Wireless Networks
In this video, we cover the fundamentals of wireless networks, starting with an introduction to electromagnetic waves and how they carry data over the air using radio frequencies (RF). We explain the basic concepts of RF, including the available frequency bands commonly used for wireless computer networks, such as the 2.4 GHz and 5 GHz bands. The video also discusses the key IEEE standards that define wireless communications, like 802.11, and explores essential concepts like Basic Service Set (BSS) and Extended Service Set (ESS), which are fundamental to how wireless networks are structured and managed.
