LoRa and LoRaWAN Wireless Technology
LoRa or long range is a physical proprietary radio communication technique. It is based on spread spectrum modulation techniques derived from chirp spread spectrum (CSS) technology. LoRa is a long range, low power wireless platform that has become the de facto wireless platform of Internet of Things (IoT). LoRaWAN defines the communication protocol and system architecture. The LN502, supporting Modbus protocol and serial communication, is ideal for LoRa-enabled devices in the IoT system.
Multiple LoRa Frequency Bands
The LN502 supports the following license-free sub-gigahertz radio frequency bands,
- EU868 (863 to 870 MHz) in Europe
- AU915/AS923-1 (915 to 928 MHz) in South America
- US915 (902 to 928 MHz) in North America
- IN865 (865 to 867 MHz) in India
- AS923 (915 to 928 MHz) in Asia
- KR920 (920 to 923 MHz) in South Korea
- RU864 (864 to 870 MHz)
