CWSP - Chap 12. Integrated Services (IS)

Hello fellow Wi-Fi enthusiasts.
I have a question about the Chapter 12: Section WLAN Architecture Capabilities Overview=>[b]Integrated Services[/b]. (CWSP official PW0-204 study guide)
The last sentence states "The IS mechanism normally takes place inside a WLAN controller when lightweight APs are deployed"
[b]Is that statement correct???????[/b]
I would have thought the IS takes place inside the lightweight AP. I didn't think an 802.11 frame could traverse through a wired DS before arriving at the controller for the IS?
What the sentence in Chapter 12 tells me is an 802.11 frame would have to traverse through the cable->to a switch->then back through a cable before reaching a controller where the IS occurs.
please explain?

Nevermind, I found the answer to my problem.
I forgot that [b]an IP encapsulation tunnel such as GRE, LWAPP or CAPWAP is used, thus the 802.11 frame can traverse the 802.3 Ethernet.[/b]
