Wi-Fi 5 vs. Wi-Fi 6
Comparing 2 standards across 12 specifications. 11 key differences identified.
Wi-Fi 5 (IEEE 802.11ac) was ratified in 2013, operating exclusively in the 5 GHz band. It introduced 80 MHz and 160 MHz channel bonding, 256-QAM modulation, and multi-user MIMO (MU-MIMO) downlink, reaching theoretical maximum data rates up to 6.93 Gbps.
Wi-Fi 6 (IEEE 802.11ax) was ratified in 2021, operating across both 2.4 GHz and 5 GHz bands. Engineered for high-density network efficiency, it introduced Orthogonal Frequency-Division Multiple Access (OFDMA), bi-directional MU-MIMO, 1024-QAM, and Target Wake Time (TWT), reaching physical rates up to 9.6 Gbps.
