Description
2.1 Network structures
Wireless access to a wired Ethernet network
If one (or more) access points have access to wired Ethernet, the following applications are
possible:
● A single device as gateway:
A wireless network can be connected to a wired network via an access point.
● Span of wireless coverage for the wireless network with several access points:
The 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 area covered by one access point to the area covered
by another access point, the wireless link is maintained (roaming).
