23dBm GSM900MHz 4G 1800MHz GSM Signal Repeater Booster 2g 3g
4g Mobile Phone Signal Booster 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 signal 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.Production
InformationAdvantages:1. Smart Function, Intelligent mode settingsmart 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 ControlThe 31dB ALC is used to maintain steady output power even when the donor source signal fluctuates.3.ODM/OEM
service is available.Features:1. "GREETWIN"is Company LOGO.2.
Power: Power supply with indicator.3. Smart: Smart function with
indicator. AUTO Mode now.4. M : "AUTO" switch to "MANU".5.
Sel: Select the working systems ,long press the button for 2s ,
will enter into 900M. then setting the gain.then set the gain 65dB,
long press the button for 2s again. 65dB was confirmed.6. 900MHz:
Show the current working system. Press "Sel" to change to the
different system for operation.7. AUTO/MANU: Automatic Mode or
Manual gain Mode.8. AGC: Automatic gain control with indicator.9.
