Gereral Introduction of Booster


1.What is the booster?


Cell phone signal booster(also named repeater, amplifier) is a product designed to solve the mobile phone blind signal. As the mobile phone signal is transmitted by electromagnetic waves to establish a communications link, however there are a lot barriers make it is unavailable to get sound signal. When people enter some tall buildings, some places basement malls, restaurants and parking lot, some places of enteretainment such as karaoke sauna and massage, some public place such as subway, tunnel and etc. Where cell phone signals can not reach, now the cell phone signal booster can solve these problems! The entire range of mobile phone signals can be well used; We all will get great convenience and benefit from sound signal.


Our boosters are the perfect solutions for a wireless improvement in the mobile reception!

2.Why need a signal booster?


Will you customers stay comfortable when there is no smooth communication in your shops,restaurants, hotels or clubs?


Will that be frustrating if your clients could not call you through due to weak signals in offices?


Will your life be inflenced if your mobile is always"out-of-service" at home when your friends call you?

How to install


70dB tri band mobile signal 3g 4g lte cell repeater B2 B4 B5 booster amplificador de seal celular 850 1900 1700/2100mhz Booster  


 


Step 1:Install the outdoor antenna in a suitable places


Step 2:Connect the outdoor antenna to the booster "outdoor " side by cable and connector


Step 3:Connect the indoor antenna to the booster "indoor" side by cable and connector


Step 4:Connect to the power

21st Checking Signals


The signal strength from the outdoor antenna directly affects the efficiency of the indoor coverage,so it is very important to choose the outdoor antenna location to get the best signals.



  • Select the top of building, the window or the balcony to install the outdoor antenna where there is with sound signal.

  • Testing the signal strength received from outdoor antenna by mobile phone from different direction,and it shall display full bar signals where the outdoor antenna installed.

  • Fix the outdoor antenna after selecting the best position,and adjust slightly its height or angles in order to get the best signals.

  • The phone calls or data transmission shall be smooth and stable by 3 times testing where the outdoor antenna installed.

FAQ


 70dB tri band mobile signal 3g 4g lte cell repeater B2 B4 B5 booster amplificador de seal celular 850 1900 1700/2100mhz Booster  


 


1>After installing the booster,but no effect


Solution:



  • Check whether you got the booster with correct frequency.For example, the GSM900MHz frequency can not works for the DCS1800MHz.

  • Check the signal outside received is enough, the total input power level shall be around -50dBm, lowest shall be more than -80dBm.And check the LED of DL whether it is RED.

  • Check all the installation is correct, and all the accessories are well connected, check the LED of ALA is RED.


2>After installation, there is full bars signal,but can not make or received a call.



  • The Downlink is very well,but the Uplink is can not send the signal back to BTS. Need to check the cables and connectors are well connected indoor.


3>After installation, there is full bars signal ,but will turn 0 bar when make a call.



  • There is self-oscillation.The isolation between the outdoor antenna and indoor antenna is not good enough,try to adjust the antennas'directions or enlarge the distance between them.


4>After installation, the signal is very sound,but there is noise when mark calls.



  • The indoor antenna and mobile are too close,and cause interference,try to keep the mobile a litter far away from indoor antenna.


5>What is AGC function? And what is the advantage?


AGC means Auto Gain Control; it means the booster can control the gain by itself according to the surroundings.



  • When there is a sudden strong signal input,the booster can adjust the gain accordingly to protect the booster module together BTS station, make the strong signal will not affect the BTS after adjustment.

  • When the signal outside is too weak, the booster can adjust the gain to full stage to booster the signal received at most for end use.

  • The AGC repeater is with LED on it,it can directly show the running state of the booster.


6>What is MGC function?And what is the advantage?



  • MGC function means Manual Gain Control

  • When your outdoor signal too stronger, so the repeater can not work well and have noise , so you can adjust the Gain by yourself.


7>What is AI function?And what is the advantage?


AI means Artificial Intelligence



  • The booster is with CPU inside,it can control the gain more intelligence according to surroundings than AGC function.

  • The booster with AI is energy-effective.When there is no call.the booster will change to a "Stand-By"state, thus can save a lot power.

  • The boosters with AI function have ALA LED on it, and it can easily help to find out the problem when setting and running.


8>Will the repeater increase the RF radiation?



  • No.it will decrease instead.

  • When the signal is bad, the BTS will "Order" the mobile phone to increase its output power in order to ensure find connection,there will be strong mobile output power level when the mobile signal bar is less, and stronger mobile output power level means stronger radiation.
