Properties of the 802.11g Standard
The IEEE 802.11g is upwards compatible with IEEE 802.11b, both use the 2.4
GHz band. In contrast to 802.11b that specifies data rates up to 11 Mbps, 802.11g
provides for data rates up to 54 Mbps. The 802.11g standard also uses the OFDM
modulation scheme.
Special Options for 802.11g Settings
The options you can set in the Advanced G submenu relate to the way in which
management and control data (RTS/CTS frames, beacons) are sent in the 802.11g
mode. You can also specify that the SCALANCE W 788 only supports 802.11g-
compatible devices.
