Wi-Fi 6 vs. Wi-Fi 6E
Comparing 2 standards across 16 specifications. 15 key differences identified.
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.
Wi-Fi 6E is an extension of the IEEE 802.11ax (Wi-Fi 6) standard into the unlicensed 6 GHz frequency band (5.925–7.125 GHz). It provides up to 1,200 MHz of additional contiguous spectrum, unlocking 14 extra 80 MHz or 7 extra 160 MHz channels completely free from legacy interference and radar DFS restrictions.
