SCALANCE network components
4.6 SCALANCE W components for the Industrial Wireless LAN
Industrial Ethernet
208 System Manual, 09/2019, C79000-G8976-C242-10
● Frame aggregation
● Channel bonding
Support of IEEE 802.11ac
The SCALANCE W1700 devices support the IEEE 802.11ac standard. The data throughput
for these devices is up to 1733 Mbps. Detailed information is available in the section "IEEE
802.11n/ac (Page 209)". These devices also support the following functions:
● Multi-User MIMO
● Spatial multiplexing
● Shortened guard interval
● Frame aggregation
● Channel bonding
● Channel width up to 160 MHz
SCALANCE W devices as bridges
A bridge is a network component that connects two networks. A bridge is not dependent on
the protocol; management of the data packages is based on the physical address of the
network nodes, the MAC address. The SCALANCE W provides bridge functionality for
handling data exchange between wired and wireless Ethernet.
● Learning Table
SCALANCE W devices log the information about which MAC address can be reached
over which port in a learning table.
● NAPT: Network Address Port Translation
With Network Address Port Translation (NAPT) or Port Address Translation (PAT),
several internal source IP addresses are translated into the same external source IP
address. This function is only available on clients in client mode.
Special functions for industrial applications
The following functions are used especially in an industrial environment and are available,
depending on the version, for the SCALANCE W devices via the KEY-PLUG or CLP.
● IPCF: Industrial Point Coordination Function
iPCF is the functional expansion of the IEEE 802.11 standard for applications requiring
real time and a deterministic response (predictable reply times). This allows Rapid
Roaming of mobile nodes from one RF field to the next. In addition, wireless and security-
related PROFINET IO communication via PROFISAFE is supported.
