Ra-09(H) module is a LoRaWAN module developed by Ai-Thinker CO., LTD and ST in close cooperation.
The chip use for the module is STM32WLE5CCU6, which has 256 KB Flash, 64 KB SRAM, and the core is 32-bit Armยฎ Cortex-M4 running at 48MHz.
Ra-09(H) supports both LoRa modulation and traditional (G) FSK modulation for LPWAN use cases, while the transmitter also supports BPSK modulation and (G) MSK modulation, and the receiver supports (G) MSK modulation. The module has factory built-in AT firmware program, which developers can directly use to connect to LoRaWAN gateway.
What is LoRaWAN Technology
The LoRaWANยฎ specification is a Low Power, Wide Area (LPWA) networking protocol designed to wirelessly connect battery operated โthingsโ to the internet in regional, national or global networks, and targets key Internet of Things (IoT) requirements such as bi-directional communication, end-to-end security, mobility and localization services.
It is a low-power, wide-area networking protocol designed for IoT devices. It operates in the unlicensed radio spectrum, offering long-range communication capabilities while consuming minimal power.
The significant attributes of LoRaWAN that make it ideal for smart building projects include:
- Long Range: LoRaWAN can cover distances of up to 10 kilometers in rural areas and up to 3 kilometers in urban environments, making it suitable for large buildings or sprawling campuses.
- Low Power Consumption: Devices using LoRaWAN can operate on small batteries for years, reducing maintenance costs and ensuring reliable long-term performance.
- High Capacity: A single LoRaWAN gateway can handle thousands of devices, making it scalable for extensive smart building deployments.
- Secure Communication: LoRaWAN offers robust encryption protocols to ensure data security and privacy.
The Ra-09(H) provides ultra-long range and ultra-low power communication for LPWAN applications in the following scenarios:
