802.11b (formally known as IEEE 802.11b-1999) is a Wi-Fi protocol that operates in the 2.4GHz band. It was used by most of the first generation wireless access points. 802.11b has data rates between 1.5 and 11Mbit/s. Most modern access points that work on the 2.4GHz still to support this as a legacy prtocol, whilst providing 802.11n as the prefered protocol.
