Appendix B - Glossary
Appendix B: Glossary
802.11b - The 802.11b standard specifies a wireless product networking at 11 Mbps using
direct-sequence spread-spectrum (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.
802.11n - 802.11n builds upon previous 802.11 standards by adding MIMO (multiple-input
multiple-output). MIMO uses multiple transmitter and
increased data throughput via spatial multiplexing and increased range by exploiting the
spatial diversity, perhaps through coding schemes like Alamouti coding. The Enhanced
Wireless Consortium (EWC)
[3]
HU
UH was formed to help accelerate the IEEE 802.11n
development process and promote a technology specification for interoperability of
next-generation wireless local area networking (WLAN) products.
HreceiverH antennas to allow for
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 of 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).
20
Appendix B - Glossary
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.
Name and ESSID.

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. To gain access
to a WEP network, you must know the key. The key is a string of characters that you create.
When using WEP, you must determine the level of encryption. The type of encryption
determines the key length. 128-bit encryption requires a longer key than 64-bit encryption.
Keys are defined by entering in a string in HEX (hexadecimal - using characters 0-9, A-F) or
ASCII (American Standard Code for Information Interchange – alphanumeric characters)
format. ASCII format is provided so you can enter a string that is easier to remember. The
ASCII string is converted to HEX for use over the network. Four keys can be defined so that
you can change keys easily.
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.
