Preamble type. Preamble is a sequence of bits
transmitted at 1Mbps that allows the PHY circuitry to reach steady-state
demodulation and synchronization of bit clock and frame start. Two different
preambles and headers are defined: the mandatory supported Long Preamble and
header, which interoperates with the 1 Mbit/s and 2 Mbit/s DSSS specification (as
described in IEEE Std 802.11), and an optional Short Preamble and header (as
described in IEEE Std 802.11b). At the receiver, the Preamble and header are
processed to aid in demodulation and delivery of the PSDU. The Short Preamble and
header may be used to minimize overhead and, thus, maximize the network data
throughput. However, the Short Preamble is supported only from the IEEE 802.11b
(High- Rate) standard and not from the original IEEE 802.11. That means that stations
using Short-Preamble cannot communicate with stations implementing the original
version of the protocol.
