LoRa (Long Range) is a Low-Power Wide-Area Network (LPWAN) technology widely used in the Internet of Things (IoT). LoRa devices
primarily operate in unlicensed Industrial, Scientific, and Medical (ISM) frequency bands, which are freely available globally.
• Frequency Bands: Mainly uses 863–870 MHz, with some countries also using 433 MHz.
• Regulations: LoRa devices are classified as general low-power devices and are subject to the ERC 70-03 regulations. If they do not
use "Listen Before Talk" technology, they must comply with a duty cycle limit of 0.1% to 1%.
• Frequency Band: Uses 902–928 MHz, which is divided into dedicated uplink and downlink channels.
• Channel Structure: The U.S. LoRa band includes 8 sub-bands, each containing 8×125 kHz uplink channels, 1×500 kHz uplink channel,
and 1×500 kHz downlink channel.
• Frequency Bands: Uses 779–787 MHz and 470–510 MHz.
• Channel Definition: In the 410–441 MHz band, approximately 32 channels are defined for LoRa technology.
1. Long-Range Communication
LoRa is renowned for its long-distance communication capability, typically reaching several kilometers to over ten kilometers. The actual
range depends on factors such as the environment, antenna, and transmission power.
2. Low Power Consumption
LoRa devices consume minimal energy during communication, making them suitable for battery-powered IoT devices and extending their
operational lifespan.
3. Strong Anti-Interference Ability
Leveraging spread-spectrum communication principles, LoRa technology demonstrates robust anti-interference capabilities, ensuring stable
communication even in complex environments.
• Remote Asset Tracking and Management: Applied in logistics, supply chain management, and other fields to enable real-time tracking
and monitoring of remote assets.
• Agriculture and Environmental Monitoring: Used for intelligent monitoring in scenarios such as soil moisture detection and weather
stations.
• Smart Cities: Deployed in IoT applications for sensor networks, intelligent transportation, public safety, and other aspects of smart city
infrastructure.
• Frequency Band Regulations: Different countries and regions have varying regulations and restrictions on radio frequency usage.
When using LoRa, it is essential to comply with local laws and regulations.
• Device Compatibility: LoRa devices from different manufacturers may differ in frequency band support, communication protocols, etc.
Therefore, pay attention to compatibility when selecting devices.
In summary, as a low-power, long-range wireless communication technology, LoRa holds broad application prospects in the IoT field.
