Encryption Default Key Key1 Key2 Key3 Key4 Authentication Operational Setting Fragmentation Setting RTS Threshold Preamble Type The ME102 Wireless access point supports 40-bit WEP data encryption. (40-bit WEP data encryption is also called 64-bit WEP data encryption by some vendors.) This parameter enables/disables encryption and select the 40-bit WEP data encryption key to use. Up to four keys can be defined in the access point. The possible values for this parameter are Disable, Key1, Key2, Key3, and Key4. . For more explanation on data encryption, please refer to the wireless network fundamental chapter at the beginning of this reference guide. The WEP data encryption method and the key used must be the same for all wireless nodes and access points in the same network. Note: the present version of the USB Configuration Utility software does not support WEP Passphrase. One of the four data encryption keys defined in the access point. Each data encryption key contains five hexadecimal numbers, making it 40 bits wide. Together with the twenty-four factory-set bits to make up a 64-bit encryption key. One of the four data encryption keys defined in the access point. One of the four data encryption keys defined in the access point. One of the four data encryption keys defined in the access point. Configurable between Open System (WEP disabled), Shared Key (40bit WEP data encryption), and Both. This is 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 2346. The packet size that 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, waits for the receiving station to send back a CTS packet before sending the actual packet data. The default value for RTS Threshold is 2346. A long transmit preamble allows the receiver to lock into the received bit patterns more easily. A short transmit preamble provides better performance. The default value is Long Preamble. 12
