3-3 Glossary 1. What is the IEEE 802.11g standard?
802.11g is the new IEEE standard for high-speed wireless LAN
communications that provides for up to 54 Mbps data rate in the 2.4
GHz band. 802.11g is quickly becoming the next mainstream
wireless LAN technology for the home, office and public networks.
802.11g defines the use of the same OFDM modulation technique
specified in IEEE 802.11a for the 5 GHz frequency band and applies
it in the same 2.4 GHz frequency band as IEEE 802.11b. The
802.11g standard requires backward compatibility with 802.11b.
The standard specifically calls for:
A. A new physical layer for the 802.11 Medium Access Control
(MAC) in the 2.4 GHz frequency band, known as the extended
rate PHY (ERP). The ERP adds OFDM as a mandatory new
coding scheme for 6, 12 and 24 Mbps (mandatory speeds), and 18,
36, 48 and 54 Mbps (optional speeds). The ERP includes the
modulation schemes found in 802.11b including CCK for 11 and
5.5 Mbps and Barker code modulation for 2 and 1 Mbps.
B. A protection mechanism called RTS/CTS that governs how
802.11g devices and 802.11b devices interoperate.
2. What is the IEEE 802.11b standard?
The IEEE 802.11b Wireless LAN standard subcommittee, which
formulates the standard for the industry. The objective is to enable
wireless LAN hardware from different manufactures to
communicate.
3. What does IEEE 802.11 feature support?
The product supports the following IEEE 802.11 functions:
z

4. What is Ad-hoc?
An Ad-hoc integrated wireless LAN is a group of computers, each
has a Wireless LAN card, Connected as an independent wireless
LAN. Ad hoc wireless LAN is applicable at a departmental scale for
46
a branch or SOHO operation.
5. What is Infrastructure?
An integrated wireless and wireless and wired LAN is called an
Infrastructure configuration. Infrastructure is applicable to enterprise
scale for wireless access to central database, or wireless application
for mobile workers.
6. What is BSS ID?
A specific Ad hoc LAN is called a Basic Service Set (BSS).
Computers in a BSS must be configured with the same BSS ID.
7. What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based
on a 40 bit shared key algorithm, as described in the IEEE 802 .11
standard.
8. What is TKIP?
TKIP is a quick-fix method to quickly overcome the inherent
weaknesses in WEP security, especially the reuse of encryption keys.
TKIP is involved in the IEEE 802.11i WLAN security standard, and
the specification might be officially released by early 2003.
9. What is AES?
AES (Advanced Encryption Standard), a chip-based security, has
been developed to ensure the highest degree of security and
authenticity for digital information, wherever and however
communicated or stored, while making more efficient use of
hardware and/or software than previous encryption standards. It is
also included in IEEE 802.11i standard. Compare with AES, TKIP is
a temporary protocol for replacing WEP security until manufacturers
implement AES at the hardware level.
10. Can Wireless products support printer sharing?
Wireless products perform the same function as LAN products.
Therefore, Wireless products can work with Netware, Windows
2000, or other LAN operating systems to support printer or file
sharing.
11. Would the information be intercepted while transmitting on air?
WLAN features two-fold protection in security. On the hardware
side, as with Direct Sequence Spread Spectrum technology, it has
the inherent security feature of scrambling. On the software side,
WLAN series offer the encryption function (WEP) to enhance
security and Access Control. Users can set it up depending upon
47
their needs.
12. What is DSSS? What is FHSS? And what are their differences?
Frequency-hopping spread-spectrum (FHSS) uses a narrowband
carrier that changes frequency in a pattern that is known to both
transmitter and receiver. Properly synchronized, the net effect is to
maintain a single logical channel. To an unintended receiver, FHSS
appears to be short-duration impulse noise. Direct-sequence
spread-spectrum (DSSS) generates a redundant bit pattern for each
bit to be transmitted. This bit pattern is called a chip (or chipping
code). The longer the chip is, the greater the probability that the
original data can be recovered. Even if one or more bits in the chip
are damaged during transmission, statistical techniques embedded in
the radio 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.
13. What is Spread Spectrum?
Spread Spectrum technology is a wideband radio frequency
technique developed by the military for use in reliable, secure,
mission-critical communication 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).
14. What is WPS?
WPS stands for Wi-Fi Protected Setup. It provides a simple way to
establish unencrypted or encrypted connections between wireless
clients and access point automatically. User can press a software or
hardware button to activate WPS function, and WPS-compatible
wireless clients and access point will establish connection by
themselves. There are two types of WPS: PBC (Push-Button
Configuration) and PIN code.
