Industry professionals have tended to view mesh networking from a “realist” point-of-view as a niche solution to be avoided if possible, and have never considered the technology the most popular of Wi-Fi capabilities. This pragmatism is rooted in the typical negative performance implications of mesh networks. Just a few years ago mesh capability was limited to a few highly targeted products that served niche markets for large-scale outdoor deployments or service provider environments. These solutions typically relied on multi-radio mesh units, which provide frequency separation between uplink and downlink traffic paths as well as between upstream and downstream hops, in an attempt reduce the negative performance impact for high bandwidth backhaul links.
However, there exists a growing market for mesh networking that utilizes single-radio mesh units to provide an extension of network access across limited mesh hops for hard to wire locations.
