What is LoRaWAN
LoRaWAN (Long Range Wide Area Network) is a low-power, wide-area networking protocol designed for wireless, battery-operated devices in regional, national, or global networks.
Key Features
Long Range
- Coverage up to 10-15 km in rural areas
- 2-5 km in urban environments
- Penetrates buildings and underground locations
Low Power
- Battery life of 5-10+ years
- Optimized for infrequent, small data transmissions
- Sleep mode between transmissions
Low Cost
- Simple, inexpensive sensors
- No SIM cards or monthly cellular fees
- Minimal infrastructure requirements
How It Works
LoRaWAN uses a star-of-stars topology:
- End Devices (sensors) transmit data
- Gateways receive signals from multiple devices
- Network Server manages the network
- Application Server processes the data
End Device → Gateway → Network Server → Application Server → Your AppFrequency Bands
LoRaWAN operates on unlicensed radio spectrum:
- EU868: 863-870 MHz (Europe)
- US915: 902-928 MHz (North America)
- AS923: 915-928 MHz (Asia)
- AU915: 915-928 MHz (Australia)
Use Cases
Common applications include:
- Environmental monitoring (temperature, humidity)
- Asset tracking (GPS location)
- Smart agriculture (soil moisture, weather)
- Smart cities (parking, waste management)
- Building automation (HVAC, lighting)
Limitations
Be aware of:
- Small payload sizes (typically 51-222 bytes)
- Limited downlink capability
- Not suitable for real-time applications
- Regulatory duty cycle restrictions
