Wi-Fi 6E vs. Wi-Fi 7
Comparing 2 standards across 15 specifications. 15 key differences identified.
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.
Wi-Fi 7 (IEEE 802.11be, Extremely High Throughput) was approved by IEEE-SA in 2024, operating across 2.4 GHz, 5 GHz, and 6 GHz bands. It features 320 MHz channel bandwidth, 4096-QAM modulation, 8x8 MU-MIMO (an early draft's 16 spatial streams was dropped before finalization), and Multi-Link Operation (MLO), achieving theoretical speeds up to about 23 Gbps in a single band.
