A network technician is updating documentation for a company's wireless infrastructure. Match each IEEE 802.11 wireless standard to its defining frequency band, maximum theoretical throughput, and core technical feature.
- IEEE 802.11aOperates exclusively in the 5 GHz band at up to 54 Mbps using OFDM modulation.
- IEEE 802.11gOperates in the 2.4 GHz band at up to 54 Mbps while maintaining backward compatibility with 802.11b.
- IEEE 802.11acOperates exclusively in the 5 GHz band, introducing downlink MU-MIMO and support for 160 MHz channel bonding.
- IEEE 802.11axOperates across the 2.4 GHz, 5 GHz, and 6 GHz bands, introducing OFDMA for improved high-density client efficiency.
Answer
IEEE 802.11a matches 5 GHz operation at 54 Mbps using OFDM; IEEE 802.11g matches 2.4 GHz operation at 54 Mbps with 802.11b compatibility; IEEE 802.11ac matches 5 GHz-only operation with downlink MU-MIMO and 160 MHz channel bonding; IEEE 802.11ax matches multi-band operation (2.4/5/6 GHz) utilizing OFDMA.
Each standard is accurately paired based on its operating frequencies, maximum theoretical data rates, and characteristic features such as OFDM, MU-MIMO, or OFDMA.
