This ID prevents the unintentional merging of two co-located WLANs. 12 CONFIGURATION

13 You can specify an SSID for the card so only a device with the same SSID can interconnect to the card. This is a computerto-computer (ad hoc) network; wireless access points are not used.: There are two kinds of network types: Infrastructure requires the presence of an access point or router, and all communication is through the AP/router; and ad hoc, which lets you connect to another wireless card in the WLAN network without an AP/router. If this option is selected, the card will work in Ad Hoc mode. Channel: This setting is only available for Ad Hoc mode. Select the number of the radio channel used for the networking. The channel setting should be the same as the network you are connecting to. Network Authentication: This setting has to be consistent with the wireless networks the card is intended to connect with. Select one of seven options from the drop-down menu. Open System No authentication is needed within the network. Shared Key Only wireless stations using a shared key (WEP Key identified) are allowed to connect to each other. WPA 802.1X WPA provides a scheme of mutual authentication using either IEEE 802.1x/Extensible Authentication Protocol (EAP) authentication or pre-shared key (PSK) technology. It provides a high level of assurance to enterprises, small businesses and home CONFIGURATION 13

14 users that data will remain protected and that only authorized users may access their networks. For enterprises that have already deployed IEEE 802.1x authentication, WPA offers the advantage of leveraging existing authentication databases and infrastructure. WPA-PSK This 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 his access point or gateway, as well as in each of the wireless stations in the network. WPA-PSK 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. WPA X Like WPA, WPA2 supports IEEE 802.1x/EAP authentication or PSK technology. It also includes a new advanced encryption mechanism using the Advanced Encryption Standard (AES), which is required for the corporate or government user. The difference between WPA and WPA2 is that WPA2 provides data encryption via the AES, whereas WPA uses TKIP. WPA2-PSK This is also for home and small business use. The difference between WPA-PSK and WPA2-PSK is that WPA2-PSK provides data encryption via AES, whereas WPA-PSK uses TKIP. WEP 802.1X This is a special mode for using IEEE 802.1x/EAP technology for authentication and WEP keys for data encryption. Data Encryption: Select one of four options from the drop-down menu. NOTE: Options depend on the Network Authentication selection. Disabled Disables WEP Data Encryption. WEP Enables WEP Data Encryption. When this is selected, you need to continue with the setting of the WEP encryption keys. TKIP Temporal Key Integrity Protocol (TKIP) changes the temporal key every 10,000 packets (a packet is a kind of message transmitted over a network.) This ensures much greater security than standard WEP security. AES This has been developed to ensure the highest degree of security and authenticity for digital information. It s the most advanced solution defined by IEEE i for the security in the wireless network. 14 CONFIGURATION

15 Note: All devices in the network should use the same encryption method to ensure the integrity of any communication. ASCII/Passphrase: Select either option and enter in the text field. You must use the same passphrase or WEP key settings for all wireless computers within the network. Network Key: Enter a key to encrypt data transmitted in the wireless network. NOTE: When Passphrase is selected, input a 10-digit hexadecimal value (0-9, a-f: aef, for example) as the encryption key for 64-bit WEP; input a 26-digit hexadecimal value (0-9, a-f: abcdef, for example) for 128-bit. Confirm Network Key: Enter the same network key to confirm. Key Index (advanced): Select one of the four keys to be the data encryption key. advanced This screen allows you to configure more advanced settings, such as Power Save and Wireless Mode. Power Save: Select one of three options. None This keeps the card in active mode. Min This places the card in a power saving mode when it s idle, though some components of the card are still alive, or active. When this option is selected, the power consumption is greater than Max. CONFIGURATION 15

16 Max This places the card in a power saving mode when it s idle. Wireless Mode: Select one of two options b This card is compatible with both g and b wireless stations, but if you prefer to limit network access to b wireless stations only, you can set the card to this mode g/b If you have a mix of b and g wireless stations in your network, this setting is recommended. RTS Threshold: Enter the minimum packet size required for an RTS (request to send). For packets smaller than this threshold, an RTS is not sent and the packet is transmitted directly to the wireless network. Select a setting within a range of 0 to 2432 bytes. Channel Plan: Select from the drop-down menu based on your locale. Set Defaults: Return any changed settings to default values. Apply: Click for any changes to take effect. status This screen displays details that include some current settings and information that may be needed for registration purposes and such. 16 CONFIGURATION

21 frequently asked questions What is the IEEE g standard? g is an IEEE standard for high-speed wireless LAN communications, providing a data rate of up to 54 Mbps in the 2.4 GHz band. It defines the use of the same OFDM modulation technique specified in IEEE a for the 5 GHz frequency band and applies it in the same 2.4 GHz frequency band as IEEE b. The g standard requires backward compatibility with b. The standard specifically calls for: A new physical layer for the 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 b, including CCK for 11 and 5.5 Mbps and Barker code modulation for 2 and 1 Mbps. A protection mechanism called RTS/CTS that governs how g devices and b devices interoperate. What is ad hoc? An ad hoc-integrated wireless LAN is a group of computers, each with 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. 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 a central database, or wireless application for mobile workers. 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. What is WEP? Wired Equivalent Privacy is a data-privacy mechanism based on a 40- bit shared-key algorithm as described in the IEEE standard. FAQ 21

22 What is WPA? WPA is a more powerful security technology for Wi-Fi networks than WEP. It provides strong data protection by using encryption as well as strong access controls and user authentication. WPA utilizes 128-bit encryption keys and dynamic session keys to ensure your wireless network s privacy and enterprise security. What is TKIP? TKIP is a quick-fix method to quickly overcome the inherent weaknesses in WEP security, especially the re-use of encryption keys. TKIP is involved in the IEEE i WLAN security standard. 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 i standard. What is DSSS? FHSS? What s the difference? 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 shortduration 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, 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 re-transmission. To an unintended receiver, DSSS appears as low-power wideband noise and is rejected (ignored) by most narrowband receivers. 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 bandwidth efficiency for reliability, integrity and security. In other words, more bandwidth is 22 faq

23 consumed than in the case of narrowband transmission, but the tradeoff produces a signal that is, in effect, louder and thus easier to detect, provided 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). specifications General Standards: - IEEE b (11 Mbps Wireless LAN) - IEEE g (54 Mbps Wireless LAN) - IEEE e (Wi-Fi Multimedia (WMM) - IEEE i (Wireless Encryption) - IEEE 802.1X (RADIUS Authentication) Bus type: 32-bit PCI card Chipset: Realtek 8185L Frequency band: GHz (Industrial Scientific Medical Band) Security: - 64/128-bit WEP data encryption - WPA and WPA2 - IEEE 802.1X RADIUS Authentication Detachable 2 dbi dipole antenna Maximum coverage distance: 100 m / 328 ft.
