Detailed explanation-1: -6. Which of the following is the 802.11 High Rate Standard? Explanation: IEEE 802.11b was a high rate standard approved in 1999. It provided new data rate capabilities of 11 Mbps, 5.5 Mbps in addition to the original 2 Mbps and 1 Mbps user rates of IEEE 802.11.
Detailed explanation-2: -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-3: -802.11b. 802.11b used the same 2.4 GHz frequency as the original 802.11 standard. It supported a maximum theoretical rate of 11 Mbps and had a range up to 150 feet.
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.
