Wilson Electronics PRO series is a line of commercial cell phone signal boosters that boost 2g, 3G, and 4G LTE cell signal in a multi-story 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. The majority of poor signal inside a commercial building is usually building material and not distance from the cell tower. This is especially true of the city and other areas with urban development. Many legacy buildings are built with high-density materials such as thick concrete, brick, and metal which blocks cell signals. Many modern buildings use energy-efficient materials such as radiant barrier and low-energy glass which also disrupts cell signals. Any combination of these obstructions will interrupt cell signal from getting inside the building. This is why a commercial cell phone signal booster from Wilson Electronics is important for getting more bars instantly for many enterprises. It takes any signal, enhances it, and bypasses all building obstructions to deliver consistent signal strength.
