Cellphone Signal Booster is also called cellphone signal amplifier/ repeater, or mobile signal booster/amplifier/repeater, and the Mini cellphone signal booster tri-band which can works for GSM900MHz&DCS1800MHz&4G world-wild GSM900,1800 and 4G system.
Cell phone signal booster is a products designed to solve the mobile phone blind signal. In some places such as tall buildings, underground rooms, countryside, your cell phone can not receive the signal well. Then, a repeater/booster/amplifier can help you. Mobile phone signal repeaters/boosters/amplifiers are able to pick up weak cellular signal from a BTS and transmit them to your mobile phone, and then transmit a more powerful signal back to the BTS. Mobile phone signal repeaters overcome the problem of dropped calls, limited range and slow data rates.
