Mesh networking replaces a single router system with a network (or mesh) of connected routers and antennas that are placed strategically throughout the house. Together, they all operate as a single wireless network, empowering you to move freely between them without having to reconnect each time you cross over into a new coverage area. In a mesh network, each of the mesh nodes covers a specific area. When a connected device leaves that area, the mesh node hands it off to another node can provide better service. This roaming capability is the same technology that provides nearly seamless Wi-Fi coverage at airports and convention centers. The same concept can be applied to home networks. Mesh networking means that as you move around in your house, your devices will hop back and forth between the routers with the strongest signal.
