Q: What is the IEEE 802.11g standard?
A: IEEE 802.11g standard specifies data rates of up to 54 Mbps in the 2.45-GHz band. It uses
Orthogonal Frequency Division Multiplexing (OFDM), which is the mandatory provisions have been
made within the standard to make it inherently compatible with the well-established 802.11b standard
at 11 Mbps, which uses Complementary Code Keying (CCK) modulation. Both .11g and .11b can
operate at ranges of up to 300 feet.
