Wireless Protocol Implement - Which Experimental Devices?! Dev.Tools?

Dear All

I just want to implement some sort of Protocol as part of Wireless
protocol suites, actually a MAC Layer protocol for 802.11. I need to
change the Wireless Adapter's default behavior, like dropping bad CRC
packets etc.

In my point of view steps should consist of some sort of Firmware
modification and Driver development, is that correct?

And the question is, How to do that? Are there any well-known
device for experimental purposes? or a suitable one that is
modifiable? or Some kind of Development Kit?

I don't know where to look for.

Looking forward to you kind replies, and opinion


Best Regards
