    Access Point (AP) products available on the market Architecture today. There is, however, one critical difference that sets it apart: the AirFlow dis- tributed architecture. Whereas ordinary APs integrate radio and security protocols in a single unit, the AirFlow AP distributes this intelligence across a central Air- Switch connected by Ethernet cables to multiple packet antennas called AirHubs.

Autostart and AutoRestart Starting up individual AirHubs requires no action from the system administrator. As soon as the switch is booted up, it detects all connected packet antennas, sends them all required configuration parameters, and places them in Active mode.

    System Manual • I. Product Features For a more reliable security solution, AirFlow currently recommends using the Air- Switch in combination with a layered security regimen incorporating technologies such as 802.1x and IPSec. Individual entries to the ACL can be added one at a time through the CLI. Existing lists can be imported from an Excel spreadsheet, for convenience and accuracy.
