Appendix C Glossary
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.
Backbone
―
The core infrastructure of a network. The portion of the network transports information from one
central location to another central location where it is unloaded onto a local system.
Bridge
―
An internetworking function that incorporates the lowest 2 layers of the OSI network protocol model.
BSS
―
BSS stands for “Basic Service Set”. It is an Access Point and all the LAN PCs that associated with it.
ESS
―
ESS stands for “Extended Service Set”. More than one BSS is configured to become Extended Service
Set. LAN mobile users can roam between different BSSs in an ESS.
Ethernet
―
A popular local area data communications network, originally developed by Xerox Corp., that
accepts transmission from computers and terminals. Ethernet operates on a 10 Mbps baseband transmission rate,
using a shielded coaxial cable or over shielded twisted pair telephone wire.
Infrastructure
―
An integrated wireless and wired LAN is called an Infrastructure configuration.
Roaming
―
A LAN mobile user moves around an ESS and enjoys 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.
DSSS
―
direct sequence spread spectrum
PLCP
―
physical layer convergence protocol
PPDU
―
PLCP protocol data unit
PSDU
―
PLCP service data unit
Ethernet Mac Address
―
Don’t change it, as this will disable the AP.
Ethernet IP Address and SubMask
―
Please setup them to match your network environment.
For example : If your IP address is 192.168.99.127 and your SubMask is 255.255.255.0. Please set the
IP address of the AP to 192.168.99.xx which will not have conflict with other IP address
and set the SubMask of the AP to 255.255.255.0.
Channel
―
The AP and the with it associated stations will work in this channel. You must set the channel by
consulting Appendix B from violating the Specifications.
Basic Rate
―
the data rate of the AP with the value 1,2,5.5 or 11 Mbps for your selection.
