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 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 or more 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.

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.

Any changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.

Note: The manufacturer is not responsible for any Radio or TV interference caused by
unauthorized modifications to this equipment. Such modifications could void the
user’s authority to operate the equipment.

Federal Communication Commission (FCC) Radiation Expos ure
Statement

This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. End users must follow the specific operating instructions
for satisfying RF exposure compliance. This transmitter must not be co-located or
operating in conjunction with any other antenna or transmitter. This equipment has
been SAR-evaluated for use in hand. SAR measurements are based on a 50mm spacing
from the body and that compliance is achieved at that distance.

RED Compliance Statement

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.

RF Exposure Information (SAR)

This device meets the government’s requirements for exposure to radio waves. This
device is designed and manufactured not to exceed the emission limits for exposure to
radio frequency (RF) energy set by the Federal Communications Commission of the
U.S. Government.

The exposure standard for wireless device employs a unit of measurement known as
the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg.
*Tests for SAR are conducted using standard operating positions accepted by the FCC
with the device transmitting at its highest certified power level in all tested frequency
bands. Although the SAR is determined at the highest certified power level, the actual
SAR level of the device while operating can be well below the maximum value. This
is because the device is designed to operate at multiple power levels so as to use only
the poser required to reach the network. In general, the closer you are to a wireless
base station antenna, the lower the power output.

SAR compliance has been established in the host product(s) (laptop computers),
tested at 50mm separation distance to the human body, and tested with USB slot
configurations including Horizontal-UP, Horizontal-Down, Vertical-Front,
Vertical-Back, Tip. This device can be used in host product(s) with substantially similar
physical dimensions, construction, and electrical and RF characteristics.

The highest SAR value, tested per FCC RF exposure guidelines for USB dongle, as
described in this user guide, is 1.19 W/kg. The FCC has granted an Equipment
Authorization for this device with all reported SAR levels evaluated as in compliance
with the FCC RF exposure guidelines. SAR information on this device is on file with
the FCC and can be found under the Display Grant section of
www.fcc.gov/oet/ea/fccid after searching on FCC ID: NDD9578221212.
This USB dongle transmitter is approved for use in typical laptop computers. To
comply with FCC RF exposure requirements, this USB dongle should not be used in
other devices or certain laptop and tablet computer configurations where the USB
connectors on the host computer are unable to provide or ensure the necessary
operating configurations intended for the device and its users or bystanders to satisfy
RF exposure compliance requirements. This USB dongle should be installed and
operated with minimum distance 50mm between the radiator & your body.

2-6 Establish a Secure Connection with AP by WPS

Wi-Fi Protected Setup (WPS) is the latest wire less network technology
which make s wireless network setup be come very simple. If you have
WPS-enabled wireless access point, a nd you want to establish a secure
connection to it, you do n’t have to configure the wireless access point and
setup data e ncryption by yourself. All you have to do is t o go to the WPS
setup page of this wireless adapter, click a button, a nd then press a
specific bu tton or enter a set of 8-digit code on the wireless access point
you wish to establ ish a secur e con ne ct io n - just three simple steps!

For older wireless acces s points, it’s possible to perform a firmware
upgrade to become a WPS-enabled access point. Since they may not have
a hardware button to press for WPS setup, you can u se an alternati ve
WPS setup method - input the pin co de. Every WPS-compatible wireless
network ada pter support pin code conf iguration method; you can jus t
input the co de to wireless a ccess point, a nd the wireless access point a nd
wireless network adapte r will do the rest for you.

This wireless network adapter is compatible with WPS. To use this
function, the wireless a ccess point y ou wish to connect to must support
WPS functio n too. Now, please follow the following instructions to
establish secure connection between WPS-enabled wireless access point
and your wireless network adapter.

This wireless network adapter supports 2 kinds of WPS: PIN code and
Push-Button.

Follow the following instructions to setup WPS:

1. Right-click Realtek conf iguration utility icon, a nd click ‘Open Config

Utility’.

34

2. Click ‘Wi-Fi Protect Setup’ menu.

3. You can use PIN code or Push-Button configuration, and

WPS-compatible wireless access point must use the same type of WPS.
For instructi ons on setup each type of WPS, see next 2 chapters for
detailed instructions.

4-3 Glossary

1. What is the IEEE 8 02.11g standard?

802.11g is the new IEEE standard for high-spee d wireless LA N
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 hom e, office and public networks.

802.11g defines the use of the same OFDM modulation technique
specified i n IEEE 802.11a for the 5 GHz freque ncy band and applies
it in the same 2.4 GHz frequency band as IEEE 802.11b. The

802.1 1 g sta n dar d re q uir es ba c kwa r d com pa tib il ity with 8 02. 11b.
The standar d 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 (manda tory speeds), and 18,
36, 48 and 54 Mbps (optional speeds). The ERP includes the
modulation schemes found in 802.11b incl uding CCK for 1 1 and

5.5 Mbps an d Barker code modulation for 2 and 1 Mbps.

B. A protection mechanism called RTS/CTS that governs how

802.1 1 g de vic e s and 80 2. 11b devic es in ter op er at e.

2. What is the IEEE 8 02.11b standard?

The IEEE 802.11b Wireless LAN standard subcommittee , which
formulates the standard f or the industr y. 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 f ollowing IEE E 802.11 functions:

 CSMA/CA plus Acknowledge Protocol
 Multi-Channel Roaming
 Automatic R ate Selection
 RTS/CTS Feature
 Fragmentation
 Power Mana gement

4. What is Ad-hoc?

An Ad-hoc integrated wireless LAN is a group of computers, each
has a Wireless LAN adapter, Connecte d as an independent wireless
LAN. Ad hoc wireless LAN is a pplicable at a departmental scale for

53

a branch or SOHO operation.

5. What is Infrastructu re?

An integrated wireless and wireless and wired LAN is called an
Infrastructure configuration. Infra structure is a pplicable to enterprise
scale for wireless access to central database, or wireless application
for mobile w orkers.

6. What is BSS ID?

A specific Ad hoc LAN is called a Basic Service Set (BSS).
Computers in a BSS must be configured w ith 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 quic kly 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 specific a tion might be officially released by early 2003.

9. What is AES?

AES (Advanced Encryption St andard), a chip-based security, has
been devel oped to ensure the highest degr ee of security and
authenticity for digita l information, wherever an d however
communicated or stored, while making more effi cient 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 repl aci ng W EP 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, W ireless products ca n work with Netware, Windows
2000, or other LAN operating systems to support printer or file
sharing.

11. Would the info rmation be int ercepted while transmitting on air?

WLAN features two-fold pr otection in security. On the hardware
side, as with Direct Sequence Spread Spectrum technology, it has
the inheren t security feature of scrambling. On the software side,
WLAN series offer the encryption function (WEP) to enhance
security a nd Access Control. Users can set i t up depending upon
their needs.

54

12. What is DSSS? What is FHSS? And what are their differences?

Frequency-hoppi ng spr ea d-spectrum (FHSS) uses a narrowband
carrier that changes fre quency in a pattern that is k nown to both
transmitte r and receive r. Properly synchronized, the ne t effect is to
maintain a s ingle logical channel. To an unintended receiver, FHSS
appears to be short-duration impulse noise. Direct-sequence
spread-spectrum (DSSS) gener ates a redun dant 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 recove red. 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 r eceiver, DSSS app e ars 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 syst ems. It is designed to trade off
bandwidth e fficiency for reliability, integrity, and security. In other
words, m or e 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 rece iver knows the
parameters of the spread-spectrum signal being broadcast. If a
receiver is not tuned to the right freque ncy, a spread –spectrum
signal looks like bac k gro u nd noi se. T he re a re two m a in alter na ti ve s,
Direct Sequence Spread Spectrum (DS SS) and Frequenc y Hopping
Spread Spectrum (FHSS) .

14. What is WPS?

WPS stands f or Wi-Fi Protec ted Setup. It provides a simple way to
establish unencrypted or encrypted connections between wireless
clients and a c cess point automatically. User can press a software or
hardware button to activate WPS function, and WPS-compatible
wireless cl ients and access point will establish connection by
themselve s. There are two types of WPS: PBC (Push-Button
Configuration) and PIN code.
