Detailed explanation-1: -IEEE 802.11b: The 802.11b standard provides for a maximum transmission speed of 11Mbps.
Detailed explanation-2: -802.11b uses DSSS (Direct-Sequence Spread Spectrum)-a modulation method used to reduce signal interference-in the 2.4 GHz band, allowing it to have speeds up to 11 Mbps.
Detailed explanation-3: -Also called Wi-Fi, 802.11b operates at 2.4 GHz with a maximum transmission rate of 11M bit/sec. at the access point (AP). Meanwhile, 802.11a operates on the less-crowded 5-GHz band and runs at up to 54M bit/sec.
Detailed explanation-4: -IEEE 802.11b is an amendment to the 802.11 standard for wireless LANs. It is of of the specifications that is more commonly known as Wi-Fi. 802.11b uses the same unregulated radio frequency band of 2.4 GHz that was used by the original 802.11 standard, but operates at theoretical data throughput of 11 Mbps.
