ADIO HARACTERISTICS
The IEEE 802.11a and 802.11g standards use a radio modulation technique
known as Orthogonal Frequency Division Multiplexing (OFDM), and a shared
collision domain (CSMA/CA). The 802.11a standard operates in the 5 GHz
Unlicensed National Information Infrastructure (UNII) band, and the 802.11g
standard in the 2.4 GHz band.
IEEE 802.11g includes backward compatibility with the IEEE 802.11b standard.
IEEE 802.11b also operates at 2.4 GHz, but uses Direct Sequence Spread
Spectrum (DSSS) and Complementary Code Keying (CCK) modulation technology
to achieve a communication rate of up to 11 Mbps.
The wireless bridge provides a 54 Mbps half-duplex connection for each active
channel (up to 108 Mbps in turbo mode on the 802.11a interface).
