Dual band GSM/UMTS Mobile Signal Booster For 900/2100mhz 2g 3g Industrial Signal Booster Cellphone Signal Repeater


Cell Phone Booster Description:
Try making some test calls throughout the desired area of coverage while monitoring the LED’s to see if

it changes color. If you are showing strong signal strength but your calls are not going through, it could

be that you need to attenuate your Uplink a bit more. Keep in mind however that you do not want to

have more than a 5dB difference between the uplink and downlink values for optimum system performance.


Is it safe to use a cell phone repeater?
Everybody knows that mobile phones emit radiation that harms our health. The good news is that by using a cell phone repeater you can significantly reduce the level of radiation emitted by your phone. Additionally, every cell phone repeater from our store meets the international standards of CE and RoHS.


What maximum length of the cable can you recommend between an inside antenna and a cell phone repeater?
The length of the cable differs depending on the model of a cell phone repeater. For powerful repeaters such as 27dBm it is 15-20 meters;  for smaller ones such as 15dBm it is 5-10 meters. However, we strongly advise you to use the standard length of an inside cable in order to avoid signal loss.


Eliminate dropped calls and increase data speeds with a signal booster.
Indoor Dual Band Signal Repeater (Signal Booster) series is an ideal solution for both two wireless system in small/medium businesses and home users looking to enhance indoor wireless connectivity. It is connected via coaxial cable to Donor Antenna and Service Antenna, Donor Antenna is placed outside the building where it has easy access to BTS signal, and the Service Antenna is placed in the building where it can extend radio coverage to the blind area. And Automatic Gain Control (AGC) to avoid the Booster from over saturation, therefore maintaining a high voice quality and avoid adding interference to network. With good looking & super compact design also make it attractive. Besides, it is easy installation feature is also for individual customers to install the booster by themselves, and it does not need much professional knowledge and instrument.
Do not dismantle machine, maintain or displace accessories by yourself, because in this way, the equipment may be damaged or even get an electric shock.

Cell Phone Booster Features:

1. Cost effective solution for weak signal zones, reduce drop/off calls.

2. Compact size, low power consumption,

3. easy installation, great cover.

4. Expansion and extending of the signal of base station.

5. Optimization of the quality of the signal and source

6. Cover about 500~3000m² without block or obstruct.

7. High linear design, ALC function design, low interference to BTS.

8. Support any cellular devices (voice & data & video)

9. Wide band signal booster, or customize selective band booster.
