Why we should buy mobile signal repeater/ signal booster/ 3G amplifier :

Cell phone becomes especially helpful when people get into critical situations. In case of emergency a timely call can save somebody’s life.

How is mobile phone signal repeater GSM/DCS/ 2G/3G/4G WORKING ?

•The outside antenna catches the low signal from the mobile base station and delivers it to the cell phone

amplifier through the connection cable (coax).

•After the signal is accepted by the phone amplifier, the device amplifies it.

•Then this amplified signal goes through the connection cable (coax) to the inside antenna.

•And after that, the amplified signal transmits to the cell phone.
