Outdoor Repeater 850mhz Output 5watts
Product introduction
1.Product summary
850mhz frequency-selecting micro repeater working for indoor or outdoor communication service blind area, it receives the base station's signal through the wireless mode to distribution system, and through a small base station antennas to send signals amplified out, meanwhile, mobile phone signal receiving, and go to the base station through the distribution system uplink, it can avoid communication service blind area indoor and outdoor effectively, barrage jamming, To provide stable and reliable signal for users in blind area, Enable users to enjoy the personal communication service with high quality. It is mainly used to cover the blind signal, poor call quality, slowly online rate and so on.
2.Place of application
Residential, office buildings, shopping malls, bars, underground parking, elevator and other communication blind area.
3.Characteristic function
Simulation of ALC
Wireless micro repeater with simulation of ALC function，gain automatic dynamic adjustment range up to 20dB, ensure the system with high reliability and high stability.
Function of Self-excitation detection
In the process of 850mhz micro repeater installed，it will be automatic detection, isolation between the donor antenna and the retransmission antenna, if the isolation does not meet the requirements of system installation, equipment malfunction indicator lamp providing instructions, and automatically reduce equipment gain, or shutdown. Until the device is working properly, protecting the safety of equipment and network without interference.
The function of Uplink and Downlink gain automatic linkage
After the System is installed and started, the system will automatically detect the input power, and control the output power, then calculate the downlink gain, automatic adjustment of uplink gain, maintain amplification balancing of system, realize uplink and downlink gain automatic linkage debugging, the gain of automatic control system is less than signal attenuation in path, ensure there is no any interference noise take into network.
Automatic installation indication function
The perfect working state indicator, 850mhz micro repeater different work state can be a good indicator. The installation is simple, to identify more clearly.
Local monitoring attenuation settings
Setting the equipment ATT digital attenuation in under the 850mhz system using local monitoring software according to the field applications , to adapt to the installation site due to gain strength of different requirements, make the application more convenient
