	Glossary of Terms
802.11	The IEEE standard that specifies Wireless LAN Medium Access Control (MAC) and Physical
	Layer (PHY) specifications.
802.11b	The IEEE standard that specifies Higher-Speed Physical Layer Extension in the 2.4 GHz
	Band for 5.5 and 11 megabit per second wireless LANs.
802.3	The IEEE standard that specifies carrier sense media access control and physical layer
	specifications for Ethernet LANs.
Access Control	The prevention of unauthorized usage of resources.
Access Point	Any entity that has station functionality and provides access to the distribution services, via
(AP)	the wireless medium (WM) for associated stations.
Ad-hoc	An Ad-hoc wireless LAN is a group of computers each with wireless adapters connected as an
	independent wireless LAN.
Advanced	Advanced analog mobile service. Uses a 50 MHz segment of the 800 MHz band to provide
Mobile Phone	832 analog channels. Two service providers are each assigned one half of the channels in each
Service (AMPS)	service area. Analog cellular systems that are similar to AMPs but not compatible include
	Total Access Communications System (TACS) in the United Kingdom, China and other
	countries, and Nordic Mobile Telephone (NMT) in the Scandinavian countries.
Authentication	The service used to establish the identity of one station as a member of the set of stations
	authorized to associate with another station.
Authenticity	Proof that the information came from the person or location that reportedly sent it. One
	example of authenticating software is through digital signatures.
Back Door	A deliberately planned security breach in a program. Back doors allow special access to a
	computer or program. Sometimes back doors can be exploited and allow a cracker
	unauthorized access to data.
Backbone	A high-speed line or series of connections that forms a major pathway within a network.
Bandwidth	This is the capacity on a link usually measured in bits-per-second (bps).
Base Station	In mobile telecommunications, a base station is the central radio transmitter/receiver that
	maintains communication with the mobile radio telephone sets within its range. In cellular
	and personal communications applications, each cell or micro-cell has its own base station;
	each base station in turn is interconnected with other cells’ base stations.
Bit	(Binary Digit) – A single digit number in base-2, in other words, either a one or a zero. The
	smallest unit of computerized data.
Broadband	Refers to telecommunication that provides multiple channels of data over a single
	communications medium.
BSS	Basic Service Set. An Access Point associated with several wireless stations.
Byte	A set of bits that represent a single character. There are 8 bits in a byte.
