1.4 - How It Works
The CM2500W amplifier boosts cellular signals
from the nearest cellular tower to phones in a
building and from those phones back to the tower
to compensate for weak reception caused by dis-
tance, topography, building structure, and/or
other reasons. 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 amplifier. The amplifier
boosts these signals and passes them to the exte-
rior antenna for rebroadcast back to the tower.
