CompTIA A+ Certification Core 1 (220-1101) - Wi-Fi Standards

The video tutorial covers the evolution of the 802.11 wireless networking standards, explaining the original standard and its various extensions like 802.11a, b, g, n, and ac. It discusses the use of ISM bands, specifically the 2.4 GHz and 5 GHz bands, and the concept of channels to avoid interference. The tutorial also highlights the importance of backward compatibility and introduces MIMO technology. Finally, it touches on the Wi-Fi Alliance's new terminology for these standards, such as Wi-Fi 4 and Wi-Fi 5.
