Know the dates of the IEEE specifications and the modulation for different rates for 802.11, 802.11a, b, & g. I read a few books on wireless from course technology. I did not choose them because I thought they were the best but because I get them for free because I am a professor. They were not bad though. I also read a number of white papers. You can find many links right off the CWNP web site.
