1.4 - How It Works

The Force-5 amplifier boosts cellular signals from
W
the nearest tower to phones in a building and
from those phones back to the tower to compen-
sate for weak r
topography, building structure, and/or other rea-
sons. The amplifier receives the signal from an
outside antenna, amplifies that signal, and then
rebroadcasts it via the interior antenna(s) where it
is picked up by cellular phones, modems, and data
cards. The interior antennas also pick up signals
from cellular devices and pass them to the ampli-
fier. The amplifier boosts these signals and passes
them to the exterior antenna for rebroadcast back
to the tower.
