A city warehouse Wi-Fi 6 deployment supports many handheld scanners and softphones exchanging frequent small frames under load. Which HE feature most directly improves efficiency for that traffic pattern?
Select an answer to reveal the explanation.
Short Explanation
Lots of tiny scanner beeps used to wait in one long line for the whole channel. OFDMA splits the channel into mini-lanes so many small frames ride together. That’s why Wi-Fi 6 helps dense low-rate IoT/voice loads.
Full Explanation
OFDMA allocates subsets of the channel (resource units) so multiple stations transmit or receive small frames concurrently under AP scheduling. That concurrency cuts the contention overhead typical of many short scanner and softphone transactions on a busy warehouse SSID. Forcing DSSS, disabling MU/OFDMA, or mandating 160 MHz for handhelds works against dense small-frame efficiency and spatial reuse. Expert validation should confirm HE clients actually receive RU schedules under load rather than falling back to inefficient single-user contention.
