Properties of the SCALANCE W1700 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.
● IEEE 802.11ac
High Speed WLAN standard (wireless LAN) with a gross transmission speed of up to 1733
Mbps.
● IEEE 802.11r
Optimization of roaming (Fast BSS Transition)
● The WLAN interface is compatible with the standards IEEE 802.11n.
● 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 (RADIUS), WPA-PSK, WPA2 (RADIUS),
WPA2-PSK and IEEE 802.1x and the encryption methods WEP, AES and TKIP.
Note
With devices operated in WLAN mode IEEE 802.11n/ac, only WPA2 (WPA2-PSK and
WPA2 Radius) encryption is possible.
● 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.
