Sub-GHz RF Mesh Gateway Module

Product ID.： WL31XG

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

WL31XG module works as CN in fast wireless transmission Mesh Network, being responsible for forming, managing and operating micro-power network. 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;
  • Self-networking and self-maintenance function. Automatically form the network after setting the parameters and constantly learn and maintain by itself in operation;
  • Real-time network information query. Network node online situation, repeater tier, network route and route reliability, etc. can be checked at any time;
  • Self-diagnosis function. Analyze failure of communication with target nodes and position communication link fault;
  • Event report function. Support any node to automatically send data besides transferring down-link request data and up-link response data.
