Authentication vs. Security
Parameter
Description
Authentication Type
This setting has to be consistent with the wireless networks that
the card intends to connect to. All security keys within a network
must match to allow successful communications.
None – No authentication is needed among the wireless network.
Shared – Only wireless stations using a shared key (WEP Key
identified) are allowed to connecting each other.
WPA-PSK –It is a special mode designed for home and small
business users who do not have access to network authentication
servers. In this mode, known as Pre-Shared Key, the user
manually enters the starting password in their access point or
gateway, as well as in each wireless station in the network. WPA
takes over automatically from that point, keeping unauthorized
users that don't have the matching password from joining the
network, while encrypting the data traveling between authorized
devices. The encryption methods include TKIP and AES. Note
that this option is only available for Windows XP.

Encryption Mode
None – Disable the WEP Data Encryption.
WEP – Enable the WEP Data Encryption. When the item is
selected, you have to continue setting the WEP Encryption keys.
TKIP – TKIP (Temporal Key Integrity Protocol) changes the
temporal key every 10,000 packets (a packet is a kind of message
transmitted over a network.) This insures much greater security
than the standard WEP security.
AES – AES has been developed to ensure the highest degree of
security and authenticity for digital information and it is the most
advanced solution defined by IEEE 802.11i for the security in the
wireless network.
Note: All devices in the network should use the same encryption
method to ensure the communication.
WPA Pre-Shared Key
The WPA-PSK key can be from eight to 64 characters and can be
letters or numbers. This same key must be used on all of the
wireless stations in the network.
WEP Key
The WEP keys are used to encrypt data transmitted in the
wireless network. There are two types of key length: 64-bit and
128-bit. Select the default encryption key from Key 1 to Key 4 by
selected the radio button.
(Key1 ~ Key4)
Fill the text box by following the rules below.
64-bit – Input 10-digit Hex values (in the “A-F”, “a-f” and “0-9”

VI. INDEX
This chapter provides solutions to problems usually encountered during the installation and operation
of the adapter.
1. What is the IEEE 802.11n standard?
802.11n is an IEEE 802.11 wireless network standard that increases transmission speeds from a
traditional 11Mbps (802.11b) to over 100Mbps. Currently, the HWUN1 supports up to 300Mbps.
802.11n can handle legacy 11a, 11b and 11g transmission in a mixed mode or only 11n nodes for
maximum performance. It supports the 2.4GHz and 5GHz frequency bands.
The key to the 802.11n standard is the use of multiple antennas, known as MIMO (Multiple
input/multiple output). MIMO technology enables two data streams, transmitter and receiver, to
be sent simultaneously over longer distances and to impre the overall system performance.
2. What does IEEE 802.11 feature support？
The product supports the following IEEE 802.11 functions:
z
z
z
z
z
z
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.
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.
21
Download from Www.Somanuals.com. All Manuals Search And Download.
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. 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.
10. 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.
11. 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.
12. 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).
13. What is Hi-Gain and dBi?
Hi-Gain is Hawking Technologies’ high performance wireless distance extending product line. It
22
Download from Www.Somanuals.com. All Manuals Search And Download.
encompasses a group of products and technologies used to help solve distance issues
accompanied with WiFi products. A unit of measurement on antenna strength and power is dBi.
The higher the dBi or gain level of an antenna the more powerful it is.
14. What is the difference between directional and omni-directional antennas?
Directional and omni-directional antennas determine the wireless output pattern of antennas. In
standard installations it is normally the wireless access point that uses the omni-directional
antenna (360 degree wireless output) whiles the clients (desktop or laptops) that use the
directional antennas (concentrated narrow wireless signal) to create a stronger link directly to the
access point.
15. How do I get an Optimal Wireless Connection with the HWUN1A?
If pointing the antenna directly at the access point is not providing a sufficient signal connection
then you can try bouncing the signals off walls. Wireless signals can reflect off walls or through
windows to get to their desired location so try different positions to find the best antenna orientation
for your network. Pair the HWUN1A with a Hawking Hi-Gain Wireless Antenna for extended range.
