Parameter
Description
Ad Hoc Default Channel
Select the number of the radio channel used for the Ad Hoc
networking. The channel of all the wireless stations in the Ad Hoc
network should be the same. The parameter is not active in the
infrastructure operation mode.
Note: The Infrastructure operation mode requires the presence of
an 802.11 Access Point. All communication is done via the
Access Point.
Encryption Algorithm
The parameter is only active in the Ad Hoc operation mode. There
are three kinds of encrypion algorithm supported by the card
including WEP, TKIP and AES.
WEP is an authentication algorithm, which protects authorized
Wireless LAN users against eavesdropping. WEP has been found
that it has some security problems. TKIP is a temporary quick-fix
method defined in IEEE 802.11i standard to quickly overcome the
inherent weaknesses in WEP security. AES has been developed
to ensure the highest degree of security and authenticity for
digital information and it is the most advanced solution defined by
IEEE 802.11i for the security in the wireless network.
The security setting must be the the same on the wireless stations
within the network.

Parameter
Description
Preamble Mode
The preamble defines the length of the CRC block for
communication among the wireless stations. There are three
mode including Long, Short and Auto. High network traffic areas
should use the shorter preamble type. If “Auto“ mode is selected,
the card will auto switch the preamble mode depending on the
wireless stations which the card is connecting to.
Note that the parameter is only active in the Ad Hoc operation
mode.

4 Troubleshooting
This chapter provides solutions to problems usually encountered during the installation and
operation of the card.
1. 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.
2. What does IEEE 802.11 feature support?
The product supports the following IEEE 802.11 functions:
O
O
O
O
O
O
CSMA/CA plus Acknowledge Protocol
Multi-Channel Roaming
Automatic Rate Selection
RTS/CTS Feature
Fragmentation
Power Management
3. What is Ad-hoc?
An Ad-hoc integrated wireless LAN is a group of computers, each has a Wireless LAN
adapter, Connected as an independent wireless LAN. Ad hoc wireless LAN is
applicable at a departmental scale for a branch or SOHO operation.
4. 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.
5. 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.
6. 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.
7. 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.
16
8. 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.
9. What is IEEE 802.1x?
802.1x, an IEEE standard that provides an authentication framework for 802-based
LANs. 802.1x will let wireless LANs scale by allowing centralized authentication of
wireless users or stations. Based on the 802.1x framework, any wireless stations try to
connect to the Access Point or Router should be authenticated by an Authentication
Server.
The Authentication Server identifies the wireless station by a set of user name and
password, only wireless stations provide correct user name and password can connect
to the Access Point or Router and access to the network.

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 their needs.
17
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 spreadspectrum (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).
