17dBm 900MHz Signal Booster Vehicle Use AGC ALC
GSM signal Booster for GSM mobile signal ST900&AI mobile signal booster for car/Vehicle/Home Use Max coverage 300sqmWhat is Mobile Phone Repeater?A mobile repeater picks up mobile signals from the outdoor antenna,Website:, then process and amplified the signal and rebroadcast to indoor areas by the indoor antenna. Mobile repeater is designed to increase mobile signal strength to all mobile s on all mobile carriers and providers. Mobile repeater could virtually eliminate dropped calls, stuck text messages and slow internet speed. Mobile repeater system is the one-time investment without extra fees or landline internet connection.What is AI intelligent Repeater ?All Intelligence repeater with Smart CPU software and ATT function : What is AI function? And what is the advantage?AI means Artificial IntelligenceThe booster is with CPU inside, it can control the gain more intelligence according to surroundings than AGC function.The booster with AI is energy-effective. When there is no call, the booster will change to a “Stand-By” state, thus can save a lot power.The boosters with AI function have ALA LED on it, and it can easily help to find out the problem when setting and running.Smart CPU software have three function :1.it can help you save power ,when there is no mobile using ,the repeater will auto-turn down the uplink signal ,help you save power ;2.it can help you check out when your installation have problem , when your installation is wrong , the repeater can check out and the ARL LED will be lighted and alarm .3.it can pretect repeater when there is a thunder or there is a very stronger repeater come in suddenly , the repeater ARL will alarm and remind you to re-plug the repeater adaptor;Features of ST Signal Repeater :1.High-gain linear power amplifier. 2.ALC and AGC function technology. 3.Ultra-low noise receive amplifier. 4.There is no interference to the base station, right after the opening of the original system and the base station without the need to adjust parameters. 5.Stable and reliable electromagnetic compatibility design. 6.The base station dose not cause an increase in background noise, but will not lead to a decline in the quality of the base station communications. 7.With full-duplex communication mode. 8.It explores an effective and reasonable method to dispel the heat.ST900&AI Intelligent mobile signal booster specificationFrequency rangeuplink:890-915MHzDownlink: 935~960MHzGainUp link: Gp≥63dBDownlink: Gp≥68dBoutputUp link :15dBm Downlink: 17dBmFunctiona) Power supply LED denoteb) Export power LED denotePort VSWR≤1.8DBI/O impedence50Ω/N connectorNoise figure≤6dBTransmission delay≤0.5μsAmbient temperature-15°C~55°CPower supplyAC/220V±10% 45~55HzSize/weight124*112*12.5MM/600gCoverage area300sqmMobile Phone signal Booster Installation complete kit items1 x 65dB Repeater1 x 8dBi Gain Outdoor Yagi Antenna1 x 3dBi Gain Indoor Ceiling Antenna1 x 5 Meters Low-loss Coaxial Cable for connecting indoor Antenna1 x 15 Meters Low-loss Coaxial Cable for connecting outdoor Antenna1 x AC Adapter4 x Screws for Mounting Signal BoosterMobile Phone Signal Repeater Installation StepsStep 1: Install the outdoor antenna in a suitable placeStep 2: Connect the outdoor antenna to the booster “outdoor” side by cable and connectorStep 3: Connect the indoor antenna to the booster “indoor” side by cable and connectorStep 4: Connect to the powerNotices:1.Connect outdoor (BTS) port with outdoor antenna. Connect indoor ANT (MS) port with indoor antenna. Outdoor antenna is mounted at a higher position. Both antennas should be 10 meters far away at least from each other. 2.Indoor and outdoor antennas must be separated by wall. 3.If the signal is still weak after installation, please check whether or not the outdoor antenna is pointed to signal tower correctly or elsewhere with stronger signal and confirm that the signal strength achieved -70dBm. 4.If no signal for a long time after installation, please check the device power adapter whether or not connected perfectly and connectors connect well. 5.If strength is not steady, please check if outdoor and indoor antennas are too close. Please ensure outdoor antenna has distance of 10 meters at least, with a barrier and not in a same horizontal line. 6.Packed the outdoor connector by waterproof glue, otherwise wet condition will reduce the signal cover area.LED IndicatesLEDStatusDefinitionPowerRedNormalOffDC power problemDL(Downlink)WhiteNo signal receivedSolution: Adjust the outdoor installation to get sound signal(see page 14)GreenSignal received ok but not perfectSolution: Adjust the outdoor installation to get sound signal(see page 14)RedFull signal receivedUP(Uplink))FlickerWhen there is a call, it is normalGreenAlways green means self-excitedSolution: Turn off the booster, adjust the indoor and outdoor antenna again, and try to expand the distance or create some barriers between them.Terms and ConditionsCertificateCE/RoHsCountry of OriginChinaPort of DispatchShenzhenProduction Capacity1000pcs/monthDate of DeliveryWithin 3 days after received payment informMOQ10pcsWarranty2yearsPacakge1pcs/box; 20pcs/cartonCountry of OriginChina
