Description of the SCALANCE W 700
Possible Applications of the SCALANCE W 788
The SCALANCE W 788 is equipped with an Ethernet interface and a wireless LAN
interface (SCALANCE W 788-2pro: two WLAN interfaces). This makes the device
suitable for the following applications:
● The SCALANCE W 788 forwards data within its transmission range from one
node to another without a connection to wired Ethernet.
● The SCALANCE W 788 is used as a gateway from a wired to a wireless net-
work.
● The SCALANCE W 788 can be used as a bridge between two networks.
Due to its second WLAN interface, the SCALANCE W 788-2pro can also be used
to implement a redundant wireless connection between two SCALANCE W 788-
2pro devices.
Properties of the SCALANCE W 788
● The Internet interface supports 10 Mbps and 100 Mbps, full duplex and half du-
plex in both cases.
● The wireless interface is compatible with the standards IEEE 802.11a,
IEEE 802.11b and IEEE 802.11g. In the 802.1a- and 802.1g modes, the trans-
mission rate is up to 54 Mbps.
● Operation in the 2.4 GHz and 5 GHz frequency bands.
● Support of the authentication standards WPA, WPA-PSK and
IEEE 802.1x and WEP, AES and TKIP encryption schemes.
● Suitable for inclusion of a RADIUS server for authentication.
● Device-related and application-related monitoring of the wireless connection.
Ports
The SCALANCE W 788 has the following ports:
● A Harting RJ-45 hybrid socket on the front panel of the housing for connection
of an Ethernet cable and for the power supply (hybrid connector for power over
Ethernet).
● An M12 socket for the power supply.
● Two R-SMA sockets (four R-SMA sockets on the SCALANCE W 788-2pro) for
the attachment of antennas on the sides of the device.
Note
In the version for USA/Canada, two fixed antennas are fitted. On the
SCALANCE W 788-2pro, the antennas of the second wireless card can be
detached. The second wireless card can only be operated at 2.4 GHz
