Appendix C Glossary
Access Point - An internetworking device that seamlessly connects wired and wireless networks
together.
Ad-Hoc - An Ad-Hoc wireless LAN is a group of computers each with wireless adapters,
connected as an independent wireless LAN.
Backbone - The core infrastructure of a network. The portion of the network that transports
information from one central location to another central location where it is off-loaded
onto a local system.
Base Station - In mobile telecommunication, a base station is the central radio transmitter/
receiver that maintains communication with the mobile radio telephone sets within range.
In cellular and personal communications applications, each cell or microcell has its own
base station; each base station in turn is interconnected with other cells’ base.
BSS - Stands for “Basic Service Set.” An Access Point associated with several wireless
stations.
ESS - Stands for “Extended Service Set.” More than one BSS can be configured as an
Extended Service Set. An ESS is basically a roaming domain.
Ethernet - A popular local area data communications network, originally developed by Xerox
Corp., which accepts transmission from computers and terminals. Ethernet operates on
10 Mbps baseband transmission over shielded coaxial cable or over shielded twisted pair
telephone wire.
Infrastructure - An integrated wireless and wired LAN is called an Infrastructure configuration.
PCMCIA - Personal Computer Memory Card International Association, which develops
standards for PC cards, formerly known as PCMCIA cards, are available in three “types”
which are about the same length and width as credit cards, but range in thickness from
3.3 mm (Type I) to 5.0 mm (Type II) to 10.5 mm (Type III). These cards can be used
for many functions, including memory storage, as landline modems and as wireless
LAN.
Roaming - A function that one can travel with his mobile end system (wireless LAN mobile
station, for example) through the territory of a domain (an ESS, for example) while
continuously connecting to the infrastructure.
RTS Threshold – Transmitters contending for the medium may not hear each other. RTS/CTS
mechanism can solve this “ Hidden Node Problem”.
