IEEE 802.11ax (Wi-Fi 6)
- At the time of this recording, the newest wireless standard is 802.11ax, also known as Wi-Fi 6. It was released in 2019 and it operates on both the 2.4 and 5 gigahertz bands. It's got a very fast theoretical maximum bandwidth of 9.6 gigabits per second, and its implementation of 1024-QAM lets us represent 10 bits with a single waveform. And it supports the same channel with options that we saw with .11ac. The number of simultaneous spatial streams that we can send out has increased to eight. But in addition to those eight downstream spatial streams, we can also have eight upstream spatial streams. And another big difference with 802.11ax is its use of OFDMA, orthogonal frequency division multiple access, which, as we saw earlier, takes sub-channels and divides them into sub-carriers. Another huge advantage of 802.11ax is its use of the Target Wake Time feature. With this feature, our wireless clients are not contending…
