Post-validation at a city warehouse shows a coverage null behind dense racking where AP density is already moderate and channels are clean. Power is near design maximum on the nearest AP, and the antenna is an integrated omni. What remediation is most appropriate?
Select an answer to reveal the explanation.
Short Explanation
If power is already high and the omni still cannot see behind racks, more watts will not invent geometry. Add or aim coverage where the null lives—do not rename the SSID and hope.
Full Explanation
Coverage nulls behind dense warehouse racking with clean channels and near-max power on an integrated omni are geometry problems, not naming or channel-width tricks. The appropriate remediation is to add an AP or relocate coverage with an appropriate antenna pattern rather than only raising power further on an already hot omni cell. More power on the same omni rarely fills racking shadows and increases interference to neighboring aisles that already meet design.
Renaming the SSID so clients somehow fill the null fails by concept: SSID names do not change RF propagation through racking. Disabling validation metrics to accept the predictive map fails by concept: rejecting measured reality does not cover the null. Widening every channel to 160 MHz to compensate for missing coverage fails by concept: wider channels do not create energy in a geometric shadow and worsen reuse.
Exam caveat: CWNE remediation prefers AP and antenna geometry fixes over max-power or channel-width myths when validation shows a physical null.
Operational check: Map the warehouse null relative to racking, evaluate an added AP or a directional or downtilted antenna aiming into the aisle, implement the geometry change, and re-survey before raising power again.
