IEEE 802.11 provides high bandwidth connectivity in a Local Area Network (LAN) environment that is suitable for most data applications. Wireless LAN (WLAN, also known as Wi-Fi) is a set of low tier, terrestrial, network technologies for data communication. It is called 802.11 after the name of the group formed to oversee its development. Unfortunately, 802.11 only support a maximum network bandwidth of 2 Mbps - too slow for most applications. For this reason, ordinary 802.11 wireless products are no longer manufactured.
