Wilson Electronics PRO series is a line of commercial cell phone signal boosters that boost 2g, 3G, and 4G LTE cell signal in a multistory building or office. The Wilson Pro 70 takes the existing cellular outside signal and amplifies it up to 32X with Wilson Electronics’ patented signal boost technology. With up to +70 dB gain of power, the amplified signal is rebroadcasted inside the building for much improved cellular service.
