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: -IEEE 802.11b: The 802.11b standard provides for a maximum transmission speed of 11Mbps. However, devices are designed to be backward-compatible with previous 802.11 standards that provided for speeds of 1, 2, and 5.5Mbps. 802.11b uses a 2.4GHz RF range and is compatible with 802.11g.
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: -802.11b (also referred to as 802.11 High Rate or Wi-Fi) is an IEEE standard and an extension to 802.11 that applies to wireless LAN’s and provides 11 Mbps transmission (with a fallback to 5.5, 2 and 1-Mbps) in the 2.4 GHz band.
Detailed explanation-5: -802.11b (also referred to as 802.11 High Rate or Wi-Fi )–an extension to 802.11 that applies to wireless LANS and provides 11 Mbps transmission (with a fallback to 5.5, 2 and 1 Mbps) in the 2.4 GHz band. 802.11b uses only DSSS.
