What are the outstanding advantages of Mesh network compared with traditional network structure?

Since the birth of the network transmission technology in the 1960s, it has provided stable network links and a large amount of data traffic during the development period. Among them, the mesh network is particularly outstanding. However, in the early stage of the mesh network, due to its complicated structure and unappreciated by people, it was gradually taken seriously by people because of its outstanding advantages in the development process. Here is a brief introduction to the advantages of mesh networks compared to traditional network structures.

Fast deployment and simple installation:

Wireless Mesh networks are faster to deploy and less difficult to install. Since the data is transmitted wirelessly, the user simply takes the device out of the box and connects it to the power supply, and then enters the configuration page. This is because in a wireless Mesh network, except for a small number of node devices that require a network cable and an AP connection, most devices require only one power cable, no network cable and AP connection, and all data is wirelessly transmitted. In this way, not only the connection speed is greatly saved, but also the difficulty of the wired layout is reduced, which is very convenient.

Wireless transmission of data between nodes:

We know that in the current common LAN, all data is connected to a single AP for transmission and reception. In a local area network, if there is a central AP, there is only one road for data transmission, so in actual use, it is easy to cause data congestion or failure (such as AP connection disconnection or equipment damage, etc.). However, in a wireless mesh network, due to the characteristics of its multi-hop network, one node can connect to at least two other nodes. When a node is blocked or unresponsive, the wireless mesh network can select other nodes for data transmission according to the situation. In other words, the wireless mesh network has at least one alternate path, so the reliability of data transmission is very high.

Implement non-line-of-sight transmission:

Another feature of wireless mesh networks is the ability to provide non-line-of-sight transmission. The so-called non-line-of-sight transmission refers to providing a transmission function in an area outside the coverage of the original signal. This is also well understood, because each node has the characteristics of simultaneous reception and transmission, which is equivalent to expanding the coverage of the network to a certain extent. For example, a traditional network has only one data sending node, which is the central node that connects to the AP. In the coverage of the central node, data transmission and transmission are effective, but the distance is far away and is invalid.

In a wireless Mesh network, each node is equivalent to a repeater, which is equivalent to expanding the scope of data coverage, and can provide a network for users outside the line of sight of the AP connected to the AP, greatly improving the application field of the wireless network. And coverage.

Flexible structure:

In fact, the flexibility of the structure is related to robustness, that is, there is no data blockage or node failure. When data needs to be transmitted between two nodes in a wireless mesh network, the node can automatically select a forwarding path with a faster response time and a higher transmission speed according to the connection situation and the response situation, thereby avoiding node communication congestion. Even for some nodes with extremely high privileges, multiple nodes can be selected at the same time to transmit data to multiple targets at the same time, which greatly saves data transmission time and improves efficiency.

High bandwidth and high transmission efficiency: Bandwidth is always an intractable problem. Because of the characteristics of wireless communication, bandwidth is easy to increase only when the transmission distance is short. However, the transmission distance of data is closely related to the signal strength, while the traditional single-center mode coverage area is limited. Due to the non-line-of-sight transmission characteristics of the wireless Mesh network, the signal coverage is better and the strength is higher, and the total bandwidth is more easily improved. In addition, due to the role of the node relay, the wireless Mesh network signal coverage is excellent, so the power required for transmission is reduced, which is also helpful for energy saving.

Wireless Mesh network greatly enhances signal coverage:

It is not difficult to see from the above description that the advantages of the wireless Mesh network are very prominent. It can solve the problems of the current star-shaped LAN and bus structure LAN, and can also expand more aspects related to security, stability and high bandwidth. The function. If it can be applied to new wireless network products, it is expected to lead the further development of network technology, achieving higher transmission speed and wider signal coverage.

The development of network technology has brought tremendous changes to human society. It has made people's communication easier, information transmission has become more convenient, and even contributed to the technological revolution and industrial upgrading, and reduced the cost of communication between people. The equality of global information exchange. However, the traditional LAN technology has a certain bottleneck and limitation in the development process due to technical limitations. The solution to this problem is to “return to the original heart” and re-enter the Mesh network, that is, the network. Network structure.
