The primary use case for this feature is if an AP has some remotes that are close to the AP and could
support a higher data rate and some farther away that can only support a lower data rate. This mode
allows the close remotes to take advantage of the higher data rate for the uplink, when otherwise the
whole network would have had to be run at the lower data rate. This feature will not give the optimal data
rates if all remotes can support the higher data rate, because all downlink traffic will be sent at a lower
data rate.
Security
Setting the security mode to EAP or PSK will enable device authentication. When enabled, the remotes
will authenticate with the AP (PSK) or a backend RADIUS server (EAP) before they are allowed to pass
data on the network. The authentication protocol is compliant with IEEE 802.1X. If device
authentication is enabled, over the air data encryption can also be enabled. This ensures all over the air
traffic is protected. When encryption is enabled, the device must occasionally rotate the encryption keys.
This rotation is logged in the event log with event type nx_auth. These events can be suppressed in the
event log configuration to prevent them from filling the event log. See section 3.6.2 for instruction on
controlling the event log.
