Spread Spectrum and Modulation/Encoding Techniques used in 802.11 Wireless

The goal of this paper is to educate those curious on how information is sent in wireless LANs. This paper is about the physical way the signal is sent, that is to say we will not be preforming a dissection of the 802.11 protocols but rather the manner in which the ones and zeros make their way through the air. We will be covering the various spread spectrum technologies used such as FHSS, DSSS and OFDM. Beyond the spread spectrum technologies we will also be discussing Barker Codes, CCK, DB/QFSM and other fun stuff, so sit back and enjoy the ride.
