Mesh Network vs WLAN"},"content":{"rendered":"\n

The traditional WLAN uses radio frequency technology to replace the old localized network of twisted copper wires with electromagnetic waves,<\/g> and communication in thin-air. Each client accesses the network through a wireless link connected to the AP to form a local BSS. 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. <\/p>\n\n\n\n

What is Mesh Network?<\/h2>\n\n\n\n

However, wireless mesh networks are different and belong to multi-hop networks. Although also composed of a router and a client, several nodes constitute a backbone network and are connected to a wired internet network, which is responsible for providing a multi-hop wireless internet connection to the client. Wireless mesh networks remove the cabling requirements between nodes, but still have the redundancy and rerouting capabilities provided by distributed networks.<\/p>\n\n\n\n

The biggest advantage of the mesh network and multi-hop access is that if the nearest AP is congested due to excessive traffic, the data can be automatically rerouted to a neighboring node with less traffic. The packet can also continue to be routed to the next node closest to it, depending on the network, until it reaches the final destination. Compared with the traditional switched network, the wireless mesh network removes the wiring requirements between nodes,<\/g> but still has the redundancy mechanism and re-routing function provided by the distributed network.<\/p>\n\n\n\n

Here are a few advantages of wireless mesh networks:<\/p>\n\n\n\n

  1. Cost-effective: <\/li><\/ol>\n\n\n\n

    In wireless mesh networks, only MPP needs to access the wired network, and so the dependence on cabling is reduced to a minimum, eliminating the investment overhead of purchasing a large number of wired devices and installing them.<\/p>\n\n\n\n
