Since Wi-Fi was first released to consumers in 1997, Wi-Fi standards have been continually evolving – typically resulting in faster speeds and further coverage. With every new capability comes a name change to set the standards apart. As capabilities are added to the original IEEE 802.11 standard, they become known by their amendment (802.11b, 802.11g, etc.).
