Wireless access to a wired Ethernet network
If one (or more) SCALANCE W78x access points have access to wired Ethernet, the
following applications are possible:
●
A single SCALANCE W78x as gateway:
A wireless network can be connected with a wired network over a SCALANCE W78x.
●
Span of wireless coverage for the wireless network with several SCALANCE W78x
access points:
The SCALANCE W78x access points are all configured with the same unique SSID
(network name). All nodes that want to communicate over this network must also be
configured with this SSID.
If a mobile station moves from the coverage range (cell) of one SCALANCE W78x to the
coverage range (cell) of another SCALANCE W78x, the wireless connection is
maintained (this is called roaming).
