Усилитель сигнала Kingtone 3G 4G B5/4 двухдиапазонный GSM Мобильный сетевой ретранслятор

what is the mobile signal booster?

Mobile signal booster is a product designed to solve the mobilel phone blind signal. As the mobile phone signal is transmitted by electromagnetic waves to establish a communication link, however there are a lot barriers make it is unavailable to get sound signal. 850/1700MHz signal booster easy installtion & operation, mini size, light weight, no interference to the base station and no harm to people health. It is suitable for home, office etc.

Step 1 Start by taking your phone up to the roof or other location outside to find where the signal is strongest.

Step 2 Temporarily mount the Outdoor (outside) antenna in that location. You may need to adjust and move the antenna later. 

Step 3 Run coaxial cable into the building to a convenient loaction (attic, etc.) where you can also get standard power for the  3G Signal Booster .

Step 4 Place the Signal Repeater in that location and connect the coaxial cable to the Outdoor Side of the Signal Repeater and the Outdoor antenna.

Step 5 Mount your Indoor (inside) antenna in a productive location. You may need to adjust or move the antenna later. More notes on Indoor antennas and patterns here.

Step 6 Connect coaxial cable between the Indoor antenna and the Signal Repeater output port.

Step 7 Power up the system and check for signal inside the building. If needed, tune system by moving and or pointing the Outdoor and Indoor antennas until they get the most signal possible.

Step 8 Secure all antennas and cables, securely mount the Signal repeater and clean up the installation.

Step 9 Plug power adaptor into AC power socket and finish installation

The mobile signal booster makes the signal stronger and more stable in place with weak signal coverage such as:

Basements, packing lots, tunnels, offices, supermarkets, cinemas, hotels, villa, bar, ktv, places distant from the BTS like private houses etc.

Package Included:

1.Mobile signal booster x1
2.Power Adapter x1
3.English User Manual  x1

Note : The product is not including cable,outdoor antenna,indoor antenna,you need to buy extra.

Before buying please note:

1.check your frequency, because different Phone Providers operate on different frequencies and the booster can only work on correct frequency.

2. Make sure that you can place calls on the outside of your home, in the attic, at roof level or wherever you plan to place the Outdoor Antenna. Because the mobile signal booster cannot produce a signal, only amplify a weak one.

Since 2006, Kingtone has been developing and manufacturing Repeaters included CDMA Repeater, GSM Repeater,DCS Repeater, PCS Repeater, UMTS(W-CDMA) Repeater, Tetra Repeater, iDEN Repeater, Wimax Repeater and 4G LTE Repeater etc. Moreover, Kingtone Repeater have different types included Full Band-selective Repeater, Channel-selective Repeater, Frequency-shifting Repeater, Fiber-optical Repeater, Trunk-amplifier etc. The repeaters can be Single-band Repeater, Dual-band Repeater and Tri-band Repeater etc. The Multiple Bands for different Mobile Operators.

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.
