Figure 12: Roaming Between Access Points

Roamiing

RadioLAN networks provide an automatic ability in the client stations to select the Access Point with the best signal. This allows the client stations to move from one Access Point to another without user intervention.

For instance, a portable computer using the

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

RadioLAN Model 140 card may easily move

 

 

 

 

 

 

 

 

 

 

 

 

from one area of the building to another area

 

 

 

 

 

 

 

 

 

 

 

 

served by a separate Access Point, while

 

 

 

 

 

 

 

 

 

 

 

 

receiving 10Mb service. This allows the user

to take the computer from the office area, to a

 

 

 

 

 

 

 

 

 

 

 

 

conference room and continue to work on the

 

 

 

 

 

 

 

 

 

 

 

 

network.

The client stations software manages the relationship to the nearest access point, and

when conditions change, the client station will notify the new Access Point that it is selected

to provide service for that client, and the old Access Point to discontinue service. This is performed automatically and seamlessly.
