How a cell phone signal booster works: A cell phone signal booster uses an outdoor antenna to search for cell phone signals in the area. It captures those signals and boosts their power with a signal booster. An indoor antenna broadcasts the strengthened signal so that your phone can receive it.

1. The indoor and outdoor antenna is best to keep the distance of more than 8m(26ft), preferably separated by walls. The outdoor antenna is preferably installed horizontally in a better signal area and faces a cell tower.
2. Need 2 to 3 bars signal outside, otherwise the signal can not be amplified, because this is a cell phone signal repeater. A booster can only enhance the signal, can’t create a signal.
3. In order to boost your 4G LTE signal, please confirm that the 4G LTE band of your cell phone card in your area is 2 or 13. If you don’t know your band, you can query through these simple operations(iPhone: Dial *3001#12345#* -> Serving Cell Info -> LTE -> Freq Band Indicator, Android Phone: Download and install the app ‘LTE discovery’ -> SIGNALS -> EARFCN).
