Different Types

Different versions of the 802.11 standard have been released over the years, often indicated by a letter following the designation. Wireless-G, for example, introduced numerous improvements over the initial standard such as higher transfer rates. It is important for a computer or device user to recognize what type of WiFi their device uses, to ensure compatibility with the router creating a hotspot. As the technology continues to improve, additional designations are likely to be released, though they are often backwards compatible with earlier versions.
