Signal
Information about the modem's signal to nearby cellular towers.
- Signal LEDs - Control the device's signal LEDs.
Properties
Signal level
The signal level is a simplified indication of the quality of the cellular signal.
The thresholds used to calculate the signal strength are provided in the following two tables.
LTE/4G Level
The LTE level as determined as the lesser level of RSRP and SNR levels, and in the absense of RSRP or SNR, the RSSI level is used.
| Level/Bars | RSRP | SNR | RSSI |
|---|---|---|---|
| 5 | >= -90dB | >=10 | >= -75 |
| 4 | >= -100 | >= 5 | >= -85 |
| 3 | >= -110 | >= 1 | >= -95 |
| 2 | >= -120 | >= -5 | >= -105 |
| 1 | connected | ||
| 0 | no service |
3G Level
The 3G Level is a simple RSSI calculation.
| Level/Bars | RSSI |
|---|---|
| 5 | >= -80 |
| 3 | >= -90 |
| 3 | >= -100 |
| 2 | >= -110 |
| 1 | connected |
| 0 | no service |
