FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -8. Which of the following WLAN standard has been named Wi-Fi? Explanation: The DSSS IEEE 802.11b standard has been named Wi-Fi by the Wireless Ethernet Compatibility Alliance.

Detailed explanation-2: -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-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.

Detailed explanation-4: -There are several standards of IEEE 802.11 WLANs. The prominent among them are 802.11, 802.11a, 802.11b, 802.11g, 802.11n and 802.11p. All the standards use carrier-sense multiple access with collision avoidance (CSMA/CA). Also, they have support for both centralised base station based as well as ad hoc networks.

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.
