20dBm 900MHz&1800MHz&3G Tri Band Repeater/ Signal Booster /Cell Phone Extender (GW-20R-GDW)
China 20dBm 900MHz&1800MHz&3G Tri Band Repeater/ Signal Booster /Cell Phone Extender (GW-20R-GDW), Find details about China Tri Band Repeater, Signal Booster from 20dBm 900MHz&1800MHz&3G Tri Band Repeater/ Signal Booster /Cell Phone Extender (GW-20R-GDW)
A cell phone signal booster (also known as amplifier or repeater) is made up of three main elements - exterior antenna, amplifier, and interior antenna. They form a wireless system to boost cellular reception.
Features:
1. Cost-effective solution for weak signal zones, reduce drop/off calls.2. Compact size, low power consumption, easy installation, great cover.
Expansion and extension of the signal of the base station. Optimization of the quality of the signal and source
3. High linear design, ALC function design, low interference to BTS.
4. Support any cellular devices (voice & data & video)
5. Wideband signal booster, or customize selective band booster.
Advantages:
1. Smart Function, Intelligent mode setting
smart function called which can be activated via the front panel.
users can adjust gain and choose working band by LED panel, This smart function is easier than DIP Switch, can set up parameters, It is a simple, safe, and effective way.
2. Auto Level Control
The 30dB ALC is used to maintain steady output power even when the donor source signal fluctuates.
3.ODM/OEM service is available.
