Which 802.11 PHY layer feature allows Wi-Fi 6 (802.11ax) to efficiently serve multiple clients simultaneously on both uplink and downlink?
Correct Answer: B
OFDMA (Orthogonal Frequency Division Multiple Access)is one of the core features introduced inIEEE 802.11ax (Wi-Fi 6). It divides a channel into smaller subcarriers calledResource Units (RUs), allowing an AP to communicate with multiple clients simultaneously, both on uplink and downlink. According to theRUCKUS One Online Help - Wi-Fi 6 Features Overview, OFDMA improves spectrum efficiency, reduces latency, and increases throughput in high-density environments. RUCKUS APs such as the R750andR850use OFDMA in coordination withRUCKUS AI's client traffic analysisto allocate resources dynamically. In contrast,MU-MIMOalso supports multi-user communication but only in one direction (downlink for 802.11ac Wave 2, both for 11ax).QAM256enhances modulation efficiency but doesn't enable concurrent multi-client service.
