Detailed explanation-1: -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 (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.
Detailed explanation-4: -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.
