Introduction
Congratulations on purchasing the SureCall Fusion-5, the finest cellular signal
booster available!
SureCall adjustable cellular signal boosters and kits from Cellphone-Mate remove
frustrations over dropped calls, limited range, and slow data rates by amplifying incoming
and outgoing cellular signals in buildings, offices, and homes. The Fusion-5 is designed
with leading-edge technologies to detect and amplify weak incoming signals your cellular
device would otherwise miss and to broadcast a significantly stronger signal back to the
cell tower.
This guide contains all the information you need to get your SureCall Fusion-5 booster
system up and running.
Theory of Operation
The SureCall Fusion-5 is a high-quality bidirectional signal booster that boosts cellular
signals for areas prone to weak or shadowed cellular coverage.
The Fusion-5 works with two antennas
:
xAn inside antenna that communicates with your cell phone.
xAn outside antenna that communicates with the cell tower.
Signals sent from a cell tower are received by the outside antenna, amplified 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 Fusion-5 to enhance cellular signal coverage. The
weakest cell signal for the Fusion-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 strength to find a cell signal measurement app.
