Mesh networking is a "wireless mesh network". It is a "multi-hop" network. It is developed from ad hoc networks and is one of the key technologies to solve the "last mile" problem. one. In the process of evolving to next-generation networks, wireless is an indispensable technology.
Wireless mesh can communicate collaboratively with other networks. It is a dynamic and continuously expandable network architecture. Any two devices can maintain wireless interconnection. With its multi-hop interconnection and mesh topology characteristics, wireless mesh networks have evolved into an effective solution for a variety of wireless access networks such as broadband home networks, community networks, enterprise networks, and metropolitan area networks.
Wireless Mesh routers form a self-organizing network in a multi-hop interconnection manner, providing higher reliability, wider service coverage and lower initial investment costs for WMN networking.

1. Easy deployment and installation
It is very simple to install the Mesh node. Just take the device out of the box and connect it to the power supply. Due to greatly simplified installation, users can easily add new nodes to expand the coverage and network capacity of the wireless network. In a wireless Mesh network, not every Mesh node requires a wired cable connection, which is the biggest difference from a wired AP.
The design goal of Mesh is to minimize the number of wired devices and wired APs, thus greatly reducing the total cost of ownership and installation time. The cost savings brought by this alone are very considerable. The configuration and other network management functions of wireless Mesh networks are the same as traditional WLANs. Users' experience in using WLANs can be easily applied to Mesh networks.
2. NLOS
Using wireless Mesh technology, NLOS configuration can be easily realized, so it has wide application prospects outdoors and in public places. Users with direct line-of-sight to the transmitter receive wireless signals first, and then forward the received signals to users who are not in direct line-of-sight.
In this way, the signal can automatically choose the best path to continuously jump from one user to another, and finally reach the target user who has no direct line of sight. In this way, users with direct line of sight effectively provide wireless broadband access to nearby users without direct line of sight. The wireless Mesh network's non-line-of-sight transmission feature greatly expands the application fields and coverage of wireless broadband.
3. Stability
The usual way to achieve network stability is to use multiple routers to transmit data. If a router fails, information is sent by other routers over alternate paths. E-mail is an example of this. Email information is divided into several data packets, then sent through multiple routers through the Internet, and finally assembled into information that reaches the user's inbox.
Mesh network is more robust than single-hop network because it does not rely 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 structure, each node has one or several paths for transmitting data.
4. High bandwidth
The physical characteristics of wireless communication determine that the shorter the communication transmission distance, the easier it is to obtain high bandwidth, because as the wireless transmission distance increases, various interferences and other The factors leading to data loss increase. Therefore, choosing to transmit data over multiple short hops will be an effective way to obtain higher network bandwidth, and this is the advantage of Mesh networks.
