Redundant Wireless LAN (RWLAN)
RWLAN allows a redundant, wireless connection between two SCALANCE W access points
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.
Roaming
Clients moving between wireless cells: "Roaming"
To allow mobile nodes to be able to roam seamlessly from one access point to the next, the
individual wireless cells must overlap. This is transparent for the application. The access
points need to be interconnected via Industrial Ethernet or a wireless distribution system
(WDS).
