Which of the following statements about WLAN indoor channel planning is wrong?

Question

Options

• AIt is necessary to confirm the local available channels with the customer before planning
• BSame as the channel of the signal sent by the antenna connected to the indoor AP
• CHuawei's indoor distribution AP6310 supports channel planning for both 2.4G and 5G frequency
• DAdjacent edge antennas do not use the same channel

• A
  3% (2)
• B
  7% (5)
• C
  80% (56)
• D
  10% (7)

Explanation

Option C is wrong because the Huawei AP6310 is a single-band indoor distribution AP that only supports the 2.4GHz frequency band - it does not support 5GHz channel planning. Claiming it handles both bands is the false statement the question is testing.

The distractors are all correct practices: A is true because available channels vary by country/region due to regulatory rules, so customer confirmation is essential before planning. B is true because the indoor antenna must operate on the same channel as the AP feeding it - signal continuity requires channel alignment. D is also true: adjacent edge antennas must use different (non-overlapping) channels to avoid co-channel interference, which is a fundamental principle of WLAN channel reuse design.

Memory tip: Associate the AP6310 with "3" → think three letters in "old" → it's an older, simpler, single-band (2.4GHz only) device. Newer dual-band Huawei APs have higher model numbers (e.g., AP6050DN, AP7050DE). When you see a low-numbered indoor distribution AP in an exam question claiming dual-band support, that's your red flag.
