Black Color Five Band Cell Phone Signal Boosters N Connector with LED Display
Signal Booster Description:
Indoor Five Band Signal Repeater (Cell Phone Signal Booster) series is an ideal solution for three wireless systems 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.
The repeater improves mobile signals with no negative impact on human health.
Signal Booster Advantages:
Smart Function, Intelligent digital mode setting.
Smart function called which can be activated via the front digital panel.
will set up parameters more fast and more accurate,
It is a simple, safe and effective way.
Signal Repeater Feature:
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.
10. Support three wireless systems
11. Extended phone battery life. (Your phone does not need to put out as much power due to improved reception.)
12. Support all 2G,3G,4G bands(5 bands).
