Free CCNA | Wireless Fundamentals | Day 55 | CCNA 200-301 Complete Course

Welcome to Jeremy’s IT Lab. This is a free, complete course for the CCNA. If you like these videos, please subscribe to follow along with the series. Also, please like and leave a comment, and share the video to help spread this free series of videos. Thanks for your help. In this video we’ll take a look at the fundamentals of wireless networks.

The exam topics we will cover are 1.1.d, access points, 1.11.a, nonoverlapping wi-fi channels, 1.11.b, SSID, and 1.11.c, RF. We will cover these and other wireless exam topics in greater depth in future videos, but this video will be a general overview and introduction to wireless networks. Here’s what we’ll cover in this video. I’ll introduce radio frequency, RF.

RF is a range of electromagnetic wave frequencies which have been assigned for various purposes, including AM and FM radio, microwaves, radar, and Wi-Fi. The last one is of most interest to us, of course, because wireless LANs use Wi-Fi. I’ll talk about Wi-Fi standards as defined in IEEE 802.11. Just like various Ethernet standards are defined in IEEE 802.3, various wireless LAN standards

are defined in IEEE 802.11. We’ll look at some fundamentals of wireless LANs and how they differ from wired LANs. We’re going to cover a lot of new concepts in this video, so I highly recommend taking notes as you watch. When learning new concepts taking notes is important to help you keep the new information

organized without feeling overwhelmed. Make sure to watch until the end of the video for a bonus practice question from Boson Software’s ExSim for CCNA, my recommended practice exams for the CCNA. First let me introduce wireless networks, specifically wireless LANs. Although we will briefly look at other types of wireless networks, in this section of the
