link is dropped. Whenever a Client is not connected to an AP, it will cyclically scan all available
channels for a suitable AP.
Roaming
Clients may also roam between Access Points. If a Client receives a beacon from an AP with a
stronger signal than the current AP (providing SSID is the same and capability information are
compatible), it may disconnect from the first AP and establish a link with the second AP. This
functionality permits a client to have mobility whilst maintaining a link with the most suitable AP.
