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
