What is a “Cell Signal Booster”?

A cell signal booster is a device that receives cell signals from a carrier tower using an antenna then amplifies it and rebroadcasts it though one or more antennas. The purpose is to bring usable cell signal into areas with weak unusable cellular reception. Various types of cell signal boosters have been around for years in the consumer market and even longer in the commercial world.
