ROAMING

WLAN-1

General info about roaming:

Roaming is always used in those cases where the client moves around in a large area,
covered by more than one Access Point. Compared with point-to-point radio links and

other PPP connections, which in most cases have a fixed channel selection, clients must be
able to find several access points on different channels in case of a roaming setup. Settings

on this page allow specifying the transition from one to another network for trouble-free
and optimised function.

SNR roaming threshold (dB):
This threshold specifies, starting from which dB value roaming is initiated. As soon as the

dB value falls short of the value specified, the roaming process will start.
Number of packets below threshold:
Specifies the quantity of packages for the underflow of the value.
SNR neighbour roaming trigger value:
The client is also processing packets from other Access Points on the same or on

neighbour channels. Roaming with such an Access Point will be initiated as soon as
packets are received, the SNR value of which is better.

Note:
A more detailed description for optimised roaming function configuration is shown in the

"Advanced roaming parameters" application example.
