology .
C. Ultra-low noise receive amplifier
D. There is no interference to the base station , right after the opening of the original system and the base station without the need to adjust parameters .
E. Stable and reliable electromagnetic compatibility design .
F. The base station dose not cause an increase in background noise , but will not lead to a decline in the quality of the base station communications
G. With full-duplex communication mode .
H. dispel the heat effective reasonable , the structure is pretty , the volume is suitable .
Signal repeater Installation diagram (very convenient and easy to install)
How should you install repeater (very easy and simple) :
Step 1: Use your mobile phone to test signal strength outside house or on roof, -70dbm is the basic requirement (full bar) .
Step 2 Install outdoor antenna in that location and keep adjusting, point it to signal tower station, try to get best signal.
Step3: Run outdoor coaxial cable into building in a convenient location to connect with signal repeater.
step 4: Mount your indoor antenna with signal repeater
step5: Power up signal repeater device to check the signal inside, moving outdoor antenna until you get satisfied signal.
Note: Connect outdoor (BTS) port with outdoor antenna, connect indoor ANT (MS) port with indoor antenna, outdoor antenna is mounted at a higher position. Both antennas should be 10 meters far away from each other at least.
Indoor and outdoor antenna must be separated by wall.
