Device status LEDs

Once power has been established, your device will initialize and attempt to connect to the network. Device initialization may take 30-60 seconds. By default your EX15 will attempt to use DHCP to establish an Internet connection either through its cellular modem or the ethernet port .

  1. Cellular connectivity status is indicated by the color-coded LTE light.
  2. Indicator lights on the Wireless Strength Indicator show you the cellular network signal strength.
  3. Ethernet connections are confirmed via the light corresponding to the EX15 port number.

Signal quality indicators

Signal bars Weighted dBm Signal strength % Quality
-113 to -99 0% to 23% Bad
-98 to -87 24% to 42%

Marginal

-86 to -76 43% to 61% OK
-75 to -64 62% to 80% Good
-63 to -51 81% to 100% Excellent

The weighted dBm measurements are negative numbers, meaning values closer to zero denote a larger number. For example, a -85 is a better signal than -90.

Note See Cellular signal quality explained for more information regarding how signal strength is calculated and subsequently displayed via the LED indicators.
