Cell phone signal boosters are also interchangeably called "cellular repeaters," "cell signal amplifiers," and sometimes "network extenders."

Boosters help the most when you have a weak signal, not when there's none at all. Whereas your phone shows bars, wireless industry folks measure signal in -dBm. A number higher than about -90dBm (like -80 or -70) is a strong signal. Anything below -110dBm is definitely weak, and you might not hold onto any signal below -120dBm.
