7.5 Wireless Roaming
In order to maintain the data connection in a mobile application or in an environment
with changing reception conditions, the quality of the WLAN connection is continu
-
ally checked and, if required, a connection to other, better-positioned access points
(AP) is established.
For this the HG G
76343/4/5 must also scan for alternative APs on other channels in
the specified frequency range. This short-term change of the channel impedes the
ongoing data transmission. Therefore parameters are provided which make this scan
procedure and the criteria for the change to another AP adjustable so that the data
connection can be kept as stable as possible in accordance with the conditions of
use.
7.5.1 Roaming Parameter
The roaming behavior of the radio modem is determined by the following parame
-
ters:
The chosen frequency band (2.4 and/or 5 GHz)
An SNR threshold that determines whether the HG G
76343/4/5 is looking for
other APs in short or long time intervals.
Specifies a (long) interval with which the radio modem scans the specified
channels when the SNR value is
higher
than the specified threshold.
Specify a (short) interval with which the radio modem scans the specified chan
-
nels when the SNR value is
lower
than the specified threshold.
Configure specific channels that the HG G
76343/4/5 is to scan.
