Which of the following is controlled by the coverage area size of AP? (Multiple choice)

Question

Options

• AAdjust the angle of the AP antenna
• BAdjust the transmit power of the AP
• CAdjust the power supply of AP
• DAdjust the access bandwidth of the AP

• A
  79% (55)
• C
  9% (6)
• D
  13% (9)

Explanation

Adjusting the antenna angle (A) directly shapes the radiation pattern of the AP - tilting or rotating the antenna physically changes the direction and coverage footprint. Adjusting the transmit power (B) controls how far the radio signal travels, so higher power expands the cell size and lower power shrinks it; this is the most common method for controlling cell size in enterprise WLAN design.

C is wrong because the power supply (AC/PoE voltage) keeps the AP running but has no direct relationship to RF coverage area - it's an electrical concern, not a radio one.

D is wrong because access bandwidth (throughput/data rate settings) affects how much data can flow through the AP, not how large or small the radio coverage zone is.

Memory tip: Think of AP coverage like a flashlight - the angle of the beam (antenna) and brightness (transmit power) determine how far and wide the light reaches. Changing the battery type (power supply) or the bulb's wattage rating (bandwidth) doesn't reshape the beam.
