With the right approach, you can optimize your network performance and ensure a reliable connection for all your devices.
What is Wi-Fi Splitting?
Wi-Fi splitting, also known as Wi-Fi network segmentation, is a technique where a single physical Wi-Fi network is divided into multiple virtual networks. This is done to improve network security, enhance performance, and increase overall network efficiency. By splitting the network, administrators can create separate networks for different devices, users, or applications, each with its own set of access controls and policies.
This approach allows administrators to isolate sensitive areas of the network, such as a guest network or an IoT device network, from the main corporate network. This isolation helps prevent lateral movement in case of a security breach, reducing the attack surface and minimizing the risk of data compromise. Additionally, Wi-Fi splitting enables administrators to prioritize traffic and allocate bandwidth more effectively, resulting in better overall network performance.
What are the Benefits of Wi-Fi Splitting?
Wi-Fi splitting offers several benefits, including improved network security, enhanced performance, and better management.
