Figure 80 Roaming Example
The steps below describe the roaming process.
Wireless station Y moves from the coverage area of access point AP 1 to that of
1
access point AP 2.
Wireless station Y scans and detects the signal of access point AP 2.
2
Wireless station Y sends an association request to access point AP 2.
3
Access point AP 2 acknowledges the presence of wireless station Y and relays this
4
information to access point AP 1 through the wired LAN.
Access point AP 1 updates the new position of wireless station Y.
