5watts 850MHz Indoor Signal Booster
5watts coverage 5000m2 GSM850 mobile signal ST850&5W mobile signal booster?A mobile phone signal repeater provides the ultimate solution in any indoor area where cellular communications can not work well due to leak of signals (but outdoor signal good). ?The repeater device features easy installation & operation,Website:, build-in indoor antenna and no interference. ?It could also improve indoor electromagnetism environments, protract cellular battery life and reduce radiation of cellphones. ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ??A mobile phone repeater is ideal for house, home, office use.Best 37dBm 5 Watts GSM 850 MHz Wireless Cell Phone Signal Booster is designed to solve problems of wak mobile signal, which is much cheaper than adding a new base station (BTS).Main operation of the repeaters are to receive lower-power signal from BTS via RF transmission and then transmit the amplified signal to the areas where network coverage is inadequate.And the mobile signal is also amplified and transmitted to the BTS via the opposite directon. ?The repeater makes the signal stronger in places with poor signal coverage such as:1) Underground areas: basements, parking lots, tunnels;2) Other places where cellular signal is shielded by metal or concrete walls: offices, supermarkets, cinemas, hotels;3) Places distant from the BTS like private houses.Specification of Mobile Signal Repeater ST850&5WspecificationsuplinkdownlinkFrequency Range:824-849MHZ869-894MHZMax Gain76dB?183dB?1Ripple in Band?8dBMax.
