Under normal circumstances the WLAN client would only log onto another
access point if the connection to the access point used up to that point was
lost completely (hard roaming). Soft roaming on the other hand enables the
client to use scan information to roam to the strongest access point. With the
background scanning function, the BAT device in client mode can gather in-
formation on other available access points prior to the connection being lost.
In this case the client is not switched to another access point once the exist-
ing connection has been lost completely, but rather when another access
point within its range has a stronger signal.
V To enable soft roaming, change to Setup > Interfaces > WLAN > Roaming
in WEBconfig or Telnet and select the physical WLAN interface.
V Enable soft roaming and, if required, set the other parameters (such as
threshold levels and signal level). Please refer to the reference handbook
for further information on these parameters.
V To configure background scanning in LANconfig, go to the 'Radio' tab un-
der the physical WLAN settings for the desired WLAN interface.
V Enter the background scan interval as the time in which the BAT device
cyclically searches the currently unused frequencies of the active band for
available access points. To achieve fast roaming, the scan time is restrict-
ed to e.g. a minimum of 260 seconds (2.4 GHz) or 720 seconds (5 GHz).
