Comprehensive introduction to Mesh network technical advantages

Compared with other routing technologies, the Mesh network technology has many advantages and provides a better network environment for users. The following describes the five advantages of the Mesh network technology for your reference. Compared with traditional WLAN, wireless Mesh network technology has several unparalleled advantages:

(1) Fast deployment and easy installation

Installing Mesh nodes is very simple. Just remove the device from the box and connect it to the power supply. You can easily add new nodes to expand the coverage and network capacity of the wireless network. Mesh is designed to minimize the number of wired devices and APS, thus greatly reducing the total cost of ownership and installation time. The cost savings brought by this alone are considerable. The configuration and other network management functions of the wireless Mesh network are the same as those of the traditional WLAN. the user experience of WLAN can be easily applied to the Mesh network technology.

(2) NLOS)

The use of wireless Mesh Technology can easily Implement NLOS configuration, so it has a wide range of application prospects in outdoor and public places. Users with direct line of sight with the transmitting station receive wireless signals first, and then forward the received signals to non-direct line of sight users. In this way, the signal can automatically select the optimal path to continuously jump from one user to another, and finally reach the target user without direct line of sight. In this way, users with direct line of sight actually provide wireless broadband access for nearby users without direct line of sight. The wireless Mesh network technology is capable of non-line-of-sight transmission, which greatly expands the application and coverage of wireless broadband.

(3) Robustness

A common way to achieve network robustness is to use multiple routers to transmit data. If a router fails, the information is transmitted by another router through the backup path. The Mesh network technology is more robust than a single hop Network because it does not depend on the performance of a single node. In a single hop Network, if a node fails, the entire network will be paralyzed. In the Mesh network technology structure, each node has one or several data transmission paths. If a fault or interference occurs on the nearest node, the data packet is automatically routed to the backup path for further transmission. The entire network is not affected.

(4) Flexible Structure

In a single hop Network, the device must share the AP. If several devices need to access the network at the same time, communication congestion may occur and the system running speed may decrease. In a multi-hop Network, devices can connect to the network through different nodes at the same time, so the system performance will not decrease. Mesh Network Technology also provides greater redundancy mechanisms and communication load balancing functions.

(5) high bandwidth

The physical characteristics of wireless communication determine that the shorter the communication distance, the higher the bandwidth, because with the increase of wireless transmission distance, various interference and other factors that lead to data loss will increase. Therefore, selecting to transmit data through multiple short hops is an effective way to obtain higher network bandwidth, which is the advantage of Mesh network technology.

In Mesh network technology, a node can not only transmit and receive information, but also act as a router to forward information to nearby nodes, as more nodes are connected to each other and the number of possible paths increases, the total bandwidth is also greatly increased.

In addition, because the transmission distance of each short hop is short, the power required for data transmission is also small. Since multi-hop networks usually transmit data to neighboring nodes at a low power, the wireless signal interference between nodes is also small, and the channel quality and channel utilization efficiency of the network are greatly improved, therefore, higher network capacity can be achieved. For example, in a high-density urban network environment, Mesh network technology can reduce mutual interference between adjacent users using wireless networks and greatly improve channel utilization efficiency.
