Instead of relying on a single router, a mesh network uses multiple routers to more evenly distribute the wireless network over a larger area. They are intended to eliminate the dead spots often found in large homes from a single Wi-Fi router.
What is a Mesh Network? Everything you need to know
Mesh networking relies on a set of mesh routers linked together. This isn’t a new technology; mesh networking has been used by the military since the 1980s, for example. But the first mesh routers became widely available to home and consumer buyers with models like the Eero and Orbi starting around 2016.
A mesh router is not one device like a traditional router; there can be two, three or even more routers in a mesh system. One of these routers is a gateway that connects to the Internet, usually through the DSL or cable modem.
But each mesh router in the system is a node that “talks” to each other, acting as the primary router, capable of communicating with all devices within range. This allows a mesh router system to cover a large home with Wi-Fi without dead spots.
