Run two interfaces on one network card

Is it possible to run two different network interfaces (e.g. being connected to two different wlan-networks) on one card in parallel on linux? If yes, how? If no, why not (I would be glad about a bit technical background). Update: I read a bit, and found out that it is possible to have several ip addresses assigned to the same network card (http://www.tecmint.com/create-multiple-ip-addresses-to-one-single-network-interface/) , but my problem is that I want to be connected to several wlan-networks (one ad-hoc-network and one usual network) in parallel. Is that possible? Due to a lack of a running unix os I am not able to check that. After request: My current network card is Intel Centrino Advanced-N 6230, but my final target is to do that on android, too (I thought that should be possible after android is a modified linux.... But my first approach would be on a usual pc, specs as above)
