High power CDMA850MHz signal repeater in boosters

 

 

Cell phone signal amplifier (alias signal booster,  civil small repeater) is specifically designed to solve cell phone signal blind products. As the phone is transmitted by electromagnetic waves to establish a communications link, the building of the barrier, in some tall buildings inside the basement of some places such as malls, restaurants, places of entertainment such as karaoke OK sauna and massage, underground civil air defense projects, subway stations many places, cell phone signals can not reach and can not use the phone. Cell phone signal amplifier can solve these problems, the signal coverage: outdoor open area of 1000 square meters, covering an area of 500 square meters indoor.
