IEEE 802.11ac (Wi-Fi 5)
- [Instructor] In our previous video, we took a look at some of the characteristics of the IEEE 802.11n standard. Now let's contrast that with the 802.11 ac standard, which is also known as Wi-Fi 5. 802.11 ac came out about five years after the .11n standard, being released in 2014. And one big difference is that IEEE 802.11 ac only operates in the five gigahertz band. It doesn't use the 2.4 gigahertz band at all. And its maximum bandwidth is significantly higher, at 3.5 gigabits per second. And that's due in part to its ability to represent eight bits with a single wave form. It does that using 256 QAM. And we can combine a couple of our 20 megahertz channels into a single 40 megahertz channel. Or we could combine four of those regular channels into an 80 megahertz channel. Or on some equipment, not all, but on some equipment, we can combine eight of those 20 megahertz channels into a single 160 megahertz channel. And…
