4G,3G,2G All Networks Signal Booster

A mobile phone signal repeater provides the ultimate solution in any area where cellular communications can not work well due to lack of network /signals.  The repeater device features easy installation & operation, 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.our  cell phone signal boosters work with all cellular telephone technologies and networks used in North American USA & Canada, The only exception is that of Push-to-Talk (PTT) networks which is one wireless telecom service platform that is being phased out already. Basically all our signal boosters are GSM signal boosters because they cover 698 MHz to 1755 MHz frequencies and bands that encompass the GSM network being used by several mobile service carriers in Canada and United States. Furthermore, those frequencies also cover other wireless networks including CDMA, WCDMA, EDGE, HSPA+ and EVDO.

Important Note ( please read , and please read all descriptions carefully ) Make sure you can receive good signal that you want to amplify on your house outside, which must be can getting 3~5 bar signal (-70dB~-90dB signal strength) on your mobile phone. Please note that the signal booster can only boost the mobile phone network signal, but does not help to generate any signal. For example, if your outside signal has 0 bar, it can not work or bring you any signal... Below is the method to check the mobile phone signal strength. Specification: 1. Gain: 70dB (DL); 65dB (UL) 2. power output: 20dBm 3. GSM: up to link 890-915 mhz; down link 935-960 mhz DCS: up to 1710-1785 mhz; down link 1805-1880 mhz WCDMA: up to 1920-1980 mhz link; down link 2110-2170 mhz 4. impedance: . 5. Connector Type: N Female Connector Packaging: 1.Signal Booster 2.outd
