Wi-Fi Mesh is a wireless network system that significantly improves the coverage range of Wi-Fi signals. Espressif’s ESP-Mesh-Lite is a Wi-Fi Mesh networking solution based on the Wi-Fi protocol. It supports a large number of devices distributed in indoor and outdoor areas to connect to the same network. This solution provides users with fast, stable, and secure Wi-Fi coverage. ESP-Mesh-Lite is compatible with Espressif's Wi-Fi SoCs such as ESP32, ESP32-C, ESP32-S, and is suitable for automation scenarios that require multi-device networking deployment and group control, including smart homes, smart irrigation, plant lighting, solar power generation, and more.
ESP-Mesh-Lite Network Architecture
ESP-Mesh-Lite network architecture is built upon the concept of wireless self-organization, aiming to create a flexible and reliable IoT networking solution. Below is a comparison between the working principles of ESP-Mesh-Lite network architecture and traditional Wi-Fi networks. The dashed lines in the diagram represent possible connection paths for the devices, and the actual selection of their parent nodes will depend on factors such as signal strength and device hierarchy.

ESP-Mesh-Lite Network
In the Espressif ESP-Mesh-Lite network, all terminal devices can connect to adjacent devices without being limited by the position and capacity of the router. This network architecture not only enables a wider Wi-Fi coverage area but also supports the connection of more devices.

Traditional Wi-Fi Network
In a traditional Wi-Fi network, all terminal devices need to be directly connected to the router when joining the network. This limits the coverage area of Wi-Fi to the location of the router, and the number of devices that can be connected is also limited by the capacity of the router.
Application
ESP-Mesh-Lite meets the diverse communication needs of applications like smart homes, smart charging, and smart agriculture. It enables efficient connections between smart devices, promoting seamless interaction.

Advantages
Self-Forming and Self-Healing
High Throughput
Multiple Device Connectivity
Terminal devices automatically connect to stronger signal nodes to form an ESP-Mesh-Lite network. When any node in the network disconnects, other nodes automatically reconnect, enabling network self-healing. This mechanism ensures that even if some devices in the mesh network fail, other devices can still maintain stable connectivity.
Devices in the ESP-Mesh-Lite network connect via Wi-Fi and they connect to each other. Compared to Thread, Zigbee, and Bluetooth Mesh networks, Wi-Fi connections offer higher network transmission and device communication rates. This makes the solution suitable for high-throughput scenarios such as simultaneous device reporting and OTA.
The ESP-Mesh-Lite network allows various types of Wi-Fi devices to connect and supports direct internet access for each device.
The ESP-Mesh-Lite network does not require a gateway or border router, and any device in the network can connect to adjacent devices, making it easy to expand the network coverage.
Users only need to add ESP-Mesh-Lite initialization and modify the network configuration to quickly migrate ESP-Mesh-Lite to existing Wi-Fi applications, reducing development and maintenance costs.
ESP-Mesh-Lite is based on standard Wi-Fi connectivity and it can use standard WPA2 network security among the mesh nodes to ensure communication security.
