27dBm Triple Band Mobile Phone Signal Booster GSM 900 DCS 1800 3G 2100
Booster for cell phone is an active amplifier based on an advanced power amplification technology.
SA-27-GDW is highly effective for poor signal areas such as big buildings, parking lots, tunnels etc.
It amplifies the signal within 5000 m2. It picks up even the lowest signal from the base station.
Indoor Tri 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.
Cost effective solution for weak signal zones, reduce drop/off calls.
Compact size, low power consumption,
easy installation, great cover.
Expansion and extending of the signal of base station.
Optimization of the quality of the signal and source
Cover about 1000~5000m² without block or obstruct.
High linear design, ALC function design, low interference to BTS.
Support any cellular devices (voice & data & video)
Wide band signal booster, or customize selective band booster.
Support three wireless systems
Extended phone battery life. (Your phone does not need to put out as much power due to improved reception.)
Digital Display Panel, Intelligent mode setting
Smart function called which can be activated via the digital display panel.
Users can choose gain and working system by LED Digital Panel.
Set the technical parameters simple and efficient, this is easier than DIP Switch.
|DC power problem
|Sys-1,Sys-2 or Sys-3, working in linearity
There are strong input signal or severe self oscillation.
Attention: input signal level is too high or the space of donor antenna and service antenna is not enough. please adjust the gain, If the red light still turning on that means over accepting of donor antenna or strong interference, then please adjust the place of donor antenna.
|Repeater breaks down, Please re-plug in and check if Alarm LED turns red, if it is, please take measures to keep Alarm LED green; if it maintains off, it means the power break down.
Digital display panel will show the real-time gain,
“+”increase gain,“-”decrease gain.
