Smart Dual Band Signal Booster GSM900 DCS1800 White Color 20dBm Power 70dB Gain
Today I will introduce you our intelligent mobile phone booster, it can be for wide single band and dual band. This smart cell phone booster SA-20I-GD is for dual wide band, it has high power 20dBm and high gain 70dB. This mobile signal amplifier boost GSM900mhz signals. It can be used for 2-4 rooms. It can cover about 2000m2 range. The GSM indoor mobile booster device has LCD display, you can see frequency, output power and gain on it when it works.
The LCD Repeaters have many intelligent functions: such as antenna isolation detection, Input & Output signal strength indication, system indication, manual gain control and smart mode. See the detailed introduction listed below:
The Display will auto off if don't touch it in one minute.
1. "Sacon Telecom" is Company LOGO. You can put your own company logo when you order, even for a sample.
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 30dB, long press the button for 2s again. 30dB 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. ISO: Isolation inspection with indicator.
10. 29dB/34dB: gain of the working system.
11. 0dBm/0dBm: outpower of the working system.
12. UL is Uplink, DL is downlink. "+" is increasing the gain, "-" is decreasing the gain.
1. Isolation Inspection. When first power on the repeater, the device will automatically detect the isolation between the donor antenna and service antenna. The users could easier see the status and make the adjustment accordingly.
2. Input&Output Signal Strength Indication. The specific number of uplink and downlink measured in Output Power(dBm). Easy for users' understanding.
3. Manual Gain Adjustment. The users or engineers could reduce the gain of the repeater manually via the buttons below the screen. The uplink and downlink gain could be set independently. "+" is increasing the gain, "-" is decreasing the gain.
4. Automatic Gain Control. Automatic Gain Control (AGC) is a dynamic gain adjustment feature with 31dB range.
5.Smart Mode = AUTO Mode. The repeater could automatically change the gain according to the specific environment when the smart function is on. Please note that when the SMART is on, users could not able to set the gain manually. Gain reduce 31dB automatically at first, then AGC Alarm RED when AGC control 5dB-10dB, ISO Alarm RED when AGC control 20dB-25dB, Repeater will Auto Shut Down. Auto restart after two minutes.
6. MANU Mode, users can set the gain manually. AGC Alarm RED when AGC control 5dB-10dB ;
ISO Alarm RED when AGC control 20dB-25dB, Repeater will Auto Shut Down.
Auto restart after two minutes.
7. Auto Shut Down = ISO. Auto Shut Down is a stage that temporarily stops the RF function. If the input power reduces to a safe range for the repeater to operate, the software would power the repeater back on and restore all functions promptly. However, if the input power remains too great and dangerous for the network, it will then shut down completely. In such case, the signal is too strong for the usage of the repeater.
