Frequency speed
- [Instructor] Here we can see the Wi-Fi frequency standards over the years from the time it was first developed in 1997. You can see underneath the standard, they all start with 802.11. That basically means 1980 for the 80, and the number two stands for February, and the 11th is the 11th paper that was ratified by the IEEE, or International Electrical Institute. So they're always going to start with 802.11 when it comes to Wi-Fi. And the frequency band started out at 2.4 gigahertz and mostly stayed there for quite a long time until we finally started using 5 gigahertz. Now, we can see, as of 2023, 802.11be, which is what we're using for Wi-Fi 7, will run at 2.4, 5, and 6-7 gigahertz, as well. It officially says that it's going to run at 6 gigahertz by the IEEE, but it does bleed in to just over 7 gigahertz when tested. You can also see where it says Bandwidth, and it starts out at 20 megahertz, and then it starts creeping up all the way to 320 megahertz in 2023 with Wi-Fi 7. And what…
