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.
