Q How does a cell phone repeater work?

A cell phone repeater is a bi-directional device that catches a mobile signal from the nearest cellular tower and amplifies it to improve the quality of your mobile environment. This has the dual effect of improving your reception and increasing the signal sent from your phone. The major purpose of using a cell phone repeater is to add an extra 2-3 bars to your usual mobile reception. For detailed information, please contact us.
