HPC-G27 GSM900mhz Mobile Phone signal boosterGSM mobile networks are everywhere around the world but depending on where a mobile phone is located,Website:http://www.mobilesignalboosterchina.com, regrettably the quality of the GSM signals differ significantly from excellent to poor. The item in auction is designed to address the signals strength issue by boosting the signals in two directions (Full Duplex) :1.signals transmitted from a mobile phone are received by the signal booster over the air via the booster's indoor antenna and these signals are amplified and retransmitted over the air via the booster's outdoor antenna to a nearby cellular phone base station.2.signals transmitted from a cellular phone base station are received over the air by the booster via the booster's outdoor antenna and these signals are amplified and retransmitted over the air via the booster's indoor antenna to a mobile phone.The GSM Booster can be viewed as an intermediate agent to help to set up a reliable wireless link between a mobile phone and the GSM mobile networks infrastructure.Applications:The Booster is particularly useful in zones with poor GSM coverage such as basements, car parks and tunnels. It can also be used in offices, homes, supermarkets, cinemas and hotels etc.It is specifically designed for indoor uses. The Booster employed advanced filtering technology to reject the out of bands signals in the amplification stages, this results in crystal clear voice communication for an established GSM call as the GSM uplink and downlink signals are effectively isolated . Its AGC (Automatic Gain Control) mechanism ensures an optimum power is provided for the cell phone site as well as the mobile phone; all these are performed without user's intervention.How the Booster benefits youReduce dro calls and improve GSM voice communication quality.We provides signal boosters kits for any Homes, Offices, Cars, RV's, Boats and more. All amplifier kits come with Indoor and Outdoor Antennas, Cables, Power adapters and more.HPC-G-27 GSM900mhz repeater Features:1.With unique appearance design, have good cooling function2.With MGC function,(Manual Gain Control), Customer can adjust the Gain as needed ;3.With DL signal LED display, help to install the outdoor antenna at the best state; 4.With AGC and ALC, make repeater work stable . 5.PCB with isolation function ,make UL and DL signal not influence each other,6.Low intermodulation, high Gain ,stable Output power HPC-G-27 900mhz repeater Inside and Outside DesignTechnical Features Receiving and sending separation,low require for Ant isolation,making it convenient for installation.Mini design with metal cavity filter technology inside.Full-duplex&dual-port design,and built-in power supply,making it convenient for installation.ALC technology used to provide auto amplitude fixing.Modules structures,making it convenient for installation,debugging and maintenance.Specification of HPC-G-27 Dual band repeater:Electrical specificationUplinkDownlinkFrequency RangeGSM900890 ~ 915 MHz935 ~ 960 MHzMax .Gain≥ 70dB≥ 75dBMax .Output Power≥ 24dBm≥ 27dBmMGC ( Step Attenuation )≥ 31dB / 1dB stepAutomatic Level Control≥ 20dBGain FlatnessGSM & CDMATpy≤ 6dB(P-P); DCS,PCS ≤ 8dB(P-P)WCDMA≤ 2dB/ 3.84MHz,Full Band ≤ 5dB(P-P)Noise Figure≤ 5dBVSWR≤ 2.0Group Delay≤ 1.5μsFrequency stability≤ 0.01ppmSpurious Emission & Output inter-modulationGSM Meet ETSI TS 151 026 V 6.1.0WCDMA Meet 3GPP TS 25.143 ( V 6.2.0 )CDMA Meet IS95 & CDMA2000WCDMA SystemSpurious Emission MaskMeet 3GPP TS 25.143 ( V 6.2.0 )Modulation Accuracy≤ 12.5%Peak Code Domain Error≤ -35dB@Spreading Factor 256CDMA SystemRhoρ > 0.980ACPRMeet IS95 & CDMA2000Mechanical SpecificationsStandardI /O PortN-FemaleImpedance50 ohmOperating Temperature-25ºC~+55ºCEnvironment ConditionsIP40Dimensions155x112x85mmWeight≤ 1.50KgPower SupplyInput AC90-264V,output DC 5V / 3ALED AlarmStandardPower LEDPower IndicatorUL LEDBe lighted when there is phone callingDL 1Be lighted when Outdoor signal is -65dBDL 2Be lighted when Outdoor signal only -55dBDL 3Be lighted when Outdoor signal only -50dBThe installtion of the RepeaterOutdoor antenna ( for receiving the signal from the BTS ) + Cable ( transfering the received signal) + Repeater ( for amplifying the received signal) + cable( for transfering the amplified signal) + indoor antenna( for shooting the amplified signal), (Note : Omni indoor antenna is 3dBi,it can work with about 200m2 . If need repeater coverage larger area , need add more antenna,the HPC-G-27 Max can work with 10pcs indoor antenna. ( when add antenna ,please remember to take splitters )Installation Approaches:Fix up outdoor antenna reception on housetop and point to signal towerConnect outdoor antenna to 'outdoor' port in repeater machine through cableConnect indoor antenna(s) to 'indoor' port in repeater machine through cable alsoPlug power adaptor into AC power socket and finish installationTechnique Supporting:If still no signal receipt after activated repeater, please check if outdoor antenna point tosignal tower or elsewhere have strong signal and check if strength achieve -70DBM.If strength is not steady, please check if outdoor and indoor antenna are too close.Please ensure the outdoor and indoor antenna have distance of 20 meters at least ,with a wall between and net a same horizontal linePicture show:Terms and ConditionsCertificateCE/RoHsCountry of OriginChinaPort of DispatchShenzhenProduction Capacity1000pcs/monthDate of DeliveryWithin 3 days after received payment informMOQ10pcsWarranty2yearsPacakge1pcs/box; 20pcs/cartonCountry of OriginChina
