Understand WiFi Mesh (EasyMesh) technology and usage scenarios

What's mesh

WiFi Mesh network (wireless mesh network), also known as“multi-hop”network, is a new wireless networking solution developed based on WiFi technology. Unlike traditional WiFi network, WiFi Mesh network is a network technology based on multi-hop routing and peer-to-peer network, which is a new network structure.

Compared with traditional wireless networks, the transmission distance and mobility of WiFi Mesh network will be greatly improved, especially, it is compatible with the WiFi function. Therefore, WiFi Mesh network is very helpful to increase the transmission distance and mobility of wireless networks, expand the application of wireless networks, and has intelligent features such as network self-organization, automatic repair and roaming.

Why use Mesh technology

In the traditional wireless network, WiFi technology constitutes the internal network. The terminal joins the network through WiFi. The connection port on the device is Ethernet or optical port. In the network deployment, once the wired distance is determined, the location of the device WiFi will also be fixed. If you want to change the location of WiFi, you need to adjust the corresponding wired network, which is more difficult to operate and consumes a lot of time and wiring costs.

Therefore, the traditional WiFi construction method has the shortcomings of high cost, poor flexibility, complex operation, etc. It is not suitable for building online services in scenarios such as high wireless quality and aesthetics, less maintenance investment and weak wired network. Mesh network only needs to install corresponding subnodes, no need to change the wired network, and it is very convenient and fast to set up a network.

What are the advantages of mesh networks over traditional WiFi networks?

Compared with traditional WIFI networking, The scalability and mobility of WiFi Mesh networking has significantly improved. Its self-organizing, self-governing, roaming seamless switching characteristics make WIFI Mesh networking have the following significant advantages:

Simple and fast networking: The installation of Mesh network is very convenient and simple. Connect the main device (controller) to the Internet, place the area that needs online business from the routing agent, and complete the network setup, which is time-saving and convenient. In traditional networking, wired connections are required between each node, which is complex and time-consuming to operate.

Dynamically modify the network layout: When an area needs to add or delete network nodes, only join or remove the corresponding nodes through the ad hoc network nodes. Adding or deleting nodes in traditional networks requires changing physical wiring, which requires a lot of time and material resources.

Flexibility and robustness: When a node in a region fails, the Mesh network will automatically rebuild the network structure to ensure the normal use of the network, without troubleshooting, to avoid the phenomenon that a node fails and results in network congestion in one or more regions.

Suitable scenarios and cost-effective ratio: Mesh network is basically suitable for the current scenarios in traditional networks. In addition, Mesh network has obvious advantages in some scenarios that require fewer wiring, more network nodes and lower costs.

MESH technology's vision for the future

Mesh plays an important role in device interconnection under the trends of cloud management, interconnection of everything, and the Internet of Things. Whether in large or small places, Mesh networking is favored by all fields because of its simple and fast networking, dynamic modification of network layout, extremely low construction cost and short construction cycle, saving manpower and manpower, flexibility and robustness. Mesh technology will also continue to optimize and become more intelligent to accommodate more scenarios.

With the rapid development of network, the cost, complexity and maintainability of network are more and more stringent in various fields. These requirements constantly urge the existing network to optimize or update, and create new network schemes. Mesh networking is currently a competitive way of networking.
