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 wireless network technology
which makes wireless network setup become very simple. If you have
WPS-enabled wireless access point, and you want to establish a secure
connection to it, you don’t have to configure the wireless access point and
setup data encryption by yourself. All you have to do is to go to the WPS
setup page of this wireless adapter, click a button, and then press a
specific button or enter a set of 8-digit code on the wireless access point
you wish to establish a secure connection - just three simple steps!
For older wireless access 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 use an alternative
WPS setup method - input the pin code. Every WPS-compatible wireless
network adapter support pin code configuration method; you can just
input the code to wireless access point, and the wireless access point and
wireless network adapter will do the rest for you.
This wireless network adapter is compatible with WPS. To use this
function, the wireless access point you wish to connect to must support
WPS function 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 configuration utility icon, and click ‘Open Config
Utility’.
![](/img.php?id=3457078&img=bg2b.png)
35
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 instructions on setup each type of WPS, see next 2 chapters for
detailed instructions.

4-3 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 adapter, Connected as an independent wireless
LAN. Ad hoc wireless LAN is applicable at a departmental scale for
54
a branch or SOHO operation.
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.
55
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.
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 function, and WPS-compatible
wireless clients and access point will establish connection by
themselves. There are two types of WPS: PBC (Push-Button
Configuration) and PIN code.
