I have been looking for some wifi chip(set) to be able to use in our systems and it has turned out it is impossible to get one which is documented in a way we could write our own driver so our tcp/ip stack under dps would treat it as yet another medium, like it does with Ethernet or via PPP and sort of. What I don't get is *why* do they keep things so secret? When wifi was starting there was some PRISM hardware which had been documented; at some point it was bought and *all* documentation was carefully made extinct. Now all you can buy are modules which will do the tcp/ip for you, you can only ask for a tcp connection *they* will make and maintain etc. Why is that, does anybody know? I am trying to understand the motivation of those who pull the strings to keep these data so secret, perhaps if I once understand it I can advance a step closer. I am really reluctant to spend a year of my life writing my firmware for some wifi radio (these can be bought), not least because I have better things to do with the active years I can hope to have left.
