Interference Statement
FCC Part 15
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to Part 15 of 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 or more of the following
measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
4. Consult the dealer or an experienced radio technician for help.
FCC Caution
This equipment must be installed and operated in accordance with provided
instructions and a minimum 20 cm spacing must be provided between
computer mounted antenna and person’s body (excluding extremities of hands,
wrist and feet) during wireless modes of operation.
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,
and (2) this device must accept any interference received, including
interference that may cause undesired operation.
Any changes or modifications not expressly approved by the party responsible
for compliance could void the authority to operate equipment.
Federal Communication Commission (FCC) Radiation Exposure
Statement
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. In order to avoid the possibility of exceeding the
FCC radio frequency exposure limits, human proximity to the antenna shall not
be less than 20cm (8 inches) during normal operation.
The antenna(s) used for this transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.
The equipment version marketed in US is restricted to usage of the channels
1-11 only.
For operation within 5.15 ~ 5.25GHz frequency range, it is restricted
to indoor environment.

radio equipment and telecommunication terminal Equipment and the mutual
recognition of their conformity (R&TTE).
The R&TTE Directive repeals and replaces in the directive 98/13/EEC
(Telecommunications Terminal Equipment and Satellite Earth Station
Equipment) As of April 8, 2000.
Safety
This equipment is designed with the utmost care for the safety of those who
install and use it. However, special attention must be paid to the dangers of
electric shock and static electricity when working with electrical equipment. All
guidelines of this and of the computer manufacture must therefore be allowed
at all times to ensure the safe use of the equipment.

5-3 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:






CSMA/CA plus Acknowledge Protocol
Multi-Channel Roaming
Automatic Rate Selection
RTS/CTS Feature
Fragmentation
Power Management
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 a branch or SOHO
operation.
30
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 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
31
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
