Step 3:
Measure Signal
Strength For Inside
Antenna Placement
Having an accurate measurement of signal strength in decibels (dBm) is crucial
when installing your system. Decibels accurately measure the signal strength you
are receiving. Test both 3G and 4G signal for best results by turning the LTE off in
the carrier settings of your device.
SIGNAL STRENGTH
EXCELLENT
GOOD
FAIR
POOR
DEAD ZONE
3G/1x
(typically voice)
-70dBm
-71 to -85dBm
-86 to -100dBm
-101 to -109dBm
-110dBm
4G/LTE
(typically data)
-90dBm
-91 to -105dBm
-106 to -110dBm
-111 to -119dBm
-120dBm
Turn off your cell phone’s
WiFi to ensure you
are checking the cellular connection.
The dBm
reading will be refreshed every 30-60 seconds.
Want faster results? Once you have a reading,
turn on
airplane mode.
Wait 15 seconds.
Turn off airplane mode. The signal strength
reading is refreshed.
Walk around your home/office taking signal
strength readings until you find the area that has
the weakest reception, or number farthest away
from zero. For example -100 is a weaker signal
than -80.
Users on iOS 11 and above will need to use an
alternative method using the bar indicator on
your cell phone and/or placing calls in different
locations.
Weakest Signal Number:___________
Weakest Signal Location: ___________
Place your Inside Antenna in this poor signal area.
For best results, keep the inside antenna more
than 18 inches away from the booster.
