2.4 GHz Frequence Band– IEEE 802.11g

• provides higher data rates at 2.4 GHz

• similar speeds as 802.11a

• backward compatible with 802.11b

• modulation

  • BPSK (Binary Phase Shift Keying) ? 1 Mbps
  • QPSK (differential Quaternary Phase Shift Keying) ? 2 Mbps
  • CCK (Complementary Code Keying) ? 5.5 Mbps, 11 Mbps
  • OFDM (Orthogonal Frequency Devision Multiplexing) ? 12 – 54 Mbps

• same modulation as 802.11a (OFDM)

• Draft-Status (3.0)
