The Wilson Pro 70 Plus Select features +70 dB gain and maxed download power along with Wilson Electronics patented signal boost technology. This results in 32X amplified signal, 30X coverage area, and 2X the number of simultaneous users when compared to other boosters. 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.
