Espressif announces an innovative Wi-Fi Mesh networking solution that allows for unrestricted device quantity and coverage area.

Espressif Systems (688018.SH) introduces ESP-Mesh-Lite: a Wi-Fi-Based mesh networking solution for seamless connectivity across larger areas, enabling the effortless interconnection of numerous devices. This innovative Wi-Fi Mesh technology offers flexible and reliable IoT networking, ensuring that users enjoy fast, stable and secure Wi-Fi coverage, without the constraints of device quantity or router placement.

ESP-Mesh-Lite Network Architecture

In a traditional Wi-Fi network, all terminal devices need to establish direct connections with the router, limiting Wi-Fi coverage due to router placement, while also imposing capacity limitations to the number of devices that can be accommodated. However, the network architecture of ESP-Mesh-Lite  materializes the concept of wireless self-organization, enabling terminal devices to connect with neighboring ones and, therefore, eliminating their reliance on router placement and any capacity constraints. This architecture not only extends Wi-Fi coverage but also supports the interconnectivity of a larger number of devices, which enhances user convenience significantly. 

Traditional Wi-Fi Network vs ESP-Mesh-Lite Network

In the ESP-Mesh-Lite architecture, sub-nodes have a direct access to external networks. Thus, without the need for any root node application layer involvement, seamless connectivity can be achieved at the root node's application layer.  Consequently, the ESP- Mesh-Lite architecture simplifies application logic development, while also enabling effortless scalability across different device categories. Furthermore, the mesh network continuously supports the connection of other standard Wi-Fi devices which enhances the network’s overall adaptability.
