Audited Supplier Movable Central Frequency Cell Phone Signal Repeater 23dBm 3G 2100MHz
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.
A cell phone reception booster is generally a repeater system that involves the amplifier adding gain or power to the reception in various directions. Even for a cheap cell phone signal booster, maximum gain differs by application. The work of an outside antenna is to both receive and transmit signals to a cellular tower with enhanced power and sensitivity. Usually, the dB gain is never below 7 dB and can be over 10 dB gain. The system's elements conduit is the coaxial cable. It is also a factor in transmission loss.
The main aim of the cellular phone signal booster is taking the existing cell phone signal around your car, office, workstation, or home and amplifying it. After amplification, the signal is rebroadcasted to the area with no reception or weak signal. Apart from consisting of an amplifier to boost the reception, external antenna, and internal antenna, there're cell phone boosters with indoor antenna and amplifier as a single unit making them superb indoor cell phone signal boosters. In most cases, the three components are detached. Other optional components include the Attenuator (reduces unwanted frequency signals), Lightning Surge Protector, Splitter, and Tap.
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.
6. Support System CDMA800, GSM, DCS, PCS, WCDMA, LTE 4G, etc
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.
