Fragment Threshold Network Type Power Save Mode Preamble Type Transmit Rate RTS Threshold When in Infrastructure mode, this field defines the Extended Service Set ID (ESSID). The ESSID assigned to the wireless node is required to match the access point ESSID in order for the wireless node to communicate with the access point. The default SSID is "Wireless". Indicates the packet length used for fragmentation. Packets larger than the size programmed in this field will be fragmented. The Fragment Threshold value must be larger than RTS Threshold value. The default value for Fragment Threshold is 2432. Configurable between 802.11 Ad-hoc and Infrastructure modes. In 802.11 Ad-hoc mode, the wireless nodes form their own local network where the end nodes communicate peer-to-peer without an access point. In Infrastructure mode, the wireless searches all available wireless channels to associate with an access point. The default value for Operating Mode is Infrastructure. The Power Save option is designed to conserve the battery life of your computer. When Power Save is enabled, your MA311 PCI Adapter will go into sleep mode to minimize power consumption. A long transmit preamble allows the receiver to lock into the received bit patterns more easily. A short transmit preamble provides better performance. An auto transmit preamble is either short or long, negotiated between the wireless node and the device it is communicating with. The default value is Long Tx Preamble. Allows you to define the data transfer rate. The default value is Auto. In this case, the best transfer rate is negotiated between the wireless node and the device it is communicating with. This could be another wireless node or an access point. Other possible values for this field are 1 Mbps, 2 Mbps, 5.5 Mbps, and 11 Mbps. The packet size the wireless node uses to determine if it should use the CSMA/CD mechanism or the CSMA/CA mechanism for packet transmission. With the CSMA/CD transmission mechanism, the transmitting station sends out the actual packet as soon as it has waited for the silence period. With the CSMA/CA transmission mechanism, the transmitting station sends out a RTS packet to the receiving station, and waits for the receiving station to send back a CTS packet before sending the actual packet data. 26
