Multicasting: Sending data to a group of nodes instead of a single destination.
Multiple Bridge – One of the additional AP operating modes offered by 54Mbps
Access Point, which allows a group of APs that consists of two or more APs to
connect two or more Ethernet networks or Ethernet enabled clients together. The way
that multiple bridge setups is based on the topology of Ad-Hoc mode.
Node: A network junction or connection point, typically a computer or workstation.
Packet: A unit of data routed between an origin and a destination in a network.
PLCP: Physical layer convergence protocol
PPDU: PLCP protocol data unit
Preamble Type: During transmission, the PSDU shall be appended to a PLCP
preamble and header to create the PPDU. Two different preambles and headers are
defined as the mandatory supported long preamble and header which interoperates
with the current 1 and 2 Mbit/s DSSS specification as described in IEEE Std
802.11-1999, and an optional short preamble and header. At the receiver, the PLCP
preamble and header are processed to aid in demodulation and delivery of the PSDU.
The optional short preamble and header is intended for application where maximum
throughput is desired and interoperability with legacy and non-short-preamble capable
equipment is not consideration. That is, it is expected to be used only in networks of
like equipment that can all handle the optional mode. (IEEE 802.11b standard)
PSDU: PLCP service data unit
Roaming: A LAN mobile user moves around an ESS and enjoys a continuous
connection to an Infrastructure network.
RTS: Request To Send. An RS-232 signal sent from the transmitting station to the
receiving station requesting permission to transmit.
RTS Threshold: Transmitters contending for the medium may not be aware of each
other. RTS/CTS mechanism can solve this “Hidden Node Problem”. If the packet size
is smaller than the preset RTS Threshold size, the RTS/CTS mechanism will NOT be
enabled.
SSID: Service Set Identifier, which is a unique name shared among all clients and
nodes in a wireless network. The SSID must be identical for each clients and nodes in
the wireless network.
Subnet Mask: The method used for splitting IP networks into a series of sub-groups,
or subnets. The mask is a binary pattern that is matched up with the IP address to turn
part of the host ID address field into a field for subnets.
TCP/IP: Transmission Control Protocol/ Internet Protocol. The basic communication
language or protocol of the Internet. It can also be used as a communications protocol
in a private network, i.e. intranet or internet. When you are set up with direct access to
the Internet, your computer is provided with a copy of the TCP/IP program just as
