Appendix B: Glossary
¾802.11b - 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.
¾802.11g -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.
¾802.11n - 802.11n builds upon previous 802.11 standards by adding MIMO (multiple-input
multiple-output). MIMO uses multiple transmitter and receiver antennas to allow for 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] 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.
¾Ad-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.
¾DSSS - (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).
¾FHSS - (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.
¾Infrastructure 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.
¾Spread Spectrum - Spread Spectrum technology is a wideband radio frequency technique

PW-MN421 Wireless Lite-N USB Module

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).
¾WEP - (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.
¾Wi-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.
¾WLAN - (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.
¾WPA - (Wi-Fi Protected Access) -A wireless security protocol uses TKIP (Temporal Key
Integrity Protocol) encryption, which can be used in conjunction with a RADIUS server.
