Which of the following statements about the on-site survey of the coverage area of indoor coverage scenarios is correct? (Multiple choice)

Question

Options

• AClearly define the bandwidth requirements for each area. Bandwidth requirements = total number
• BClarify the coverage strength and edge strength requirements for each area
• CIdentify the types of access terminals and frequency bands used in the area
• DWhen surveying, focus on collecting information about the areas that need to be covered, and

• A
  7% (3)
• B
  79% (33)
• D
  14% (6)

Explanation

When planning an indoor wireless coverage system, an on-site survey must capture the signal performance requirements and the device ecosystem - both of which directly shape the system design. Option B is correct because defining coverage strength (minimum signal level throughout the area) and edge strength (signal at coverage boundaries) sets the performance benchmarks the system must meet. Option C is correct because identifying terminal types and frequency bands determines which radio technologies and antennas must be supported, since different devices operate on different bands with different sensitivity levels.

Option A is wrong because while bandwidth requirements are relevant, the statement presents an oversimplified or incorrect formula ("bandwidth = total number") - proper bandwidth planning involves traffic models, concurrent users, and service types, not a single total-number figure. Option D is wrong because a proper survey cannot be limited only to "areas that need to be covered"; engineers must also assess the physical environment, building materials, interference sources, and signal propagation paths to design an effective system.

Memory tip: Think of the survey as answering two questions - "How strong?" (Option B: coverage and edge strength) and "What devices?" (Option C: terminals and frequency bands). These are the two non-negotiable inputs before any indoor DAS or small-cell design can begin.
