Appendix I: Glossary
802.1x - The standard for wireless LAN authentication used between an AP and a client. 802.1x with EAP will initiate
key handling.
Ad-Hoc Network - The wireless network based on a peer-to-peer communications session. Also referred to as AdHoc.
Access Point - Access points are stations in a wireless LAN that are connected to an Ethernet hub or server. Users
can roam within the range of access points and their wireless device connections are passed from one access point to
the next.
Authentication - Authentication refers to the verification of a transmitted message's integrity.
Beacon - In wireless networking, a beacon is a packet sent by a connected device to inform other devices of its
presence and readiness.
Beacon interval - When a wirelessly networked device sends a beacon, it includes with it a beacon interval, which
specifies the period of time before it will send the beacon again. The interval tells receiving devices on the network
how long they can wait in low-power mode before waking up to handle the beacon. Network managers can adjust the
beacon interval, usually measured in milliseconds (ms) or its equivalent, kilo microseconds (Kmsec).
BSS - Basic Service Set. When a WLAN is operating in infrastructure mode, each access point and its connected
devices are called the Basic Service Set.
BSSID - The unique identifier for an access point in a BSS network. See SSID for more details.
DHCP - DHCP (Dynamic Host Configuration Protocol) software automatically assigns IP addresses to client stations
logging onto a TCP/IP network, which eliminates the need to manually assign permanent IP addresses.
DSSS (Direct Sequence Spread Spectrum) - Method of spreading a wireless signal into wide frequency bandwidth.
Dynamic IP Address - An IP address that is automatically assigned to a client station in a TCP/IP network, typically by
a DHCP server.
DNS (Domain Name System): System used to map readable machine names into IP addresses
DTIM - DTIM (Delivery Traffic Indication Message) provides client stations with information on the next opportunity to
monitor for broadcast or multicast messages.
DTIM interval - A DTIM interval, also known as a Data Beacon Rate, is the frequency at which an access point's
beacon will include a DTIM. This frequency is usually measured in milliseconds (ms) or its equivalent, kilo
microseconds (Kmsec).
ESS - Extended Service Set. ESS is the collective term for two or more BSSs that use the same switch in a LAN.
ESSID - Extended Service Set Identifier. An ESSID is the unique identifier for an ESS. See SSID for more details.
Filter - Filters are schemes, which only allow specified data to be transmitted. For example, the router can filter
specific IP addresses so that users cannot connect to those addresses.
Firmware: Programming inserted into programmable read-only memory, thus becoming a permanent part of a
computing device.
Fragmentation - Refers to the breaking up of data packets during transmission.
Gateway
– Is the place where two or more networks connect
IBSS - Independent Basic Service Set. See ad-hoc network
