WiMax deployments can incorporate mesh technology to support multiple access points over non-line of sight networks. Mesh technology is very useful for wireless systems located in areas where numerous physical obstructions impede the transmission of signals. This is not a new technology and has been widely used in the deployment of WiFi networks. Mesh technology is also widely used for military purposes to ensure constant and uninterrupted radio communication between base unit facilities.
WiMax mesh networks can be deployed in highly urbanized areas where buildings, houses and other physical obstructions prevent line of sight transfer of signals. Suburban and countryside WiMax networks can also deploy mesh technology to skirt over natural barriers such as hills, trees, or rows of houses. The capability of a mesh network for delivering distributed signals to subscribers makes it an ideal configuration for carriers using WiMax technologies. Their subscribers will not experience spotty signals or service interruptions caused by physical obstruction.
In a WiMax mesh network, a main wireless backhaul circuit could be the source of the entire bandwidth for a given area. Because modern neighborhoods are quite congested, meshing enables those far away from the main backhaul to get signals from other circuit networks distributed in the locality. It works like the relay system of radio stations. Access points however can be located over the rooftops of subscribers or on buildings or stop light signals if the mesh network is within a city. Through this technology, WiMax connectivity would be more stable and will not be too reliant on a single line of sight tower.
