In the previous video we looked at various fundamental concepts of wireless networking, but in this video we’ll look at some more specifics, specifically wireless architectures. By architectures, I mean how the wireless network fits in to the greater picture of the network as a whole, including the wired network infrastructure. We’ll cover exam topic 1.1d,

access points, 1.1.e, controllers, as well as 2.6, 2.7, and 2.8. Here’s what we’ll cover. Before covering wireless architectures, we’ll take a quick look at 802.11 messages and the 802.11 frame format. 802.11 wireless LANs function differently than 802.3 wired Ethernet LANs, so there are some unique message types and the frame format is different as well. Then we’ll cover different wireless access point architectures. Autonomous,

lightweight, and cloud-based. Finally we’ll look at different wireless LAN controller deployments. We didn’t cover WLCs in the previous video. They are used to centrally manage and control access points, and are essential in large networks which can have hundreds or even thousands of wireless access points. Make sure to watch until the end of the video

for a bonus question from Boson Software’s ExSim, the best practice exams for the CCNA. So let’s look at the 802.11 frame format first. As you can see, it has a different format than an 802.3 Ethernet frame. 802.11 frames are more complicated than ethernet frames, but for the CCNA you don’t have to learn it in as much detail as the Ethernet and IP headers. So,
