Eero is a brand of home Wi-Fi systems designed to provide seamless internet coverage throughout a house. It uses a mesh network technology, which means multiple devices work together to create a strong and reliable signal, eliminating dead zones. This makes it ideal for larger homes or spaces with thick walls. The Eero system typically includes a main router and additional satellite units that can be placed in different rooms. Users can easily set up and manage their network through a mobile app, allowing for features like guest access and parental controls.
