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). 
The following graphic shows the wireless connection of a mobile station over two wireless 
cells (roaming).
