GLOSSARY

This appendix provides a glossary of wireless terminology.

802.11

Wireless standards developed by the IEEE that specify an "over-the-air"

 

interface for wireless Local Area Networks. 802.11 is composed of several

 

standards operating in different radio frequencies.

802.11b

802.11b is the international standard for wireless networking that operates in

 

the 2.4 GHz frequency range (2.4 GHz to 2.4835 GHz) and provides a

 

throughput of up to 11 Mbps.

802.11g

802.11g is the international standard for wireless networking that operates in

 

the 2.4 GHz frequency range (2.4 GHz to 2.4835 GHz) and provides a

 

throughput of up to 54 Mbps.

Access Point

An interface between a wireless network and a wired network. Access Points

 

can combine with a distribution system (such as Ethernet) to create multiple

 

radio cells (BSSs) that enable roaming throughout a facility.

Ad-Hoc mode

A wireless network composed of only stations and no Access Point.

Association service

An IEEE 802.11 service that enables the mapping of a wireless station to the

 

distribution system via an Access Point.

Asynchronous

Type of synchronization where there is no defined time relationship between

transmission

transmission of frames.

Authentication

The process a station uses to announce its identify to another station.

 

IEEE 802.11 specifies two forms of authentication: open system and shared

 

key.

Bandwidth

The amount of transmission capacity available on a network at any point in

 

time. Available bandwidth depends on several variables such as the rate of

 

data transmission speed between networked devices, network overhead,

 

number of users, and the type of device used to connect PCs to a network.

Basic Service Set

A set of 802.11-compliant stations that operate as a connected wireless

(BSS)

network.

Bits per second

A measurement of data transmission speed over communication lines based

(bps)

on the number of bits that can be sent or received per second.

BSSID

Basic Service Set Identifier. A 48-bit identifier used by all stations in a BSS in

 

frame headers. Usually a MAC address.

Clear channel

A function that determines the state of the wireless medium in an IEEE

assessment

802.11 network.

Client

Any computer connected to a network that requests services (files, print

 

capability) from another member of the network.

Direct Sequence

Combines a data signal at the sending station with a higher data rate bit

Spread Spectrum

sequence, which many refer to as a “chip sequence” (also known as

(DSSS)

“processing gain”). A high processing gain increases the signal’s resistance

 

to interference. The minimum processing gain that the FCC allows is 10, and

 

most products operate under 20.
