5watts 850MHz Outdoor Signal Repeater Waterproof
Outdoor Repeater 850mhz Output 5watts Product introduction 1.Product summary 850mhz frequency-selecting micro repeater working for indoor or outdoor communication service blind area,Website:, 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 Specification Frequency 850mhz: 850mhz 824-849mhz ?869-894mhz Output power TX: 35dBm?2dBm RX: 37dBm?2dBm ALC control When in max output power, if increased less10dB input Level, the variation of the output power can be controlled within 2dB , When in max output power, if increased over10dB input Level, the variation of the output power can be controlled within 2dB or shut down repeater Gain 85?2dB Gain control range ?30dB Gain control step and error Gain control step?1dB Error range?0?10dB, error ??1dB? 10?20dB ,error??1dB? ?20dB, error??1.5dB Ripple in band ?2.0dB/3.84MHz?peak value??Ripple in band?4.0dB Frequency error ??0.01ppm Spectral emission Meet 3GPP TS 25.106 demand ACRR Meet 3GPP TS 25.106 demand Spurious emission Meet 3GPP TS 25.106 demand Outputintermodulation Meet 3GPP TS 25.106 demand Vector range error EVM?12.5% PCDE ?-35dB Noise figure ?6.0dB Insulation test and prevent self-excitation Support Time delay ?5.0us VSWR ?2.2 Ripple out of band 2.7MHz?f_offset?3.5MHz?70dB 3.5MHz?f_offset?7.5MHz?70dB 12.5MHz?f_offset?35dB 4.Indicator lamp status table Work indicating lamp Statu Instruction Power indicator lamp (Power) Bright The power supply is normal Go out Power failure Downlink indicator lamp?DL/P? Go out Output power is too low Twinkle The output power is normal Alarm indication lamp?Alarm? Twinkle Isolation is bad or antenna is not installed good Go out Normal work Uplink indicator lamp?UL/P? Twinkle The output power is normal Go out Output power is too low Product installation? Installed in the irrelevant personnel can't contact easily? Installed in the cloth feeder and power supply easily? To avoid the heat environment, installed in the ventilation? Installed on the vertical wall or mast, to ensure good heat dissipation? Wall-mounted installation mode, fixed the product bracket on the back of the installation , bracket hole location and expansion screw holes align fixed to the wall fixed hole a relative position as shown below; Mast mounting mode, fixing the equipment bracket on the back of the product , using the hoop through the mounting bracket and fasten on the pole; ? ? ? ? ? ? ? ? ? ? ?90.5mm 266.0mm You can power up the product after the installation is complete, after all four indicator light on for 1 second, then after they all turn off, end, indicator lamp status in normal indication mode.? Repeater Complete set should include : Attentions The partition between two antennas, keep distance. Forbidden to open the equipment when the distance between antenna to equipment is less than 5 meters. Otherwise it will not work well. Joint the equipment and antenna tightly, to avoid signal coverage effect is not good. The original machine is equipped with 100V ~ 240V 50HZ three core AC power line, please note that the voltage range of input power. The products work environment: The equipment can work stably for a long time in the following conditions: The temperature is -30 ? ~ +40 ?, humidity below 95%; Dustproof and waterproof: dustproof and waterproof grade: IP65;
