LoRaWAN Units: Features and Selection Guide
Features of STM32WLE5-Based LoRaWAN Units
These four LoRaWAN Units are based on the STM32WLE5 solution, supporting:
- Global Compatibility: Tailored for different regional frequency bands to meet global communication needs.
- Low Power Consumption and High Sensitivity: Ensures long-range communication with minimal energy usage.
- LoRaWAN Protocol Stack: Built-in protocol stack configurable for Class A, B, and C operation modes.
- Point-to-Point (P2P) Communication: Facilitates direct device-to-device communication when no gateway is present.
- Flexible Configuration: It uses the UART communication interface and AT command set for easy setup.
- High-Performance Rubber Rod Antenna: Optimized design for stable signal coverage and extended communication range.
Applications for these units include smart agriculture, industrial monitoring, environmental monitoring, and other IoT scenarios requiring long-range, low-power communication.

FAQs
What are the ranges of LoRaWAN?
LoRaWAN gateways can transmit and receive signals over a distance of over 10 kilometers in rural areas and up to 3 kilometers in dense urban areas.
What frequency is LoRaWAN Europe?
868 MHz, LoRa transmits over license-free megahertz radio frequency bands: 169 MHz, 433 MHz (Asia), 868 MHz (Europe), and 915 MHz (North America).
What is the rate of LoRaWAN?
The low power, low bit rate, and IoT use distinguish this type of network from a wireless WAN that is designed to connect users or businesses, and carry more data, using more power. The LoRaWAN data rate ranges from 0.3 kbit/s to 50 kbit/s per channel.
