Sub-GHz RF Mesh Master Module

Product ID.：WL31XM

Communication mode：UART(Local), RF(Remote)

WL31XM module, as UN in the fast wireless data transmission Mesh network, can directly communicate with DN so as to satisfy the need for direct access to the terminal equipment of customer device (e.g. HHU). Applicable to AMR/AMI/IoT, it offers best solution for low power consumption, low cost, high efficient, and long distance communication.

  • Main Functions
  • Technical Parameters
  • Anti-interference function. Use low noise, high receiver sensitivity and advanced data encryption technology. High anti-interference function, high communication rate;
  • Wireless communication environment analysis function. Inquire RSSI of communication link between nodes through directive to check current communication quality;
  • Support user device connection. System will allocate one UN channel for user device and strengthen interaction with users;
  • Parameter setting. Directly read and write parameters of DNs.
