A Mesh Wi-Fi system is a network setup that uses multiple devices, called nodes, to provide seamless internet coverage throughout a home or office. Unlike traditional routers, which can create dead zones, mesh systems work together to eliminate weak signals by communicating with each other, ensuring a strong connection in every corner. These systems are easy to install and manage, often using a mobile app for setup and monitoring. They are ideal for larger spaces or areas with thick walls, as they can be expanded by adding more nodes to improve coverage and performance without complicated configurations.
