The 802.11g Standard

• 802.11g standard ratified in June 2003• Operates in the same 2.4-GHz band as

802.11bUses the same three nonoverlapping channels

• Full backward compatibility with 802.11bConceptually similar to Ethernet and fast Ethernet

• Uses OFDM for 802.11g data rates, DSSS for 802.11b data rates

Employs various modulation schemes for a variety of data rates54, 48, 36, 24, 18, 12, 9, and 6 Mbps via OFDM11, 5.5, 2, and 1 Mbps via DSSS
