LoRaWAN Communication Mechanism

LoRaWAN is an ultra-low power wireless communication technology designed for long-range data transmission and long-term outdoor deployment of IoT devices.

It provides:

• Long communication range (over several kilometers in open environments)
• Ultra-low power consumption suitable for battery-powered devices
• Wide-area wireless coverage without complex wiring
• Private network deployment without telecom subscription fees

These characteristics make LoRaWAN suitable for large-scale IoT deployments such as environmental monitoring, agriculture, and industrial applications.

Regional Frequency Bands

To meet wireless communication regulations in different regions, avoid spectrum interference, and ensure interoperability of LoRaWAN devices, LoRaWAN operates on different frequency bands worldwide:

• European Frequency Band (EU868)
  863–870 MHz band, widely used in Europe and managed by ETSI.

• American Frequency Band (US915)
  902–928 MHz band, regulated by the FCC in the United States.

• Asian Frequency Band (AS923)
  923–925 MHz band, adopted in many Asian countries.

• Chinese Frequency Band (CN470)
  470–510 MHz band, managed by the Ministry of Industry and Information Technology (MIIT) of China.
