Troubleshooting &
Understanding Lights
The lights on the front of the Mobile 4G
Signal Booster indicate whether the
system is working or if there are problems.
Each light indicates the operation of its
labeled frequency. Take the following steps
based on the indicator light color when
using the Mobile 4G Signal Booster.
Lights off: If the lights are not on:
• Check connections on the power supply
to see that it is firmly plugged into both
the Mobile 4G Signal Booster and the
power source.
• If using a DC power supply in your
vehicle, ensure the power supply is
properly inserted. Then check the 12
volt power from the car socket and the
fuse. Replace the fuse if necessary.
Red light: A red light indicates oscillation
is occurring. Oscillation is similar to
feedback between a microphone and
speaker. When oscillation occurs, the
Signal Booster will power down to protect
the cell tower. To eliminate oscillation, the
outside antenna needs to be moved farther
from the inside antenna. Move the outside
antenna on the roof to the rear of the car,
but at least 8 to 12 inches from the rear or
side windows. Disconnect the power from
the Signal Booster, then reconnect the
power to reset the Signal Booster.

Flashing red light: If one or more of the
lights on the Signal Booster are blinking
red, this means that the Signal Booster
has shutoff due to close proximity to the
handset or mobile device. Increase the
distance between the handset and the
Inside Antenna until the light is no longer
flashing red. Contact Wilson Electronics
Technical Support Team for assistance.
Green light: A green light indicates the
Mobile 4G Signal Booster is working
properly.

Booster, please contact the Wilson

How does weather affect the
performance of my outside antenna?
Water vapor (e.g. rain, fog, snow or
other precipitation) creates an effective
filter to cellular signal. In times of
heavy precipitation, you may see less
performance.
What's the difference between the 800
MHz and the 1900 MHz bands? How do
I know which MHz band my cell phone
uses?
The Mobile 4G works with all major North
American cellular providers on the 800
& 1900 MHz frequencies. Traditionally,
800/1900MHz are associated with
voice and 3G data; while 700MHz
and 1700/2100MHz are associated
with 4G data. For more detail, refer to
