There seem to be several embedded solutions which make use of PRISM based 802.11b cards. This seems like a pretty easy solution, even for smaller embedded processors. However, looking around for these cards, it seems they are becoming harder and harder to find. Is it going to be impossible to get them within the next couple years?
Is there a better solution? I can't seem to find one. The 802.11 modules from Digi seem interesting, and while $140 per module is a little high, I'm not going to shell out $1500 for their developement kit just to investigate.
Thanks.
