Describes dual roaming and the block time
A device with just 1 WLAN module will lose its connection to the infrastructure in a handover scenario.
However, a device with 2 WLAN modules can use PRP to reduce interruptions if the corresponding LANconfig setting prevents both WLAN modules from roaming at the same time. This mode is called dual roaming.
A practical example is a client moving past an access point. Due to the design of the network, one WLAN module stays connected and receives PRP packets, while the other WLAN module can already associate with the next AP.
A concrete example would be for materials management, and for the real-time monitoring of inventory flow in particular.
Another example is the railway. An AP in a train connects to the trackside APs throughout the journey.
In addition, you can specify the block time in LANconfig. The block time specifies the minimum time that passes before the different WLAN modules of the same device can perform roaming operations.
