Usage Guidelines

The RSSI gap for agile distributed SFN roaming RUs helps you adjust the roaming sensitivity. A roaming switchover occurs when the RSSI gap between the local RU and a surrounding RU reaches the specified value. A large value causes the slow roaming switchover, affecting user experience. A small value causes frequent roaming switchovers, affecting system performance.

Example

# Set the RSSI gap for agile distributed SFN roaming RUs to 10 dB.
