Usage Guidelines

The decision period for agile distributed SFN roaming helps you adjust the roaming sensitivity. A shorter period indicates a higher sensitivity. A large value causes the slow roaming switchover, affecting user experience. A small value causes frequent roaming switchovers, affecting system performance. The default value is recommended. Ensure that the interval at which RUs report STA RSSIs is smaller than the decision period for agile distributed SFN roaming.

Example

# Set the default decision period for agile distributed SFN roaming to 800 milliseconds.
