Designed to blanket your home with wireless coverage, Wi-Fi systems are a hybrid of sorts, made up of several networking components. There's a main router that connects directly to your modem, and a series of satellite modules, or nodes, that you place throughout your house. They are all part of a single wireless network, and share the same SSID and password. Unlike range extenders, which communicate with the router via the 2.4GHz or 5GHz radio bands, most Wi-Fi system satellites use mesh technology to talk to the router and to each other. Each node serves as a hop point for other nodes in the system. This helps the nodes farthest from the router to deliver a strong Wi-Fi signal as they are talking to other nodes and not relying on one-to-one communications with the router. Not all Wi-Fi systems use mesh networking, however; some use a dedicated radio band to communicate with the router and with each other. As with mesh, the dedicated band frees up the standard-use 2.4GHz bands for client use. |
