Description
GlobaL application ATNJ factory 1800MHz 2G/4G signal repeater for your selection:
DCS 1800MHz 2G/4G Pico repeater is applied specifically in small area indoor DAS system. The base station signal is coupled and amplified by Pico repeater into in building system. The amplified signals is transmitted by indoor antenna. Meanwhile the indoor antenna receives the cell phone signal, and send the signal to the base station as uplink. This method can eliminate the signal dead spot, reject the interference, provide the stable signal communication for cell phone users. This Pico repeater mainly solves the problem spot problem in building. The coverage area is as large as 3000 square meters in open space, and 1000 square meters in partial obstacle area, 500 square meters in complete obstacle area. The edge power level for coverage area is above 85dBm. The repeater output power level is less than 20dBm.
Pico Repeater is a bi-directional amplifier that allows for the reception of signals, amplifies the signal and re-transmits into areas where there is no or very low signal level coverage enabling a mobile user to establish a call connection.
Pico Repeater can be deployed in indoor coverage and dead area. It is especially advantageous to use in 100M2-1000M2,which is a very economical solution. The output power is up to 20dBm per carrier.
Meanwhile, it can also boost the speed of GPRS.

Features:
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.
