Wi-Fi 7 will also be known as 802.11be, just like Wi-Fi 6 to 802.11ax, or Wi-Fi 5 to 802.11ac, and so on. It's much easier to remember that 7 comes after and is “better” than 6. Like all previous Wi-Fi standards, Wi-Fi 7 will be backward compatible. The Wi-Fi Alliance has announced the certification for Wi-Fi 6E, or Wi-Fi 6 Extended, which refers to the ability for Wi-Fi to leverage the 6 GHz band for unlicensed Wi-Fi operation. But, even as the industry rejoices in Wi-Fi receiving additional spectrum for the first time in 20 years, the next generation of wireless technology is already on the horizon, promising even higher data rates and lower latency.
When compared to Wi-Fi 6, Wi-Fi 7 ( or 802.11be) will also use multi-band/multi-channel aggregation and operation and deliver higher spectrum and power efficiency, better interference mitigations, higher capacity density and higher cost efficiency. The seventh generation of Wi-Fi is also referred to as Wi-Fi Extremely High Throughput as result of its projected ability to support up to 30Gbps throughput, roughly three times faster than Wi-Fi 6.
There are a number of proposed features for the Wi-Fi 7 standard, but direct enhancements over Wi-Fi 6 include support of 320 MHz transmissions, which is double the 160 MHz of 802.11ax, the use of higher modulation orders, optionally supporting 4096-QAM — up from 1024-QAM in 802.11ax — and the allocation of multiple resource units, such as groups of OFMDA tones.
Wi-Fi 7 will utilize the 2.4 GHz (2.400 to 2.495 GHz), 5 GHz (5.170 to 5.835 GHz) and 6 GHz (5.925 to 7.125 GHz) frequency bands and aims to support a transmission rate of up to 30 Gbps, which is more than three times the maximum rate for Wi-Fi 6/6E (9.6 Gbps).
