IEEE 802.11be (Wi-Fi 7)

- [Narrator] At the time of this recording, the newest Wi-Fi standard is Wi-Fi 7, also known as IEEE 802.11be. That was released in 2024, and like Wi-Fi 6E, the Wi-Fi 7 standard supports the 2.4 gig, the 5 gig, and the 6 gig bands. But the maximum theoretical bandwidth is significantly improved from 9.6 gigabits per second, all the way up to 46 gigabits per second. Now, that's if we're using something called MLO, or Multi-Link Operation. That feature allows us to transmit a signal across all three bands at the same time. However, if we're just using the 6 gig band, then the maximum theoretical bandwidth is 23 gigabits per second. And one of the enhancements to Wi-Fi 7 that helps give us this increased bandwidth is its use of 4,096 QAM. That can encode 12 bits in a single waveform, compared to 10 bits with 1,024 QAM used by Wi-Fi 6 and Wi-Fi 6E. And Wi-Fi 7 has a maximum channel width of 320 megahertz, and it doubles the number of spatial streams that were available in Wi-Fi 6 and…
