A good overview and pretty detailed article on everything from "what is 802.11?" to "hidden node" issues to why 11g hasn't shown up yet. I highly suggest folks check this out.
Tim -- http://www.e-insite.net/ednmag/index.asp?layout=article&stt=000&articleid=CA213405&pubdate=5/2/2002 Duking it out on the wireless network Wireless communication can be a bitter battle, and IEEE 802.11 is well-armed for the job. But with multiple versions of the standard and a turf fight over the 11g extension, you might wonder whether chip makers are struggling to dominate the standard or to form flexible networks. Put up your dukes and log in. By Joshua Israelsohn, Technical Editor -- EDN, 5/2/2002 IEEE 802.11 does not specify a single method of implementing wireless data communications. Rather, it comprises a family of standardssome ratified and others working their way through the ratification process. The 802.11 Working Group is just one of 16 under the IEEE LMSC's (LAN/MAN Standards Committee's) Project 802 (see sidebar "802.map"). The 802.11 WLAN (Wireless LAN) Working Group originally proposed a single MAC (media-access controller) and three PHYs (physical-layer) controllerstwo for RF and one for IR. The standard has evolved as a result of lessons learned during early commercialization efforts. The prominent issues that the market feedback stresses are operating range, throughput rate, channel count, security, robustness, and cost. In response, 802.11 has expanded beyond its original 2.4-GHz spectrum and has considered a wider range of modulation schemes than were originally contemplated.
