Routing Mode
If the device is configured in Routing mode, both Ethernet and Wireless interfaces require an IP address. The following
screen is displayed:

Roaming
Roaming Overview
Roaming is a feature by which an SU terminates the session with the current BSU and starts the registration procedure
with another BSU when it finds the quality of the other BSU to be better. Roaming provides MAC level connectivity to the
SU that roams from one BSU to another. Roaming takes place across the range of frequencies and channel bandwidths
(5, 10, or 20 MHz, as available) that are available per configuration. The current release offers handoff times of up to a
maximum of 80 ms. This is fast enough to allow the SU to seamlessly roam from one BSU to the other therefore
supporting session persistence for delay-sensitive applications. The feature also functions as BSU backup in case the
current BSU fails or becomes unavailable.
The Roaming feature lets the SU monitor local SNR and data rate for all frames received from the current BSU. As long
as the average local SNR for the current BSU is greater than the slow scanning threshold, and the number of
retransmitted frames is greater than the slow scanning threshold given in percentage, the SU does not scan other
channels for a better BSU.
