The power of AP installed indoors is generally () mW.

Question

Options

• A100
• B500
• C800
• D50

• A
  79% (19)
• B
  13% (3)
• C
  4% (1)
• D
  4% (1)

Explanation

Indoor APs are typically rated at 100 mW (20 dBm) because this power level is sufficient to cover standard indoor spaces while complying with regulatory limits set by bodies like the FCC and similar agencies worldwide - higher power indoors causes unnecessary interference and doesn't meaningfully improve coverage due to walls and obstructions absorbing signal.

Why the distractors are wrong:

• B (500 mW) and C (800 mW) are far too high for indoor use; power levels in that range are associated with outdoor or long-distance point-to-point wireless links, not indoor APs.
• D (50 mW) is too low and typically associated with low-power or personal devices (like some IoT sensors), not standard enterprise or consumer indoor APs.

Memory tip: Think "1-0-0 indoors" - 100 mW is the sweet spot that balances regulatory compliance, adequate coverage, and minimal co-channel interference in enclosed environments. If you see a value in the hundreds above 100 or below 100, those are either outdoor-grade power or underpowered devices.
