Wi-Fi R-MESH

Overview

Wi-Fi R-Mesh is a tree-topology mesh network designed to extend Wi-Fi coverage, enabling stations far from the AP to also maintain stable network connectivity. The following is the network topology diagram:

Wi-Fi R-Mesh implements data forwarding directly at the Wi-Fi driver layer, consuming less RAM and MCU resources.

With minimal software processing required, nodes can achieve high throughput and extremely low data latency even after several hops.

Advantages

A software-unsensible mesh network

  • All Mesh protocols are implemented at Wi-Fi driver layer. Both root nodes and child nodes are regarded by the application as standard Wi-Fi stations connected to the AP.

  • No updates are required for Wi-Fi configuration programs.

Rapid pairing and switching within microseconds

  • Child nodes can rapidly switch to a new parent node with better signal quality without interrupting data communication.

  • If the parent node encounters a problem (such as power off or hang), the child node can rapidly detect the issue and switch to an alternative parent node without interrupting data communication.

  • A node can migrate all its child nodes together to a new parent node while maintaining uninterrupted data flow.

High throughput and low data latency

  • R-Mesh forwarding bypasses the TCP/IP protocol stack, implemented directly at the driver layer, thereby consuming less RAM and MCU resources.

  • With extremely short software processing time, better throughput and low data latency can be achieved even after several hops.

Network stability

  • Simplified software architecture eliminates complex routing table algorithms, ensuring network stability.

  • Traditional mesh network issues like loops do not occur.
