2watts coverage 3000m2 GSM mobile signal ST850&2W mobile signal booster What is the booster?Cell phone signal booster (also named repeater,Website:http://www.mobilesignalboosterchinas.com, amplifier) is a product designed to solve the mobile phone blind signal. As the mobile phone signal is transmitted by electromagnetic waves to establish a communications link, however there are a lot barriers make it is unavailable to get sound signal. When people enter some tall buildings, some places basement malls, restaurants and parking lot, some places of entertainment such as karaoke sauna and massage, some public place such as subway, tunnel and etc. where cell phone signals can not reach, now the cell phone signal booster can solve these problems! The entire range of mobile phone signals can be well used; we all will get great convenience and benefit from sound signal.Our boosters are the perfect solutions for a wireless improvement in the mobile reception!Range of application:1.High-density and low-layer houses.2.Suburb areas which are far away from the base stations.3.Closed space like basement or elevator shaft.4.Large indoor houses like villa or factories.Reasons to Purchase Cell Phone Repeater.Mobile Phone Signal Repeater 1.Enhance Mobile Phone  Signal Strength2.Improve Communication  Quality3.Reduce Cellphone  Radiation4.Protract  Cellular Battery Life5.Economic Building Cost6.Easy Operation7.Easy Installation8.Build-in Power SupplySteps that describe the work of Repeater.1)The outside antenna receives the signal from the nearest mobile base station.2)The outside antenna sends the received signal through the coax cable to the installed Repeater.3)The repeater accepts the low signal and improves it.4)The improved signal goes to the inside antenna through the connection coax cable.5The inside antenna send the improved good signal to your mobile phone.        Specification of Mobile Signal Repeater ST850&2WspecificationsuplinkdownlinkFrequency Range:824-849MHZ869-894MHZMax Gain76dB±183dB±1Ripple in Band≦8dBMax.

Please ensure the outdoor and indoor antenna have distance of 20 meters at least, with a wall between and not at the same horizontal line(outdoor antenna can be one floor higher than the repeater and indoor antenna).4.Indoor antenna and repeater better to be minimum 4 meters far away from nearby windows and doors. Note: To use this product to enlarge your signal, the outdoor signal shall be as good as possible. The product will not work well if our outdoor signal is not good or bad.In case the indoor signal is always very low while outdoor signal is very good, the repeater can work well. If the indoor signal is sometimes full sometimes not at all before installing,  this environment is not suitable to install the repeater.Choose the suitable Repeater If your best outside signal is full bar or strongest, you can choose your suitable repeater to install your home and office. Higher output power, more coverage area. Higher outside gain,  better inside signal. Less inside Antenna, stronger inside signal. If your outside signal is lower, you can choose higher gain repeater.Output PowerGainSupport ANT NumberTheory Coverage(Open)Factual Coverage14dBm55dB1300sqm.100sqm.17dBm60dB1-2600sqm.200sqm.20dBm70dB1-31000sqm.300sqm.23dBm70dB1-41200sqm.400sqm.25dBm75dB1-61500sqm.500sqm.27dBm75dB1-82000sqm.1000sqm.30dBm80dB1-103000sqm.1500sqm.33dBm85dB1-155000sqm.2500sqm.40dBm95dB1-30---5km43dBm95dB1-50---10km46dBm95dB1-80---20km
