Products instruction

Cell phone signal amplifier is a products designed to solve the mobile phone blind signal. As the mobile phone signal 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, sauna and massage, underground civil air defense projects, subway stations and many other places where cell phone signals can not reach and can not use the phone. Cell phone signal amplifier can solve these problems in a particular place as long as the installation of a mobile phone signal amplifier system, the entire range of mobile phone signals can be well used, and all the staff or customers will get great convenience.
