How do Hiboost Signal Boosters work?

A cell phone signal booster works by captures the existing outside signal with its exterior antenna. The outdoor antenna transmits the signal to the cellular booster. . The booster then amplifies the signal and rebroadcasts it through the interior antenna. Correct installation of these components is essential before you enjoy boosted signal for better call quality and faster data speed.

The major reason why you have weak signal reception includes distance from your house to the nearest cell tower and the construction materials around that block cell signal from pulling in.
