The development of technology and applications has promoted the arrival of the Wi-Fi6 era. Which of the following descriptions of the high performance of Wi-Fi6 are correct? (Multiple choice)

Question

Options

• AEach AP can access 1024 terminal devices
• BThe average delay can be reduced by 25%
• CThe rate can be as high as 9.6 Gbps
• DWireless delay can be as low as 1.5ms

• A
  74% (25)
• B
  9% (3)
• D
  18% (6)

Explanation

Wi-Fi 6 (802.11ax) officially supports up to 1,024 associated devices per access point (option A), enabled by technologies like Target Wake Time (TWT) and BSS Coloring, and achieves a theoretical maximum throughput of 9.6 Gbps (option C) through 8-stream OFDMA and 1024-QAM modulation.

Option B is wrong because Wi-Fi 6 reduces average latency by 75%, not 25% - a much more dramatic improvement than the distractor suggests.

Option D is wrong because the 1.5ms figure is not a standard Wi-Fi 6 specification; typical Wi-Fi 6 latency targets are around 10ms or less - sub-2ms latency is more characteristic of wired or 5G Ultra-Reliable Low Latency (URLLC) connections.

Memory tip: Remember Wi-Fi 6's headline numbers as "1024 and 9.6" - 1,024 devices and 9.6 Gbps. For latency, think "75% reduction" (not 25%), and be suspicious of any latency claim below ~10ms for wireless - that's the realm of wired networks, not Wi-Fi.
