Wireless mesh networks are reliable and offer great redundancy. If one link can no longer operate, all the rest can still communicate with each other, directly or through one or more intermediate links.
Each link can send and receive messages in a wireless mesh network. Each link also functions as a router and can relay messages for its neighbors. Through the relaying process, a packet of wireless data will find its way to its destination, passing through intermediate links with reliable communication. Wireless mesh networks can be configured in a star topology or be made up of multiple types of configuration topologies.
Wireless mesh networks can be configured for both outdoor or indoor applications. Mesh networks are great in urban settings where there are a lot of obstructions (e.g. buildings) to provide a quality network for mobile connectivity, video surveillance, or Wi-Fi. Most wireless mesh networking devices operate in the 2.4GHz, 4.9GHz, or 5GHz frequency bands. The reach in a wireless mesh network can be extend, greater redundancy can be achieved, and improved reliability of the network simply by adding more links. Wireless mesh networks are extremely scalable and can handle hundreds of links. Because the network's operation doesn't depend on a central control point, utilizing multiple links provide a reliable mobile network.
