IEEE 802.11ax (Wi-Fi 6)

- [Instructor] The IEEE 802.11ax wireless standard, also known as Wi-Fi 6, was released in 2019, and it operates on both the 2.4 and the five gigahertz frequency bands, and it has a very fast theoretical maximum bandwidth of 9.6 gigabits per second, and its implementation of 1,024 qualm lets us represent 10 bits in a single waveform. Also, it supports the same channel width options that we saw with .11ac and the number of simultaneous spatial streams that we support has been increased to eight. But what's interesting about this is that this could be a mixture of some upstream and some downstream spatial streams. Another big difference with 802.11ax is its use of OFDMA, orthogonal frequency-division multiple access, as its transmission method, and OFDMA gives us the benefit of the Target Wake Time feature. With this feature, our wireless clients are not contending for access to the airwaves. Instead, they're told when they can transmit, specifically the access point tells the wireless…
