3G UMTS Signal Amplifier

27dbm  WDMA 3G 2100mhz  signal repeaters 

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.
If you're experiencing dropped calls, slow or lost internet connection, stuck text messages, poor voice quality, weak coverage, low bars, and other cell phone reception problems, a cell phone signal booster is the best solution that produces definite results.
We provides signal boosters kits for any Homes, Offices, Cars, RV's, Boats and more. All amplifier kits come with Indoor and Outdoor Antennas, Cables, Power adapters and more.

ST-W27 WCDMA 2100mhz signal repeaters is to support any two mobile band existing in the world to help end users to improve mobile signals for much better phone call quality and smoother data transmission. It is designed to support coverage area max can up to 600 square meters with proper engineering. Below are the main features.

1. 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.

2. Manual gain control (MGC) available for both uplink and downlink to adjust the gain value for proper coverage during installation or maintenance.

3. To maintain safe and specific output signal levels and give alarms on self-oscillation, the repeater has built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.

4. Auto shut off function available for both uplink and downlink to avoid deep self-oscilation from jamming the towers, saving your trouble from operators. 

5.Wide band feature enables all devices operating within the wide frequency range of the repeater to see an improvement in performance.

6.Multiple phones and other handheld devices throughout a building can benefit from a wireless repeater.
7.Supports up to (500) users / calls simultaneously.

8.Extended phone battery life. (Your phone does not need to put out as much power due to improved reception.

The installtion of the Repeater
 
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 HPC-G27 Max can work with 8pcs indoor antenna.  ( when add antenna ,please remember to take splitters 
Installation steps 
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 Signal Repeater.
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.
 
Of course there are still a few more things to consider but in general, this is the basic procedure. For more information, please contact us.
