3.3 “Site Survey”
This screen shows all the Access Points or Adapters nearby when operating in Ad-Hoc
mode.
Click “Re-Scan” to collect the BSSID and Channel information of all the wireless devices
near by.
If you want to connect to any device on the list, double-click the item on the list, and the
adapter will automatically connect to the selected device.
3.4 “Encryption”
Additional security can be achieved by using the WEP (Wired Equivalent Privacy) encryption.
WEP encrypts each frame transmitted from the radio, using one of the keys entered from
this panel.
There are four 10 Hex digit encryption keys value available for the WEP. You can define the
encryption key values of their own choice.
Enable the WEP (Wired Equivalent Privacy) option in order to activate WEP encryption for
transmissions between the stations and the Access Point. WEP is an authentication
algorithm, which protects authorized Wireless LAN users against eavesdropping.

3.5 “Advanced”
There are Preamble Type, Fragmentation Threshold, and RTS/CTS Threshold setting
under this mode.
u
Preamble Type (Short/Long): Preamble is the first subfield of PPDU, which is the
appropriate frame format for transmission to PHY (Physical layer). There are two
options, Short Preamble and Long Preamble. The Short Preamble option improves
throughput performance.
u
u
Fragmentation Threshold: The size at which packets will be fragmented. Choose a
setting within a range of 256 to 2346 bytes.
RTS Threshold: Minimum packet size to require an RTS (Request To Send). For
packets smaller than this threshold, an RTS is not sent and the packet is transmitted
directly to the WLAN. This is the option for the RTS Threshold activation.

Troubleshooting
This section provides solutions to problems usually encountered during the installation and
operation of this Wireless PCMCIA Card. Read the description below to solve your problems.
ü
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.
ü
What does IEEE 802.11 feature support？
The product supports the following IEEE 802.11 functions:
lCSMA/CA plus Acknowledge Protocol
lMulti-Channel Roaming
lAutomatic Rate Selection
lRTS/CTS Feature
lFragmentation
lPower Management
ü
ü
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.
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.
ü
ü
ü
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.
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.
Can Wireless products support printer sharing？
Wireless products perform the same function as LAN products. Therefore, Wireless
products can work with Netware, Windows NT/2000, or other LAN operating systems to
support printer or file sharing.
ü
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.

ü
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.
ü
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).
