Redundant Wireless LAN (RWLAN)
RWLAN allows a redundant, wireless connection between two SCALANCE W78x devices
with at least two WLAN interfaces. This is used to set up a redundant wireless backbone that
cannot be implemented as a wired network due to its location but nevertheless has high
demands in terms of availability.
Two alternative configurations are possible. The RWLAN partner can be configured both
using its name and its MAC address.
