What are the advantages of using wireless mesh networks in enterprises?

In the traditional wireless network usage environment, imagine that when we use the network in an office environment, such as video conferencing, sending and receiving files, if the network is delayed and stuck, it will greatly affect efficiency. At a time when time is so precious, this will be a fatal disadvantage. If the usage environment is changed to a specific place, such as a school, hospital or other enterprise or institution, the network delay will also cause a significant impact. In a word, when the network becomes an indispensable part of people's lives, the network delay and stuck will cause inconvenience to people's daily life.

Why is wireless mesh technology suitable for enterprises?

In order to truly enjoy the ocean of the Internet anytime and anywhere, a wireless mesh network with convenient wiring and flexible structure has developed rapidly. It is a decentralized multi-hop network form that allows users within the coverage of the network to have high-speed wireless access to the Internet at any time and any place.

In a traditional wireless LAN, each client accesses the network through a wireless link connected to an AP. If users want to communicate with each other, they must first access a fixed access point (AP). This network structure is called a single-hop network. In a wireless mesh network, any wireless device node can act as an AP and a router at the same time. Each node in the network can send and receive signals, and each node can communicate directly with one or more peer nodes.

One of the advantages of wireless Mesh network is high stability

As mentioned above, in traditional wireless LAN, each client accesses the network through a wireless link connected to the AP. If the data transmission is large, it is easy to cause line congestion. However, in Mesh wireless network, because of the multi-node multi-hop network characteristics, when each node is congested, the wireless Mesh network can select other nodes for data transmission according to the situation. Because there are other nodes for data transmission, the network stability is more reliable than the traditional LAN.

For example, during data transmission, channel congestion can be avoided due to the relationship between multiple nodes. However, when there is no congestion, the node can automatically select the forwarding path with the fastest response time and the highest transmission speed based on the connection and response conditions.

The attenuation of bandwidth caused by wireless relay is a big problem. Generally speaking, the bandwidth is easy to increase only when the transmission distance is short. However, the signal strength caused by some reasons will affect the transmission distance of the data, and the coverage area of ​​the traditional single-center method is also limited. Due to the non-line-of-sight transmission characteristics of wireless mesh networks, the signal coverage is better and the strength is higher, making it easier to achieve an increase in total bandwidth. At the same time, due to the role of multi-node relays, the power required for transmission is reduced, which is more energy-efficient.

Advantage 2 of wireless mesh network: simple installation and fast deployment

At the same time, because it does not require too many network cables for configuration, it also has the advantages of fast deployment and low installation difficulty.

Wireless Mesh devices only need a power cord to enter the settings page and the device will set itself up. Except for a few node devices that need to be connected to the AP via a network cable, most devices only need a power cord and do not need to be connected to the AP. All data is transmitted wirelessly. Therefore, the trouble of wiring is saved and the space is used to the maximum extent.

One of the most troublesome issues with wired networks is cabling. The picture shows the standardized cabling in a network room.

Another feature of wireless mesh network is that it can provide non-line-of-sight transmission. The so-called non-line-of-sight transmission refers to providing transmission function in areas outside the coverage range of the original signal. This is also easy to understand. Each node mentioned above can communicate directly with one or more peer nodes. In other words, each node is equivalent to a repeater, which invisibly expands the scope of data coverage and can provide a network for users outside the line-of-sight of the node connected to the AP.

Wireless mesh is suitable for small and micro enterprises and business scenarios. It is easy to install. Except for a few devices that need to be wired, other devices only need a power cord and can be set up by themselves after powering on. The price is also cheaper than the traditional AC+AP model.
