IEEE 802.11 Orthogonal Frequency Division Multiplexing (OFDM) Physical Layer

The IEEE 802.11 Orthogonal Frequency Division Multiplexing (OFDM) Physical layer delivers
up to 54Mbps data rates in the 5GHz band. The OFDM Physical layer, commonly referred
to as 802.11a, will likely become the basis for high-speed wireless LANs as 802.11a products
are first available in late 2001 and early 2002. This section describes the architecture and operation
of 802.11 OFDM.
