Chapter 6 Wireless LAN
Figure 15   Roaming Example
The steps below describe the roaming process.
As wireless station Y moves from the coverage area of access point AP 1 to that of access 
point 
2 AP 2, it scans and uses the signal of access point AP 2
Access point AP 2 acknowledges the presence of wireless station Y and relays this 
information to access point AP 1 through the wired LAN. 
Access point AP 1 updates the new position of wireless station.
Wireless station Y sends a request to access point AP 2 for reauthentication.
6.4.1  Requirements for Roaming
The following requirements must be met in order for wireless stations to roam between the 
coverage areas. 
All the access points must be on the same subnet and configured with the same ESSID. 
If IEEE 802.1x user authentication is enabled and to be done locally on the access point, 
the new access point must have the user profile for the wireless station.
The adjacent access points should use different radio channels when their coverage areas 
overlap. 
All access points must use the same port number to relay roaming information. 
The access points must be connected to the Ethernet and be able to get IP addresses from 
a DHCP server if using dynamic IP address assignment.
