Characteristics of the WLAN Device
■The WLAN device is a
■The WLAN device operates in
■The Intel PRO/Wireless 3945ABG WLAN device is capable of three operating modes, IEEE802.11a, IEEE802.11b and IEEE802.11g.
■Encoding of data is modulated using Direct Sequence Spread Spectrum (DSSS) and Complementary Code Keying (CCK) when the WLAN device is operating in IEEE 802.11b mode and Orthogonal Frequency Divi- sion Multiplexing (OFDM) when operating in IEEE802.11a or IEEE802.11g mode.
■The WLAN device is
■The WLAN device supports the following encryption methods - WEP, TKIP, CKIP, and AES encryption.
