SureCall Fusion2Go - How It Works

3
The SureCall Fusion2Go is a high-quality bidirectional booster that enhances cellular
signals for cars, motor homes, and other vehicles.
The Fusion2Go works with two antennas:
• An inside antenna that communicates with your cell phone.
• An outside antenna that communicates with the cell tower.
Signals sent from a cell tower are received by the outside antenna, amplied by the
booster and then sent to your cell 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. A minimum amount of cellular reception is required for the
Fusion2Go to work properly. Cellular signal strength is measured in dBm, an
abbreviation of the radio power per milliwatt. A minimum of -100 dBm is required.
Signal readings usually appear as a negative number (for example, -85). The stronger
the signal, the closer it gets to zero. See graph below.
