Appendix B: Glossary
•
802.11b – The 802.11b standard specifies a wireless networking at 11 Mbps using direct-sequence spreadspectrum (DSSS) technology and operating in the unlicensed radio spectrum at 2.4GHz, and WEP encryption
for security. 802.11b networks are also referred to as Wi-Fi networks.
•
802.11g – specification for wireless networking at 54 Mbps using direct-sequence spread-spectrum (DSSS)
technology, using OFDM modulation and operating in the unlicensed radio spectrum at 2.4GHz, and backward
compatibility with IEEE 802.11b devices, and WEP encryption for security.
•
Ad-hoc Network – An ad-hoc network is a group of computers, each with a wireless adapter, connected as an
independent 802.11 wireless LAN. Ad-hoc wireless computers operate on a peer-to-peer basis, communicating
directly with each other without the use of an access point. Ad-hoc mode is also referred to as an Independent
Basic Service Set (IBSS) or as peer-to-peer mode, and is useful at a departmental scale or SOHO operation.
•
DSSS (Direct-Sequence Spread Spectrum) – DSSS generates a redundant bit pattern for all data transmitted.
This bit pattern is called a chip (or chipping code). Even if one or more bits in the chip are damaged during
transmission, statistical techniques embedded in the receiver can recover the original data without the
need for retransmission. To an unintended receiver, DSSS appears as low power wideband noise and is
rejected (ignored) by most narrowband receivers. However, to an intended receiver (i.e. another wireless
LAN endpoint), the DSSS signal is recognized as the only valid signal, and interference is inherently rejected
(ignored).
•
FHSS (Frequency Hopping Spread Spectrum) – FHSS continuously changes (hops) the carrier frequency of a
conventional carrier several times per second according to a pseudo-random set of channels. Because a fixed
frequency is not used, and only the transmitter and receiver know the hop patterns, interception of FHSS is
extremely difficult.
•
Infrastructure Network – An infrastructure network is a group of computers or other devices, each with
a wireless adapter, connected as an 802.11 wireless LAN. In infrastructure mode, the wireless devices
communicate with each other and to a wired network by first going through an access point. An infrastructure
wireless network connected to a wired network is referred to as a Basic Service Set (BSS). A set of two or more
BSS in a single network is referred to as an Extended Service Set (ESS). Infrastructure mode is useful at a
corporation scale, or when it is necessary to connect the wired and wireless networks.
•
Spread Spectrum – Spread Spectrum technology is a wideband radio frequency technique developed by
the military for use in reliable, secure, mission-critical communications systems. It is designed to trade off
bandwidth efficiency for reliability, integrity, and security. In other words, more bandwidth is consumed
than in the case of narrowband transmission, but the trade off produces a signal that is, in effect, louder and
thus easier to detect, provided that the receiver knows the parameters of the spread-spectrum signal being
broadcast. If a receiver is not tuned to the right frequency, a spread-spectrum signal looks like background
noise. There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping
Spread Spectrum (FHSS).
•
SSID – A Service Set Identification is a thirty-two character (maximum) alphanumeric key identifying a
wireless local area network. For the wireless devices in a network to communicate with each other, all devices
must be configured with the same SSID. This is typically the configuration parameter for a wireless PC card. It
corresponds to the ESSID in the wireless Access Point and to the wireless network name.
•
WEP (Wired Equivalent Privacy) – A data privacy mechanism based on a 64-bit or 128-bit or 152-bit shared
key algorithm, as described in the IEEE 802.11 standard.
•
Wi-Fi – A trade name for the 802.11b wireless networking standard, given by the Wireless Ethernet
Compatibility Alliance (WECA, see http://www.wi-fi.net), an industry standards group promoting
interoperability among 802.11b devices.
•
WLAN (Wireless Local Area Network) – A group of computers and associated devices communicate with each
other wirelessly, which network serving users are limited in a local area.
•
WPA (Wi-Fi Protected Access) – A wireless security protocol use TKIP (Temporal Key Integrity Protocol)
encryption, which can be used in conjunction with a RADIUS server.
