Appendix B. Modulation and Coding Schemes

Table B-1 lists the possible modulation and coding methods used for direct sequence spread spectrum (DSSS) and orthogonal frequency-division multiplexing (OFDM) for 802.11b/g and 802.11a wireless LANs.

Table B-2 lists the possible modulation coding schemes (MCS) used in 802.11n wireless LANs. The resulting data rates also vary according to the number of spatial streams in use (1 to 4), the guard interval (800 or 400 ns), and the channel width (20 or 40 MHz).
