Glossary
When one access point is connected to a wired network and supports a set of wireless stations, it
is referred to as a basic service set (BSS). An extended service set (ESS) is created by combining
two or more BSSs.
Ad hoc Mode
Ad hoc mode is a Wireless Networking Framework
each other. It is useful for quickly establishing a network in situations where formal infrastructure
is not required.
Ad hoc mode is also referred to as peer-to-peer mode or an independent basic service set
(IBSS).
AES
The Advanced Encryption Standard (AES) is a symmetric 128-bit block data encryption technique
developed to replace DES encryption. AES works at multiple network layers simultaneously.

Basic Rate Set
The basic rate set defines the transmission rates that are mandatory for any station wanting to
join this wireless network. All stations must be able to receive data at the rates listed in this set.
Beacon
Beacon frames provide the "heartbeat" of a WLAN, announcing the existence of the network,
and enabling stations to establish and maintain communications in an orderly fashion. It carries
the following information (some of which is optional):
• The Timestamp is used by stations to update their local clock, enabling synchronization
among all associated stations.
• The Beacon interval defines the amount of time between transmitting beacon frames. Before
entering power save mode, a station needs the beacon interval to know when to wake up to
receive the beacon.
• The Capability Information lists requirements of stations that want to join the WLAN. For
example, it indicates that all stations must use WEP.
• The Service Set Identifier (SSID).
• The Basic Rate Set
• The optional Parameter Sets indicates features of the specific signaling methods in use (such
as frequency hopping spread spectrum, direct sequence spread spectrum, etc.).
• The optional Traffic Indication Map (TIM) identifies stations, using power saving mode, that
have data frames queued for them.
Bridge
A connection between two local area networks (LANs) using the same protocol, such as Ethernet
or IEEE 802.1x.
