MAC Address: Media Access Control Address is a unique hex number
assigned by the manufacturer to any Ethernet networking device, such as a
network adapter, that allows the network to identify it at the hardware level.
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.
