Terminology

The following is a list of terminology used in this document.

Access Point – An internetworking device that seamlessly connects wired and wireless networks.

Ad Hoc – An ad hoc wireless LAN is a group of computers each with LAN adapters, connected as an independent wireless LAN.

BSS – BSS stands for “Basic Service Set.” It is an access point and all the LAN PCs that are associated with it.

CSMA/CA – Carrier Sense Multiple Access with Collision Avoidance.

Data Frame – Packets transmitted/received by the device that carries data. (See Management Frame on the this page.)

ESS – ESS (ESS-ID, SSID) stands for “Extended Service Set.” More than one BSS is configured to become an Extended Service Set. LAN mobile users can roam between different BSSs in an ESS (ESS-ID, SSID).

Ethernet – A popular local area data communications network, which accepts transmissions from computers and terminals. Ethernet operates on a 10 Mbps baseband transmission rate, using shielded coaxial cable or twisted-pair cable.

Fragmentation Threshold – In the 802.11 Standard, the MAC Layer may fragment and reassemble directed MSDUs or MMPDUs. The fragmentation and defragmentation mechanisms allow for fragment re-transmission.

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.
