Appendix B --- About Wireless LANs

Overview

Wireless networks have their own terms and jargon. You should understand these terms in order to
configure and operate a wireless LAN.

Wireless LAN Terminology

Modes

Wireless LANs can work in either of two modes:

•

Ad-hoc

•

Infrastructure

Ad-hoc Mode

Ad-hoc mode does not require an access point or a wired (Ethernet) LAN. Wireless stations, e.g.,
notebook PCs with wireless cards, communicate directly with each other.

Infrastructure Mode

In Infrastructure Mode, one or more access points are used to connect wireless stations, e.g.,
notebook PCs with wireless cards, to a wired (Ethernet) LAN. The wireless stations can then access
all LAN resources.

Note—

Access points can only function in Infrastructure Mode, and can communicate only with

wireless stations that are set to Infrastructure Mode.

SSID/ESSID

BSS/SSID

A group of wireless stations and a single access point, all using the same ID (SSID), form a Basic Service
Set (BSS).
Using the same SSID is essential. Devices with different SSIDs are unable to communicate with each
other.

ESS/ESSID

A group of wireless stations, and multiple access points, all using the same ID (ESSID), form an
Extended Service Set (ESS).
