P roperties of the SCALANCE W78x
● The Ethernet interface supports 10 Mbps and 100 Mbps, both in full and half
duplex as well as autocrossing and autonegotiation.
● Operating the wireless interface in the frequency bands 2.4 GHz and 5 GHz.
● Th e wireless interface is compatible with the standards IEEE 802.11a ,
IEEE 802.11b and IEEE 802.11g. In the 802.11a- and 802.11g mode, the
gross transmission rate is up to 54 Mbps. In turbo mode, the Transmission rate
is up to 108 Mbps (not permitted in all countries and modes).
