Wi-Fi standards are guidelines that define how wireless networks operate, ensuring devices can communicate effectively. These standards are developed by the Institute of Electrical and Electronics Engineers (IEEE) and are designated with the letter "802.11," followed by a letter or number indicating the specific version, such as 802.11ac or 802.11ax. Each Wi-Fi standard offers different speeds, ranges, and capabilities. For example, 802.11n introduced multiple antennas for better performance, while 802.11ax, also known as Wi-Fi 6, improves efficiency in crowded areas. Understanding these standards helps users choose the right equipment for their needs.
