[. . . ] These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with this user's guide, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at his/her own expense. The equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment, under 47 CFR 2. 1093 paragraph (d)(2). [. . . ] Power Saving Mode ­ Place the adapter into power saving mode when it is idle. SSID Parameter Network Type Description Infrastructure ­ This operation mode requires the presence of an 802. 11 Access Point. All communication is done via the Access Point or Router. - 17 - Ad-Hoc ­ Select this mode if you want to connect to another wireless station in the Wireless LAN network without going through an Access Point or Router. Transmit Power If you wish to lower the transmit power of the card to save the power of your system, you can select the lower percentages from the list. The preamble defines the length of the CRC block for communication among wireless stations. If "Auto" mode is selected, the card will auto switch the preamble mode depending on the wireless stations which the card is connecting to. RTS Threshold 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. The value defines the maximum size of packets; any packet size larger than the value will be fragmented. If you have decreased this value and experience high packet error rates, you can increase it again, but it will likely decrease overall network performance. The channel setting should be the same with the network you are connecting to. 11B Preamble Type Fragment Threshold Channel - 18 - 4. 3. 2 Authentication vs. Security Under the profiles tab, you are able to specify the type of security/authentication mode used to connect with a wireless network. WPA requires a Radius Server to complete authentication among wireless stations and Access Points. 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. - 21 - To enable the WPA function in Windows XP, the following software systems are required: 1. Right-click the Windows wireless networks icon located on your taskbar as shown below. Select "View Available Wireless Networks" to open up the Wireless Networks window. Right-click the Hawking Wireless Configuration Utility icon on the taskbar. To turn on ZCU, make sure "Use Zero Configuration as Configuration Utility" is selected on the menu. Choose "Change Advanced Settings" from the left menu pane. - 22 - 4. In the Wireless Networks tab, select your preferred wireless network you are connected to and click on "Properties". - 23 - 5. Under the Association tab, select the type of Network Authentication your wireless network uses and determine the type of data encryption, if available. A list of network authentication terms is described on the next page. 6. If you need to configure network authentication, go to the Authentication tab. [. . . ] 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. 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. 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.
