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 stations 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 are including TKIP and AES.   Note that this option is only available for Windows XP.   10   Download from Www.Somanuals.com. All Manuals Search And Download.   Parameter   Description   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”   range) or 5-digit ASCII characters (including “a-z” and “0-9”) as   the encryption keys. For example: “0123456aef“ or “test1”.   128-bit – Input 26-digit Hex values (in the “A-F”, “a-f” and “0-9”   range) or 13-digit ASCII characters (including “a-z” and “0-9”) as   the encryption keys. For example:   “01234567890123456789abcdef“ or “administrator”.   11   Download from Www.Somanuals.com.

The technical components of WPA   include Temporal Key Integrity Protocol (TKIP) for dynamic key exchange, and 802.1x for   authentication.   There are two types of WPA security: WPA-PSK (no server) and WPA (with server). WPA requires a   Radius Server to complete authentication among wireless stations and Access Points. Typically, this   mode is used in an enterprise environment. WPA-PSK uses a so-called pre-shared key as the security   key. A pre-shared key is a password that every wireless station must use to access the network.   Typically, this mode will be used in a home environment.   To enable the WPA function in Windows XP, the following software systems are required:   1. Windows XP Service Pack 1 with Windows XP Support Patch for Wi-Fi Protected Access program   in addition.   2. Configure the card using Wireless built-in utility (Wireless Zero Configuration).   z Note: When using the Wireless Utility there are two function selections when you open the   execute the program. You can select to use the XP’s built-in utility with full WPA function. If   “Use XP Wireless Zero Configuration” is selected, you can only configure the advance   setting or check the link status and statistics from the “RaConfig” utility.   1. From here, right click the   icon to select “View   Available Wireless   Networks”.   2. Press “Advanced” button   from “Wireless Network   Connection”.   12   Download from Www.Somanuals.com.

Press the “Configure” button to configure the   WPA function for the current network.   Note: Uncheck “Use Windows to Configure my wireless network settings”, the “RaConfig” utility will be   enabled again.   Parameter   Network Authentication   Description   Open –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 – This mode is for enterprise with an authentication server   (Radius Server), WPA-enabled access point, and a WPA-enabled   client. Once WPA is enabled, all clients and access points on the   network must be WPA-enabled in order to access the network.   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 PC on the wireless 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.   13   Download from Www.Somanuals.com. All Manuals Search And Download.   Parameter   Description   Data Encryption   WEP – In WPA or WPA-PSK mode, WEP is also able to be the   encryption method for the transmission data.   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.   3.3   Link Status   From the “Link Status” option, you can view all the information of the network you are connecting to.   You can use this tool in while at the same time repositioning the Hi-Gain antenna to find the optimal   location for antenna placement.   Parameter   Status   Description   Display the SSID and MAC ID of the network the card is   connecting to.   Current Channel   Display the number of the radio channel and the frequency used   14   Download from Www.Somanuals.com.

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:   z z z z z z 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 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.   20   Download from Www.Somanuals.com. All Manuals Search And Download.   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 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.   21   Download from Www.Somanuals.com. All Manuals Search And Download.   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 Hi-Gain and dBi?   Hi-Gain is Hawking Technologies high performance wireless distance extending product line. It   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.   15. 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) while the clients (desktop or laptops) that use the   directional antennas (concentrated narrow wireless signal) to create a stronger link directly to   the access point.   16. How do I get an Optimal Wireless Connection with the HWC54D?   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.   22   Download from Www.Somanuals.com.
