Possible applications of the SCALANCE W786
The SCALANCE W786 is equipped with an Ethernet port and up to three wireless LAN ports.
This makes the device suitable for the following applications:
●
The SCALANCE W786 forwards data within its transmission range from one node to
another without a connection to wired Ethernet being necessary.
●
The SCALANCE W786 can be used as a gateway from a wired to a wireless network.
●
The SCALANCE W786 can be used as a wireless bridge between two networks.
●
The SCALANCE W786 can be used as a bridge between two cells operating at different
frequencies.
With a SCALANCE W786 with more than one WLAN port, you can also implement a
redundant wireless connection to a SCALANCE W78x with at least two WLAN ports.
Properties of the SCALANCE W786
●
The Ethernet interface supports 10 Mbps and 100 Mbps, both in full and half duplex as
well as autocrossing and autopolarity.
●
Operating the wireless interface in the frequency bands 2.4 GHz and 5 GHz.
●
The wireless interface is compatible with the standards IEEE 802.11a, IEEE 802.11h,
IEEE 802.11b and IEEE 802.11g. In the 802.11a, 802.11h 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).
●
As an expansion of the 802.11a mode, it is also possible to operated according to the
IEEE 802.11h standard. In 802.11h mode, the procedures Transmit Power Control (TPC)
and Dynamic Frequency Selection (DFS) are used in the range 5.25 - 5.35 and 5.47 -
5.75 GHz. In some countries, this allows the frequency subband of 5.47 - 5.725 GHz to
be used outdoors even with a higher transmit power.
TPC is a technique of controlling the transmit power by reducing it to the strength actually
required. With dynamic frequency selection (DFS), the access point searches for primary
users (for example radar) on a randomly selected channel before starting communication.
If signals are found on the channel, this channel is disabled for 30 minutes and the
availability check is repeated on another channel.
●
Support of the authentication standards WPA, WPA-PSK, WPA2, WPA2-PSK and
IEEE 802.1x and the encryption methods WEP, AES and TKIP.
●
Suitable for inclusion of a RADIUS server for authentication.
●
Device-related and application-related monitoring of the wireless connection.
●
The interoperability of the devices with Wi-Fi devices of other vendors was tested
thoroughly.
Note
In client mode, you can use a SCALANCE W786-xPRO with the functionality of a
SCALANCE W746-1PRO.
