under the control of the network's administrators, and can potentially open up
critical holes in a network's security policy.

2.2.3 Captive Portal

The NXC can be configured with a captive portal, which intercepts all network
traffic, regardless of address or port, until a connecting wireless user
authenticates his or her session, through a designated login Web page.
Figure 8 Applications: Captive Portal
The captive portal page only appears once per authentication session. Unless a
user idles out or closes the connection, he or she generally will not see it again
during the same session.

2.2.4 Load Balancing

With load balancing you can easily distribute wireless traffic across multiple APs to
relieve strain on your network. When a station becomes overloaded, it can
automatically delay a connection until the client associates with another network,
or it can alternatively disassociate idle clients or those clients with weak
connections from the network.

2.2.5 Dynamic Channel Selection

The NXC can automatically select the radio channel upon which its APs broadcast
by scanning the area around those APs and determining what channels are
currently being used by other devices not connected to the network.
