[. . . ] Regulatory notes and statements Wireless LAN, Health and Authorization for use Radio frequency electromagnetic energy is emitted from Wireless LAN devices. The energy levels of these emissions however are far less than the electromagnetic energy emissions from wireless devices such as mobile phones. Wireless LAN devices are safe for use frequency safety standards and recommendations. The use of Wireless LAN devices may be restricted in some situations or environments for example: ·On board of airplanes, or ·In an explosive environment, or ·In case the interference risk to other devices or services is perceived or identified as harmful In case the policy regarding the use of Wireless LAN devices in specific organizations or environments (e. g. [. . . ] Data Rate: Shows the statistics of data transfer, and the calculation is based on the number of packets transmitted and received. Configuration This screen is where you set the basic wireless settings for the Wireless LAN USB 2. 0 Adapter 12 SSID: Service Set Identifier, which is a unique name shared among all clients in a wireless network. The SSID must be identical for each client in the wireless network. Wireless Mode: There are two modes available for selection Infrastructure ­ to establish wireless communication with the LAN and other wireless clients through the use of Access Points. Ad-Hoc ­ to establish point-to-point wireless communication directly with other wireless client devices. AdHoc Band: There are two bands available for selection- 11B and 11G Channel: The channel the AP operates on. Users can select the channel range of 1 to 11 for North America (FCC) domain and 1 to 13 for European (ETSI) and Japan (MKK) domains. Power Mode: There are 3 modes to choose from. Continuous Access Mode (default) ­ the Wireless LAN USB 2. 0 Adapter is constantly operating with full power. Maximum Power Save ­ the Wireless LAN USB 2. 0 Adapter consumes the least power. This mode only operates when there is wireless network activity. Power Save ­ the Wireless LAN USB 2. 0 Adapter consumes moderate level of power. Preamble: Select Long or Short & Long Preamble type. Preamble is a sequence of bits transmitted at 1Mbps that allows the PHY circuitry to reach steady-state demodulation and synchronization of bit clock and frame start. Two different preambles and headers are defined: the mandatory supported Long Preamble and header, which interoperates with the 1Mbps and 2Mbps DSSS specification (as 13 described in IEEE 802. 11), and an optional Short Preamble and header (as described in IEEE 802. 11b). At the receiver, the Preamble and header are processed to aid in demodulation and delivery of the PSDU. The Short Preamble and header may be used to minimize overhead and, thus, maximize the network data throughput. However, the Short Preamble is supported only for the IEEE 802. 11b (High- Rate) standard and not for the original IEEE 802. 11 standard. That means that stations using Short-Preamble cannot communicate with stations implementing the original version of the protocol. Click "Apply" to save the changes. Support Band: There are 2 modes the user can select; 11B and 11G. Advanced This screen is where you configure the Security settings for the Wireless LAN USB 2. 0 Adapter. Encryption: The following options are available: Open System, Shared Key, Auto, WPA/WPA2 and WPA-PSK/WPA2-PSK. [. . . ] Configure This screen shows the SSID, BSSID (MAC Address) and connected wireless client list information. The SSID of any wireless device must match the SSID typed here in order for the wireless device to access the LAN via the TEW-424UB in AP mode. 27 Channel: Select a transmission channel for wireless communications. The channel of any wireless device must match the channel selected here in order for the wireless device to access the LAN and WAN via the WLAN Router. (When in FCC domain, you could chose ch1~ch11; in ETSI domain, you could chose ch1~ch13) Network Authentication: The authentication type default is set to "OPEN_SYSTEM". There are four options: OPEN_SYSTEM, SHARED_KEY, WPA_PSK, WPA2_PSK. [. . . ]
