3.2.2 Infrastructure mode using WLAN controller
In an industrial environment, the infrastructure mode is usually created in two different ways:
• Several access points are connected to a network. All are operated with the same SSID. Each ac-
cess point operates independently and has to be configured independently.
• Several access points are connected to a WLAN controller. The WLAN controller controls all access
points in the same way. A central computer administrates the network and sets its parameters. This
structure is most frequently used in an industrial environment.
3.2.3 Diagnosis
Various simple diagnostic tools are available that can be used to capture basic information on the WLAN
network.
There are Android apps (usually free of charge) for simple analyses. There is also software for Windows
computers that offer these functions.
InSSIDer: With this app, a smartphone can be used as a simple WLAN measurement device. It provides
graphical representations of the available networks using the SSID in the range of 2.4 and 5 Ghz (if the
smartphone supports this). This offers a clear overview of available stable networks and also indicates the
reception quality. The network conditions or if a hotspot with netsh is active can be easily determined.
WiFi Analyzer: Provides similar functions as InSSIDer.
