What does LoRaWAN stand for? What is the principle of LoRaWAN?
LoRaWAN stands for Long Range Wide Area Network. It is a communication protocol designed to wirelessly connect battery-operated devices to the internet over long distances. LoRaWAN is built on LoRa (Long Range) modulation, which allows data transmission over several kilometers while using very low power, making it ideal for IoT (Internet of Things) applications.
Principle of LoRaWAN:
LoRaWAN operates on a star topology, where end devices communicate with gateways using LoRa modulation, and the gateways, in turn, connect to a central network server via standard IP connections. The key principles include:
- Long Range Communication: LoRaWAN allows communication over several kilometers, depending on the environment (up to 10-15 km in rural areas).
- Low Power Consumption: LoRaWAN is designed for low power, enabling battery-powered devices to last for several years.
- Adaptive Data Rate (ADR): LoRaWAN adjusts the data rate dynamically, depending on the distance between the end device and the gateway, to optimize power consumption and network capacity.
- End-to-End Security: LoRaWAN employs AES-128 encryption to secure communications, ensuring confidentiality and integrity.
- Scalability: LoRaWAN networks can support thousands of devices, making it suitable for large-scale IoT deployments like smart cities, agriculture, and industrial automation.
