When designing a multi-floor deployment in RUCKUS Wi-Fi Planner, which adjustment best prevents co-channel interference...

To minimize co-channel interference (CCI) in multi-floor Wi-Fi environments, planners should assign different non-overlapping 2.4 GHz channels per floor —typically channels 1, 6, and 11.

According to RUCKUS One Online Help – RF Planning Best Practices , overlapping floors can cause vertical signal leakage, leading to channel contention and performance degradation. The RUCKUS Wi-Fi Planner allows layer-based channel mapping to simulate floor separation and interference.

While reducing transmit power can complement this strategy, channel segregation remains the primary CCI mitigation method. Increasing AP density or enabling SmartMesh does not resolve channel reuse conflicts in vertical topologies.
