When deploying APs on multiple floors of a building, the factors that need to be paid attention to are (). (Multiple choice)

Question

Options

• AThe material of the wall
• BOther Interfering Signals
• CIn order not to affect the appearance, the AP should be hidden in the ceiling
• DUnified channel planning

• A
  75% (47)
• C
  25% (16)

Explanation

When deploying APs across multiple floors, wall material (A) directly determines signal attenuation - concrete, metal, and reinforced structures can significantly block or weaken RF signals between floors, making material awareness critical for coverage planning. Interfering signals (B) from neighboring networks, Bluetooth devices, or other APs operating on the same frequency bands degrade throughput and reliability, so a site survey is essential. Unified channel planning (D) prevents co-channel and adjacent-channel interference between APs on different floors that may overlap in coverage, which is especially important in multi-story deployments where vertical signal bleed is common.

Option C is wrong because AP placement must prioritize signal coverage and network performance - hiding an AP purely for aesthetic reasons can create dead zones, cause multipath issues, or weaken signal unnecessarily; aesthetics are a secondary concern to RF engineering.

Memory tip: Think "WAC without C" - Wall material, Adjacent interference, Channel planning are the three engineering fundamentals. The "hide it for looks" option is a trap because wireless deployment is always function over form.
