The Autonomous APs are self-governing APs. It is not possible to advertise a single SSID through multiple APs, which is Ideal for a minimal deployment. On the other hand, the Light Weight APs rely on the central WLAN controller and can advertise a single SSID through multiple APs for large scale mobility and roaming services.
When an AP joins a WLC, a Control and Provisioning of Wireless Access Points protocol (CAPWAP) tunnel is formed between the two devices. In my video, you can see I have created SSIDs for IT, HR, and SALES departments and pushed them to the Light Weight APs.
