LoRaWAN Modulation settings (EU band)
- LoRaWAN can auto-magically manage:
- Data Rate
- RF power output
- Done for each end-device separately:
- Optimize for fastest data rate
- Maximize battery life (4-5mA / < 3µA)
- Maximize network capacity
- All these activities based on actual range from the gateway
LoRaWan Network
- Low Power Wide Area Network (LPWAN)
- Bi-directional
- Simple Start network topology
- Low Data Rate, Low Cost, Long Battery Life
- Enables Simple Network Architecture
- No Repeaters
- No Mesh Routing Complexity
- Ideal for:
- Internet of Things (IoT), Machine-to-Machine (M2M)
- Industrial Automation
- Low Power Applications, Battery Operated sensors
- Smart City, Smart Meters, Smart Agriculture
LoRaWan Architecture
- End-Device
- The “Thing” in IoT
- Single-hop wireless communication to one or many Gateways
- Gateway
- Interface the LoRAWaN RF Network to LoRaWaN Backend Services
- Data is “passed through” to Servers
- Connected to Network Server via standard IP connectivity
- Network Server
- Network Server Authenticates data
- If data addressed to Network Server, data is processed
- Else data is forwarded to Application Server
- Connected to Application server via standard IP communication
- Application Server
- Consumer of received data
- Application server decrypts data
- Multiple Application Servers can exist with the same LoRaWaN network
LoRaWAN Network security
- Security Standard 802.15.4 (AES-128)
- Network server authenticates Application Data over network
- Network server cannot decrypt Application Data
LoRaWAN Network Security
- Two-phases end-to-end data security
LoRaWAN technology - advantages
- Long range
- Long battery life
- Low power
- Low cost
- Multi-purpose and multi-usage
