How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.
Formula
Interpret RSSI with SNRInputs
| Name | Unit |
|---|---|
| RSSI | dBm |
| SNR | dB |
Outputs
| Name | Unit |
|---|---|
| RSSI (hero result) | dBm |
| SNR | dB |
Diagnose
Observations are context. They do not pass or fail a structure. See Diagnose.
| When | Observation | Severity |
|---|---|---|
strong and poor snr | Strong signal, poor SNR | info |
weak and poor snr | Weak signal, poor SNR | info |
weak and good snr | Weak signal, good SNR | info |
Otherwise | Signal context | info |
Assumptions
- Manual or captured measurements. Thresholds are illustrative context only.
Provenance
- Generic RF context. Do not treat bands as LoRa, LTE, or Wi-Fi criteria.
