Infrastructure
An integrated wireless and wired LAN is called an Infrastructure
configuration.
Preamble Type
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 by the IEEE 802.11b
(High-Rate) standard and not by the original IEEE 802.11. That
means that stations using Short-Preamble cannot communicate with
stations implementing the original version of the protocol.
PSDU
Physical Layer Convergence Protocol (PLCP) Service Data Unit.
Roaming
A function that allows mobile devices to move from 1 cell to another
in the ESS, while maintaining network connectivity.
RTS Threshold
Defines the packet size threshold. Beyond this threshold the RTS/CTS
mechanism will NOT be enabled.
WEP
Wired Equivalent Privacy. An encryption scheme used to protect
wireless data communication. Enabling the WEP prevents other
stations without the same WEP key from accessing the AP.
