Also called signal boosters, signal extenders, signal amplifiers, repeaters work by pulling in weak outside signal and boosting it to improve call quality, weak cell signal, as well as provide faster data speeds.
If you have usable signal outside your home, vehicle, or office building, but weak to no signal inside, then a repeater will definitely improve your cell service and signal strength. You will eliminate dropped phone calls, slow data speeds, and unsent text messages without needing to connect to WiFi, complain to your carrier, or switch carriers.
There are different boosters available that cater for different needs:
Signal repeaters are composed of three main elements:
An external antenna – Used to capture the weak cell phone signal
An amplifier – Used to boost the weak signal
An indoor antenna – Used to rebroadcast the enhances signal inside your home, office, or car.
Please note – For a signal repeater to work, there must be an existing signal outside your home, office, or vehicle. A cell signal booster enhances existing signal; it does not create it.
