Product characteristics

Properties of the SCALANCE W700 devices
● The Ethernet interface supports the following:
– 10 Mbps and 100 Mbps both in full and half duplex
– 1000 Mbps full duplex
– Autocrossing
– Autopolarity
● Operating the WLAN interface in the frequency bands 2.4 GHz and 5 GHz.
● The WLAN 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.
● IEEE 802.11n
High-speed WLAN standard (wireless LAN) up to 450 Mbps and can operate in the 2.4
GHz and in the 5 GHz range.
● IEEE 802.11h - Supplement to IEEE 802.11a
In the 802.11h mode, the methods "Transmit Power Control (TPC)" as well as "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 in the
outdoor area even with higher transmit powers.
TPC is a method of adapting the transmit power.
With DFS, the access point searches for primary users for 60 seconds before starting
communication on the selected channel. During this time the access point does not send
beacons. If signals are found on the channel, the channel is blocked for 30 minutes, the
access point changes channel and repeats the check. Primary users are also searched
for during operation.
● Support of the authentication standards WPA, WPA-PSK, WPA2, WPA2-PSK and
IEEE 802.1x and the encryption methods WEP, AES and TKIP.
Note
The transmission standard IEEE 802.11 n with the setting "802.11n" or "802.11 n only"
only supports WPA2/ WPA2-PSK with AES in the security settings.
● For better transmission via WLAN, the function WMM (wireless multimedia) is enabled.
The frames are evaluated according to their priority and sent prioritized via the WLAN
interface.
● 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.
