Usage Guidelines

The cumulative RSSI change threshold of agile distributed SFN roaming STAs helps you adjust the roaming sensitivity. A roaming switchover occurs when the cumulative RSSI change value reaches the specified threshold. A large value causes the slow roaming switchover, affecting user experience. A small value causes frequent roaming switchovers, affecting system performance.

Example

# Set the cumulative RSSI change threshold for agile distributed SFN roaming STAs to 10 dB.
