Wireless Distribution System (WDS)
WDS allows direct connections between SCALANCE W access points and or between
SCALANCE W and other WDS-compliant devices. These are used to create a wireless
backbone or to connect an individual SCALANCE W to a network that cannot be connected
directly to the cable infrastructure due to its location.
