2.6.3 Roaming
This feature automatically switches one Access-Point to another in where two or more
Access-Points with the identical SSID code exist are installed.
1. Searches for Access-Points that can communicate with the terminal, and lists up radio wave
status of each Access-Point.
2. Compares radio wave status of the currently connected Access-Point with those for the listed
Access-Points.
3. If the comparison proves that one of the listed Access-Points has a better radio wave status than
the one currently being connected with the terminal, the terminal will make a request of
roaming to that Access-Point.
4. If roaming permission comes from the Access-Point to the terminal, the roaming will complete.
Note that if the roaming fails, the connection establishment will be disconnected and then
connected again.
Notes:
• In some cases, the Access-Point may request the terminal for forcible roaming or
reconnection with another Access-Point.
• If connection establishment of the Access-Point being connected with the terminal is
terminated due to some reasons such as turning off the power on it, the terminal may be
forced to make a connection with another Access-Point.
• If it takes time for Access-Point to correspond for roaming request made by the terminal, the
reconnection process may be initiated.
• If DeAuthentication or DisAssociation message issued by the Access-Point that is
being connected with the terminal is received by the terminal after roaming completed, the
connection establishment between the Access-Point and the terminal may be interrupted
temporarily and then connected again.
