A cell phone signal booster (also known as cellular repeater or amplifier) is a device that boosts cell phone signals to and from your mobile phone whether at home or office or in any vehicle.
It does this by taking the existing cellular signal, amplifying it, and then broadcasting to an area in need of better reception.
A booster kit includes an booster, an indoor antenna and an outdoor antenna, the outdoor antenna can pick up good mobile signal from outside of your house, and send the signal through coaxial cable to the booster, the booster can amplify the signal, then the amplified signal is sent to the indoor antenna, the indoor antenna can transmit the signal into your house, so you can enjoy clearer phone call or faster mobile date inside your house.
The consumer repeater is an ideal solution for providing a cost effective improvement in cellular in-building coverage of a home, office, restaurant or building, in the quickest time possible.
Preparing to Buy a Booster:
1. Check your frequency, because different Phone Providers operate on different frequencies and the booster can only work on correct frequency.For more detail, refer to www.unlockonline.com/mobilenetworks.php
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. Phonetone can only bring signal into your home when signal reaches the Outdoor Antenna. If there is no signal, the Phonetone will not work for you.
Main features
Main Features:
1. With unique appearance design, have good cooling function
2. With MGC function,(Manual Gain Control), Customer can adjust the Gain as needed ;
3. With DL signal LED display, help to install the outdoor antenna at the best state;
4.With AGC and ALC, make repeater work stable .
5.PCB with isolation function ,make UL and DL signal not influence each other,
6.Low intermodulation, high Gain ,stable Output power
Application Scenarios
Outdoor antenna ( for receiving the signal from the BTS ) + Cable ( transfering the received signal) + Repeater ( for amplifying the received signal) + cable( for transfering the amplified signal) + indoor antenna( for shooting the amplified signal)
(Note : Omni indoor antenna is 3dBi,it can work with about 200m2 . If need repeater coverage larger area , need add moreantenna,the KT-4G27 Max can work with 8pcs indoor antenna. ( when add antenna ,please remember to take splitters )
Installation Approaches:
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
