Detailed explanation-1: -802.11b. The 802.11b standard has a maximum raw data rate of 11 Mbit/s (Megabits per second) and uses the same media access method defined in the original standard. 802.11b products appeared on the market in early 2000, since 802.11b is a direct extension of the modulation technique defined in the original standard.
Detailed explanation-2: -IEEE 802.11b: The 802.11b standard provides for a maximum transmission speed of 11Mbps.
Detailed explanation-3: -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. 801.11.
Detailed explanation-4: -IEEE 802.11b (WiFi 1) 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.
