This high-speed Card provides you with an innovative wireless networking solution that is easy to set up and use. The Card transmits at a rate of 11, 5. 5, 2 or 1Mbps to let you share files and printers on the network--without the hassle and inconvenience of connecting wires!Operating in the ISM band using Direct Sequence Spread Spectrum (DSSS) transmission, the Card implements the IEEE 802. 11b standard and supports many devices running the Windows CE operating system. [. . . ] First, each device must be set to the same SSID. Secondly, each device must be set to the same Ad-Hoc Channel. For instance, if there are two devices on the same wireless network, and the SSID is "WLAN" and the channel is "11", then each device must be set for SSID = "WLAN" and Ad-Hoc Channel = "11". The encryption rate (64- or 128-bit) must be identical for each device's encryption key. Next to "Ad-Hoc Channel", press the up or down arrow until the desired channel appears in the box. Click "Apply" to save the changes. 20 wireless networking Encryption For security, the 802. 11b standard incorporates a method of "scrambling" the data being sent over the air. This is called WEP (Wired Equivalent Privacy). There are two different levels of WEP: 64-bit encryption and 128-bit encryption. 64-bit encryption is powerful and secure. 128-bit encryption is very powerful and very secure. The reason that two levels, or rates, of encryption exist, is that the encryption process slows down the data speed. The higher the rate of encryption, the slower the data will be transmitted. 64-bit encryption will reduce data rates nearly 30-40 percent where 128-bit encryption will reduce data rates around 50-60 percent. The trade-off is slower performance for higher security. Keep in mind, however, only large file transfers or continuous streaming data are most affected by this. Normal browsing of the Internet, downloading files, and sending and retrieving e-mails are not affected. How to Use Encryption Encryption is fairly easy to understand. Encryption uses what are called "keys" to decode or "unscramble" data. Keys can be made by entering a passphrase (password) or can be entered manually into the system using a series of two-digit numbers (called hexadecimal). In Infrastructure mode, where an access point or wireless router is being used, the access point or wireless router is programmed with an encryption key. For a wireless device to connect to the wireless network, the same encryption key must be programmed into the device. Your Card can be programmed with a key in either the passphrase manner or with the series of two-digit numbers called hexadecimal (or hex). 21 wireless networking To create an encryption key using a passphrase: 1.

[. . . ] These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy. If not installed and used in accordance with the instructions, it may cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try and correct the interference by one or more of the following measures: · Reorient or relocate the receiving antenna. · Increase the distance between the equipment and the receiver.
