Understanding Mobile Signal Boosters

Mobile phone signal boosters are tools that amplify the reception of mobile phones. The devices function by picking up weak signals from the closest cell tower and boosting them so they may be rebroadcast to an area with poor service. A typical signal booster will include an exterior antenna, an amplifier, and a second, smaller antenna on the inside.

The external antenna receives the weak cell signal and feeds it to the amplifier, which strengthens the signal. The boosted signal is then relayed by the internal antenna to the area where the booster has been set up. The kind and size of mobile signal boosters you need will depend on the area that you need to cover and the quality of the existing signal.
