Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications.
However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
- Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: To assure continued compliance, (example - use only shielded interface
cables when connecting to computer or peripheral devices) any changes or modifications
not expressly approved by the party responsible for compliance could void the user's
authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions:
(1) This device may not cause harmful interference.
(2) This device must accept any interference received, including interference that may
cause undesired operation.
IMPORTANT NOTE:
This module is restricted to mobile configuration. To comply with FCC RF exposure
compliance requirements, the antenna used for this transmitter must be installed to
provide a separation distance of at least 20 cm from all persons and must not be
co-located or operating in conjunction with any other antenna or transmitter. This
transmitter module must not be co-located or operating in conjunction with any other
antenna or transmitter
Industry Canada Statement
Operation is subject to the following two conditions:
1) This device may not cause interference
2) This device must accept any interference, including interference that may cause
undesired operation of the device
This device has been designed to operate with an antenna having a maximum gain of
2.58 dBi. (Antenna gain)
Antenna having a higher gain is strictly prohibited per regulations of Industry Canada.
The required antenna impedance is 50 ohms.

Troubleshooting
This chapter provides solutions to problems usually encountered during the installation
and operation of the adapter.
1. What is the IEEE 802.11g standard？
The IEEE 802.11g 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:
•
•
•
•
•
•
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.
18
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.
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.
19
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.
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.
20
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).
