ERMINOLOGY
Preamble Type – Some Access Points and Client card drivers have
a radio setting for "Short" RF Preamble. If all the Clients and
Access Points in your wireless network have this feature, then
enabling it can boost your throughput. However, if a radio does
not support this feature, then it will not be able to communicate
with any other radios that have this set to "Short."
Infrastructure – An integrated wireless and wired LAN is called
an Infrastructure configuration.
Management Frame – Control frame for establishing a link
between an access point and a client station. It includes Beacon,
Probe, Authentication, and Association frames.
MSDUs – MAC Service Data Units.
MMPDUs – MAC Management Protocol Data Units.
Roaming – A wireless LAN mobile user moves around an ESS and
maintains a continuous connection to the Infrastructure network.
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.
USB – The Universal Serial Bus allows complete Plug and Play
connection of peripheral devices to a computer.
WEP – "Wired Equivalent Privacy" is based on the use of 64-bit or
128-bit keys and the popular RC4 encryption algorithm. Wireless
devices without a valid WEP key are excluded from network
traffic.
