WLAN optimization and features

- [Instructor] In this video, let's discuss some optimization features for wireless LANs, beginning with channel bonding. As we discussed previously, we often work with a channel width of 20 megahertz and that can be divided into 10 sub channels, because we can represent binary data for a stream in a single sub channel. But if I want to support more than 10 sub channels to support more than 10 different conversations going on in this wireless access point, what I could do is bond together a couple of 20 mhz channels into a single 40 mhz channel. This is called channel bonding. If I bond four of those 20 megahertz channels together, I get a single 80 megahertz channel. And if I bond eight of those 20 megahertz channels together, that gives me a very large 160 megahertz channel. And as a reference, let's build on the table we saw in a previous video discussing QAM, and see what supported channel widths we have for different…
