## LoRaWAN Network Test

![ping](/img/lorawan/ping.svg)

When you press **Send Uplink**, the device performs:

- A **server connectivity check**
- A **basic RF analysis**
- Sends a **confirmed uplink** (expects acknowledgment from the server)

## Uplink Status

✅  **Successful Uplink** – Device received acknowledgment from the server  
❌  **Failed Uplink** – No acknowledgment received

## Spreading Factor (SF)

Defines the trade-off between range and data rate.  
**Valid range:** `SF7` (short range, fast) to `SF12` (long range, slow)

## SNR – Signal-to-Noise Ratio

Measures signal clarity.

- **Good:** `0 to +10 dB`  
- **Acceptable:** `-10 to 0 dB`  
- **Poor:** `-20 to -10 dB`

> **Note:** Higher SNR = cleaner signal

## RSSI – Received Signal Strength Indicator

Measures signal power in dBm (always negative):

- **Excellent:** `-30 to -50 dBm`  
- **Good:** `-51 to -90 dBm`  
- **Weak:** `-91 to -120 dBm`  
- **Very Weak:** `< -120 dBm`

> **Note:** Closer to 0 = stronger signal
