Wireless Mesh Network's advantage

- May 13, 2019-

Wireless Mesh networks have several unparalleled advantages over traditional WLANs:


Easy to deploy and install

Installing the Mesh node is very simple. Take the device out of the box and plug it in. By greatly simplifying the 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.


Mesh's design goal 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 from this alone are considerable. The configuration of the wireless mesh network and other network management functions are the same as those of the traditional WLAN. The experience of the user using the WLAN can be easily applied to the Mesh network.


NLOS

NLOS configuration can be easily implemented using wireless Mesh technology, so it has broad application prospects in outdoor and public places. A user having a direct line of sight with the transmitting station first receives the wireless signal and then forwards the received signal to the user of the non-direct line of sight. In this way, the signal can automatically select the best path to continuously jump from one user to another and eventually reach the target user without direct line of sight. In this way, users with direct line of sight actually provide wireless broadband access to nearby users without direct line of sight. The ability of wireless Mesh networks to non-line-of-sight transmission greatly expands the application area and coverage of wireless broadband.


stability

The usual way to achieve network stability is to use multiple routers to transfer data. If a router fails, information is transmitted by other routers through the alternate path. E-mail is an example where the mail message is divided into several packets, which are then sent over the Internet via multiple routers and finally assembled into the information in the user's inbox. A mesh network 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 collapse. In the Mesh network structure, each node has one or several paths for transmitting data. If the nearest node fails or is disturbed, the packet will be automatically routed to the alternate path for transmission and the entire network will not be affected.


Flexible structure

In a single-hop network, devices must share APs. If several devices are to access the network at the same time, communication congestion may occur and the system may be slowed down. In a multi-hop network, devices can connect to the network through different nodes at the same time, so it does not cause system performance degradation.


The Mesh network also provides greater redundancy and communication load balancing. In a wireless mesh network, each device has multiple transmission paths available, and the network can dynamically allocate communication routes according to the communication load condition of each node, thereby effectively avoiding communication congestion of the nodes. Single-hop networks do not dynamically handle communication interference and overloading of access points.


High bandwidth

The physical characteristics of wireless communication determine that the shorter the distance of communication transmission, the easier it is to obtain high bandwidth, because as the wireless transmission distance increases, various interferences and other factors that cause data loss increase. Therefore, choosing to transmit data through multiple short hops will be an effective way to obtain higher network bandwidth, which is the advantage of Mesh network.


In a mesh network, a node can not only transmit and receive information, but also act as a router to forward information to its neighbors. As more nodes are connected 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 to transmit data is also small. Since multi-hop networks typically use lower power to transmit data to neighboring nodes, the wireless signal interference between the nodes is also small, and the channel quality and channel utilization efficiency of the network are greatly improved, thereby enabling higher network capacity. For example, in a high-density urban network environment, the Mesh network can reduce the mutual interference of neighboring users using the wireless network, and greatly improve the channel utilization efficiency.


Can be used outdoors

The mesh wireless network is a double-edged sword. A wireless mesh network can extend the infrastructure of a wireless LAN to where it is not possible to equip an access point with cable, but it also pays for the down link throughput downtime for customers connected to mesh mesh wireless access points. The same is true. In addition, power support is required at the far end. For example, bus stations already have power support, and management of hotspot control panels requires almost no bandwidth. Access points at bus stops will not serve Wi-Fi clients. Instead, it has its own RJ-45 port that can be enabled and configured to provide the virtual LAN needed for the hotspot.
