A system administrator is reviewing legacy and modern wireless standard deployments across an enterprise campus. Match each IEEE 802.11 wireless standard on the left to its correct technical specification on the right.
- IEEE 802.11bOperates exclusively at 2.4 GHz with a maximum theoretical speed of 11 Mbps using DSSS.
- IEEE 802.11gOperates exclusively at 2.4 GHz with a maximum theoretical speed of 54 Mbps using OFDM.
- IEEE 802.11n (Wi-Fi 4)Supports dual-band operation (2.4 GHz / 5 GHz) and introduced Multiple-Input Multiple-Output (MIMO) technology.
- IEEE 802.11ax (Wi-Fi 6)Supports dual-band (and 6 GHz for Wi-Fi 6E) operation using Orthogonal Frequency-Division Multiple Access (OFDMA) for high-density efficiency.
Answer
IEEE 802.11b matches the 11 Mbps / 2.4 GHz / DSSS specification; IEEE 802.11g matches the 54 Mbps / 2.4 GHz / OFDM specification; IEEE 802.11n matches the dual-band / MIMO specification; IEEE 802.11ax matches the dual-band (with 6 GHz option) / OFDMA specification.
Each 802.11 standard defines unique operating frequencies, modulation methods, and maximum theoretical throughput rates. 802.11b delivers up to 11 Mbps on 2.4 GHz; 802.11g provides up to 54 Mbps on 2.4 GHz using OFDM; 802.11n introduces dual-band capability alongside MIMO technology; and 802.11ax incorporates OFDMA to increase client capacity across 2.4 GHz, 5 GHz, and 6 GHz spectrums.
