┌─────────────────┐
│   Application   │ Layer 3: Application Layer
├─────────────────┤
│    LoRaWAN      │ Layer 2: MAC Layer (Data Link)
├─────────────────┤
│      LoRa       │ Layer 1: Physical Layer
└─────────────────┘
  • Physical Layer (Milesight AM307)
    • Handles radio modulation
    • Manages RF parameters: Frequency, Spreading Factor (SF), Bandwidth, and Transmission Power
  • MAC Layer (Device EUI, APPEUI, Application Port, Application Key)
    • Manages network access
    • Device activation (OTAA/ABP)
    • Handles: Message formatting, Security, Channel access, Adaptive Data Rate (ADR)
  • Application Layer (TTS)
    • Carries the actual payload
    • Handles end-application data
    • Manages application-specific encoding/decoding

2. Network configuration​

  • Device EUI

    • A globally unique 64-bit identifier for each device
    • Similar to a MAC address for LoRaWAN devices
    • Format: 8-byte hexadecimal number (e.g., 70B3D57ED0008C3D)
    • Used for device identification and authentication

  • APP EUI (JoinEUI)

    • Globally unique identifier for the application/joining server

    • Used during the device activation process

    • 64-bit identifier that helps route messages to the correct application

      appEUI

  • Application Port

    • Used to multiplex different data types/applications on the same device
    • Values range from 1 to 223
    • Helps distinguish between different types of payloads

  • LoRaWan Versiom

    • Specifies the protocol version (e.g., 1.0.2, 1.0.3, 1.1)
    • Determines available features and security mechanisms

  • Work Mode

    • Defines how the device operates (e.g., Class A, B, or C)

    • Class A: Most energy efficient, bidirectional communication. This device is class A device.

    • Class B: Scheduled receive windows

    • Class C: Continuously listening

      networkconfiguration

  • Join Type

    • OTAA (Over-the-Air Activation): Dynamic secure activation
    • ABP (Activation By Personalization): Static activation with pre-programmed keys

  • Application Key

    • 128-bit AES key used for secure device activation in OTAA(Over-The-Air Activation)

    • Root key for deriving session keys

    • You can generate from the TTS and copy paste here

      AppKey

  • Rejoin Node

    • Configuration for periodic rejoin requests
    • Helps maintain network security and connection reliability

  • Set the number of detection signals sent

    • Defines how many times the device attempts to send join requests

    • Affects connection reliability and power consumption

      networkconfiguration2

  • Support Frequency

    • Frequency band used for communication (e.g., EU868, US915, AS923)
    • Region-specific and must comply with local regulations

  • Frequency/MHz

    networkconfiguration3

  • ADR Mode

    • Automatically optimizes data rates and power usage
    • Balances range, airtime, and power consumption

  • Spreading Factor

    • Determines the chirp duration (SF7-SF12)
    • Higher SF = longer range but slower data rate
    • Lower SF = shorter range but faster data rate

  • TXPower

    • Transmission power level in dBm
    • Affects communication range and battery life
    • Must comply with regional regulations

  • RX2 Data Rate

    • Data rate for the second receive window
    • Used when the first receive window fails
    • Region-specific parameter

  • RX2 Frequency

    • Frequency used for the second receive window
    • Fixed frequency per region
    • Backup communication channel
