Wireless Mesh:
Essentially, the router is networked through WiFi.
As we all know, WiFi in the process of transmission, such as obstacles, such as doors, Windows, walls, etc., will be attenuated, and the network effect will decrease accordingly as the propagation distance becomes farther.
Almost every home now has Wi-Fi, and some have more than one. Therefore, there are multiple Wi-Fi signals in the same space and time, which sometimes causes signal channel congestion, and the network signal is not as stable as the wired Mesh.
However, wireless Mesh wins in the simple operation, without any networking foundation and redundant operations, a look will start in seconds. Wireless Mesh is currently not deployed in advance of the network cable, want to achieve the whole house WiFi is the only choice.
Wired Mesh:
Wired Mesh has higher requirements on the difficulty of networking operations, which requires advance planning and a certain networking foundation.
The wired Mesh requires network cables to connect all routers together. If the room where the routers are placed is far away, the network cables need to cross mountains to connect to each other. And it is best to place the router near the power supply position, otherwise it also needs to pull the plugboard to connect. The network cable and power cord exposed to the air will greatly reduce the simplicity and beauty of the display. However, wired Mesh uses network cables to connect the network, which is not easy to be interfered with, and we do not have to worry about the problem of network speed attenuation in the transmission process, and the network speed is faster and the coverage is wider, and it will be more stable.
Wired Mesh network effect is better, whether the network speed, coverage area and stability are better than wireless Mesh;

Wireless Mesh operation is simple, you can add a new router at any time, no need to advance wiring, more convenient.
It is recommended that friends who have high network requirements and a certain basis for networking choose wired Mesh, and there is no advance wiring, networking white and hand residual party to choose simple and easy to operate wireless Mesh.
In addition, wired and wireless Mesh can be mixed.
Mesh network is \"wireless grid network\
Wireless mesh can communicate cooperatively with other networks, and is a dynamic network architecture that can be continuously expanded, and any two devices can maintain wireless interconnection.
In Mesh networking, factors such as channel interference, hop number selection and frequency selection should be considered comprehensively. This section takes WLANMESH based on 802.11s as an example to analyze various possible networking schemes. The following describes single-frequency networking and dual-frequency networking schemes and their performance.
In multi-channel access of wireless Mesh network, MP nodes in the network can only listen to one channel at a time. In order to use multi-channel, nodes have to dynamically switch between available channels, which requires a coordination mechanism to ensure that the two nodes of communication work on the same channel.
