Now we can enable/disable fast roaming via OC200 & Omada Controller & Omada APP. If Omada Controller or OC200 accidentially shuts down, then fast roaming will not work.

For fast roaming you need a controller since fast roaming implies that the controller creates a list of nearby APs which is then sent to clients wishing to roam in order to avoid time-consuming WiFi surveys. It's not just a feature you get with Omada controller, but it won't work at all without a controller.
You can download Omada software controller for free if you need fast roaming and don't want to use an OC200.
