They have been designed specifically to amplify a weak signal available outside a house, building or a vehicle, and to broadcast a much stronger signal inside, where it is needed the most.We shall discuss in detail how these devices work, but let us first answer the question, are cell phone signal boosters legit? Yes, they most certainly are and have been approved by the FCC in United States and Industry Canada (IC) in Canada.The FCC has no issue with using cell phone repeaters to extend the range of a cell network in areas that historically receive poor cellular service, including homes and offices, commercial structures and more as long as they are registered with respective service provider before use.Description:Indoor DualBandSignal Repeater (Signal Booster) series is an ideal solution for two wireless system in small/medium businesses and home users looking to enhance indoor wireless connectivity. It is connected via coaxial cable to Donor Antenna and Service Antenna, Donor Antenna is placed outside the building where it has easy access to BTS signal, and the Service Antenna is placed in the building where it can extend radio coverage to the blind area. And Automatic Gain Control (AGC) to avoid the Booster from over saturation, therefore maintaining a high voice quality and avoid adding interference to network. With good looking & super compact design also make it attractive. Besides, it is easy installation feature is also for individual customers to install the booster by themselves, and it does not need much professional knowledge and instrument.The signal boosterimproves mobile signals with no negative impact on human health.Features:Cost effectivesolution for weak signal zones, reduce drop/off calls. Compact size, low power consumption, easy installation, great cover. Expansion and extending of the signal of base station. Optimization of the quality of the signal and sourceCover about1000~5000m² without block or obstruct.High linear design, ALC function design, low interference to BTS.Support any cellular devices (voice & data & video) Wide band signal booster, or customize selective band booster.Advantages:Digital Display Panel,IntelligentmodesettingSmartfunctioncalledwhichcanbeactivatedviathedigital display panel.UserscanchoosegainandworkingsystembyLEDDigitalPanel.Set the technical parameters simple and efficient, this is easierthanDIPSwitch.Standard Package:1)AC90-264V, DC9V/5Apower supply adapter 1PCS2) AC power cord (EU/US/UK/SA/China standard, etc) 1PCS3) Installation kit 1PCS4) User manual 1PCSRecommended Accessories:1)Donor antenna: Log PeriodicAntenna (9dBior 11dBi,806-960/1710-2700MHz)2)Service antenna: Omni Ceiling Antenna (3dBi,806-960/1710-2700MHz)3)5D-FB coaxial cable with connectors(Cable length optional)Application:To expand signal coverage or fill signal blind area where signal is weak or unavailable.Indoor: Hotels, Home, basements, Shopping Malls, Offices, Parking Lots, Shop.etc.Specification:Frequency RangeUplinkDownlinkDCS 1800MHz + WCDMA 2100MHz(Band5 + Band 10)824-849/1710-1755MHz869-894/2110-2155MHzMax.

A typical signal booster is based on a three-part system.It consists of an outside antenna that captures the weak cell signal, an amplifier that boosts the signal thus received, and an inside antenna that rebroadcasts the much enhanced signal within the room, house, building or vehicle.An outside antenna is mounted in a location outside the house or building which currently gets a signal, usually on the roof. This signal is then passed from outside antenna to a signal amplifier within the building. An amplifier enhances the signal by up to 32X times and then sends it to the inside antenna. An inside antenna rebroadcasts the signal to the area where it is needed the most.That is how you get a much improved signal from the cellular tower. The same process works in the reverse. The signal from your phone is picked up by inside antenna, enhanced by amplifier and sent out to the outside antenna, which rebroadcasts it so that a much stronger signal is received by the cellular tower. This establishes a strong two-way communication between your phone and the cellular tower.Amplifier.An amplifier or a cellular repeater receives the signal from the outside antenna and boosts it by 32X times. Amplifiers are measured in terms of dB (decibel) output. Amplifiers used in home-based systems offer anything from 500 to 20,000 sq. ft. of coverage.Most exterior cell phone signal strength ranges from -50 dB to -120 dB. In terms of bars, -50 dB means full bars and -120 dB means zero bars or a dead zone. Amplifiers boost the cell phone signal so as to get the reading closer to -50 dB.You should get a +60 dB gain at least with an amplifier. The best and most powerful amplifiers give you a +70 dB gain. Amplifiers that have been specifically designed for vehicles should give a +25 dB gain at least, with a maximum of +50 dB gain.If you are able to get a consistent -94dB or better signal outside, then signal amplifier will be able to multiply signal to boost reception indoors substantially. However, the typical cut off point for signal boosters to be able to amplify is -105dB outside signal. If exterior signal is less than that amount, say for example, -115dB, then signal amplifier will not be able to help in such a situation.What frequency repeater do I need?Most mobile carriers broadcast their networks on either of the 900 or 1800 Mhz frequency bands, or both. High-speed data networks or 3G service is broadcast on the 2100MHz band. Newer 4G LTE networks are often shared on 1800 MHz or on 800 / 2600 MHz frequencies. Your repeater should match the same frequency as your mobile carrier in order to ensure compatibility. To determine which type of repeater you need, you can visit our support center or mobile booster kit guide, which will recommend the best model to suit your needs.Can I install a repeater unit myself?Absolutely. There is no technical expertise required to install your mobile repeater kit. Each kit contains everything needed to improve the mobile coverage in your home/office and includes instructions that will guide you through the simple steps necessary to install your repeater.How will my repeater be delivered?All orders are shipped via DHL express and are normally delivered within 1-4 business days.
