Signal quality indicators
LED 1 to 5 indicate the cellular service quality level.
| 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 |
Note:
The weighted dBm measurements are negative numbers, meaning values closer to zero denote a larger number. For example, -85 dBm is a better signal quality than -90 dBm.
Ethernet Link and Activity
The ETH port’s LEDs indicate both network interface activity and interface uptime.
