Course 2206 Wireless Telecommunications Lesson 9. Wi-Fi: 802.11 Wireless LANs.
In this lesson, we provide an overview of the 802.11 wireless LAN standards, Wi-Fi and hotspots. We concentrate on understanding the variations of 802.11, the frequency bands they operate in, bit rates to be expected, propagation issues, and Wi-Fi 6, which is 802.11ax, the first to implement OFDMA.
Wireless Telecommunications is a comprehensive up-to-date course for non-engineering professionals on wireless, including radio fundamentals, cellular and mobile telecommunications, LTE, 5G, Wi-Fi and satellites for non-engineering professionals.
Taking this course, you will develop a solid understanding of the fundamental principles of radio, mobility and cellular, network components and operation, digital radio, mobile phone calls and mobile Internet access, spectrum-sharing technologies like OFDM, and LTE and 5G. In addition, you will get up to speed on the components, operation and latest standards for Wi-Fi, and the essentials of satellite communications.
We'll cut through the jargon to demystify wireless, explaining the fundamentals of cellular and mobility, the buzzwords, the network, technologies and generations, the underlying ideas, and how it all works together... in plain English.

Since 802.11 is wireless LANs, there are a number of associated topics: LAN frames, also called MAC frames, MAC addresses, LAN switches, IP addresses, routers and network address translation. Those topics are covered in other courses, particularly “Ethernet, LANs and VLANs”, “Introduction to Datacom and Networking” and “IP Networks, Routers and Addresses”. In this course, we concentrate on radio.
