What is a WiFi Zone Controller?
Cloud Ruckus is a cloud/internet-based WiFi controller. When using wireless hardware capable of forming one WiFi zone (i.e. multiple wireless access points all running one SSID) as described on our WiFi options page, a controller is used to perform the initial Wi-Fi setup, but also used to manage and maintain the system going forward.
This management and maintenance will involve diagnostics, troubleshooting, firmware upgrades, password changes etc. It is not possible to reliably run a WiFi zone/system without a zone controller.
