The Ayrstone AyrMesh Hub is the building block of your AyrMesh Network. Mounted at a high elevation outside, each compact, rugged AyrMesh Hub can cast its powerful signal to a laptop or other WiFi device up to half a mile away. Additional AyrMesh Hubs, requiring only an electrical connection, can extend your network even further. With clear line-of-sight, AyrMesh hubs can be placed up to 2.5 miles apart, depending on the Hub model.
