Could someone please tell me if Wifi uses routing? If so, why and how?

My idea is the wireless router can simply broadcast, and wireless devices within its range can receive the signal. So, no routing protocols should be involved there.

Thanks!

Most Wifi devices that I know of contain a router. But what do I know? I'm just a programmer. The folks over at SuperUser might be better able to answer your question. – Robert Harvey Aug 31 '10 at 15:20

Wifi is just a 'blind' physical data transmission protocol it doesn't involve routing anyway (which is done in the Network layer), see OSI stack for more informations.

Yes, I understood that. I guess the terms "Wifi" and "Wireless LAN" confuses me :) – Barun Aug 31 '10 at 15:43

"Wifi" is a whole class of protocols. The physical layer (i.e. 802.11) does not involve routing, no.
