Theory of Operation
The SureCall Force-5 is a high-quality bidirectional signal booster that boosts cellular
signals for areas prone to weak or shadowed cellular coverage.
The Force-5 works with two antennas
:
x An inside antenna that communicates with your cell phone.
x An outside antenna that communicates with the cell tower.
Signals sent from a cell tower are received by the outside antenna, amplif ied by the
booster and then sent to your phone via the inside antenna.
When your phone transmits, the signal is sent to the inside antenna, and then sent to
the cell tower via the outside antenna.
Some cell signal is required for the Force-5 to enhance cellular signal coverage. The
weakest cell signal for the Force-5 to work is low -100dBm to high -90dBm. dBm is an
abbreviation for the power ratio in decibels of the radio power per one milliwatt.
To measure your existing cell signal on an Apple iPhone, dial *3001#12345#*and
press Call. In the top-left corner, a number appears instead of bars.
For Android devices, you can download several apps to measure exact signal
strength. Look up check real signal st ren gth to f ind a cell signa l meas urem ent app.
