Signal strength indicators on the Mobile status page
On routers equipped with W-WAN modules, there are three LEDs on the front panel that indicate the
strength of the signal, as shown in the following table. The web interface also displays signal
strength in the Signal Strength field on the Management > Network Status > Mobile page:
The signal strength is shown in negative dB, which means that the stronger the signal, the lower the
number. As a guide, -51 dBm is a very strong signal, normally only obtained very close to a cell site. -
115 dBm represents no signal. If your router reports -115dBm, try reorienting the antenna or
consider adding an external antenna.
The following values are fairly specific to LTE. At 2G/3G technology, any strength lower than -100
dBm becomes unusable.
LEDs lit Signal Strength
None No Signal: under -113 dBm
1 Weak signal: -112 dBm to -87 dBm
2 Good signal: -86 dBm to -71 dBm
3 Excellent signal: -70 dBm to -51 dBm
