A startup named Luma presents a means to ensure home wifi installations do have any connection dead spots-- a "surround wifi" system consisting of multiple routers.
Luma routers are available as a 3-pack, and form a single network once set up. The company claims the routers "always offer peak performance and speed" by automatically tuning signals according to user position, making it sound like a consumer version of the mesh networks found in large enterprise environments.
Each router carries two dual-band 2GHz and 5GHz radios using 802.11ac Wave 2 wifi.
