Microcontroller is laboratory projects need, want to ask is there any wifi source of the agreement?

The boss wanted to study 802.11 g or 802.11 n, the CSMA/CA protocol of parts are useful to the RTS/CTS mechanism, he wants to know our own can modify this time interval, so be on the single chip microcomputer to realize,

But not only by ordinary MCU communication module is not achieve them, existing of WIFI module on the market will provide the base development source code? Is that you can own programming,
Or is there a man can tell me how should be done? The boss of this idea is feasible?

A man understand guidance please, thank you very much!
