B-25K

American Booster B-25K has been designed to improve and extend cellular coverage inside

®

the buildings. B-25K amplies signals from the nearest base station and re-transmits them at higher
power level. B-25K provides service at 700MHz LTE, 850MHz Cellular, 1900MHz PCS and 2100MHz AWS
frequencies without any additional setup or conguration.

How it works

Receives Signal

The signal booster’s outside

antenna receives voice and

data signals from a nearby

cell tower.

Receives Signal

The signal booster receives
the signal from the outside

antenna and after amplifying

the voice and data signals, sends

them to the inside antenna.

Improves Signal

The inside antenna

distributes the boosted

signals inside your building.
