A city Wi-Fi team must prove whether a Wi-Fi 6E client is using multiple spatial streams on 6 GHz during a council-chamber event. What capture-device requirement is most critical?
Select an answer to reveal the explanation.
Short Explanation
You can't photograph a 6 GHz multi-stream dance with a 2.4 GHz disposable camera. The sniffer has to speak the same PHY, band, and streams you're judging. Match the tool to the exam you're giving the air.
Full Explanation
Over-the-air protocol analysis is constrained by the capture adapter's supported bands, PHYs, channel widths, and spatial streams. Proving Wi-Fi 6E/7 behavior requires a sniffer that can receive those PPDUs; older single-band adapters and wired SPAN mirrors cannot substitute for missing HE/EHT air headers. Device selection is therefore a first-order CWAP/CWNE methodology decision before interpreting MCS or MU/OFDMA evidence.
