If there is a high demand for WLAN capacity in a certain coverage area, which of the following should be considered by the construction method?

Question

Options

• AIndoor distribution system combination
• BCombined circuit of outdoor distribution system
• CIndoor installation
• DOutdoor AP+directional antenna

• A
  7% (3)
• B
  4% (2)
• C
  76% (35)
• D
  13% (6)

Explanation

Indoor installation (C) is correct because placing APs directly inside a high-demand coverage area positions them close to users, yielding better signal quality, higher data rates, and efficient spatial frequency reuse - all of which directly increase capacity rather than just extending coverage.

Why the distractors are wrong:

• A (Indoor distribution system combination): An indoor DAS splits transmit power across many passive antennas - it is optimized for coverage uniformity, not capacity density, so it underperforms when throughput demand is high.
• B (Combined circuit of outdoor distribution system): Outdoor distribution systems target wide-area coverage scenarios; they are not designed to serve concentrated indoor demand and introduce unnecessary path loss through building walls.
• D (Outdoor AP + directional antenna): Directional antennas boost range but cannot match the per-user capacity achieved by APs physically co-located with users inside the target space; this method suits difficult-to-access areas, not high-demand zones.

Memory tip: Capacity = Closeness. High demand means you need APs inside and near users - "indoor installation" puts the radio where the traffic is.
