Two civic-center APs are planned on overlapping adjacent 40 MHz channels and clients show degraded throughput. What interference mechanism should the expert diagnose?
Select an answer to reveal the explanation.
Short Explanation
Overlapping 40 MHz neighbors are like two bands playing in half-shared rooms — the leftover splash is ACI, not the same song as classic CCI. Fix the channel plan and widths. More SSIDs or DHCP hunts won't clean the spectrum skirts.
Full Explanation
Adjacent-channel interference occurs when partially overlapping channel masks inject energy into neighboring channels, degrading SNR and efficiency. It differs from co-channel contention where devices share the same channel and defer via CSMA/CA. Remediation centers on non-overlapping channel width and reuse plans, not SSID or DHCP changes.
