Appendix B: Glossary

• 802.11b - The 802.11b standard specifies a wireless 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 secu rity. 802.11b networks a re also referred to as Wi-Fi
networks.

• 802.11g - specification for wireless networking at 54 Mbps using direct-
sequen ce spread-spectrum (DSSS) technology, using OFDM modulati on
and operating in the unlicensed radio spectrum at 2.4GHz, and
backward compatibility with IEEE 802.11b devices, and WEP en cryption
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 mo de is al so ref erred to a s an In dependent Ba sic Servi ce
Set (IBSS) or as peer-to-peer mode, and is useful at a departmental
scale o r SO HO o pe r ation.

• 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.

25

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 dev ices, ea ch 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 t o
a wired netwo rk is ref erred to as a Basic Service S et (BSS). A set of two
or more BS S in a si ngle networ k is referred to as an Exten ded 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 militar y 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 wireles s network name.

26

• WEP (Wired Equivalent Privacy) - A data pri vacy mecha nism based on
a 64 -bit o r 128-bit o r 152-bit shared key algorithm, as described in the
IEEE 8 02. 11 s ta nd ard .

• 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
netw or k ser vi ng us e rs ar e lim it ed in a lo c a l ar ea.

• 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 s erver.
