  1. Which 802.11 amendment introduced Multi-User MIMO (MU-MIMO) allowing simultaneous transmission to multiple clients?

    Answer: 802.11ac Wave 2

    802.11ac Wave 2 introduced MU-MIMO, enabling an AP to transmit to multiple clients simultaneously rather than one at a time.

  2. What is the maximum number of spatial streams supported by 802.11ac?

    Answer: 8

    802.11ac supports up to 8 spatial streams, though most consumer devices implement 3 or 4.

  3. A technician needs to deploy Wi-Fi in a high-density stadium environment. Which 802.11ax (Wi-Fi 6) feature most directly addresses this need?

    Answer: OFDMA

    OFDMA (Orthogonal Frequency Division Multiple Access) in Wi-Fi 6 divides channels into sub-channels called Resource Units, allowing many clients to transmit simultaneously.

  4. Which wireless standard operates exclusively in the 60 GHz band and is designed for short-range, high-bandwidth applications?

    Answer: 802.11ad

    802.11ad (WiGig) operates in the 60 GHz band, offering multi-gigabit speeds over very short distances (typically within a room).

  5. What modulation scheme does 802.11ax (Wi-Fi 6) support that 802.11ac does not?

    Answer: 1024-QAM

    Wi-Fi 6 (802.11ax) introduces 1024-QAM, allowing more bits per symbol and higher throughput compared to 802.11ac's maximum of 256-QAM.

  6. A wireless network shows clients connecting at 54 Mbps on the 2.4 GHz band. Which standard is most likely in use?

    Answer: 802.11g

    802.11g operates in the 2.4 GHz band with a maximum data rate of 54 Mbps, matching this scenario.

  7. Which Wi-Fi generation introduced Target Wake Time (TWT) to improve battery life for IoT devices?

    Answer: Wi-Fi 6 (802.11ax)

    Wi-Fi 6 (802.11ax) introduced Target Wake Time, allowing devices to schedule when they wake to send/receive data, significantly improving IoT device battery life.
