Demystifying the 802.11a/b/g Wireless Standard
| sponsored by Xirrus
WHITE PAPER:
This guide will provide an overview of the 802.11a/b/g standard, including a discussion on how these standards compare in regards to bandwidth, available channels, and the impact of interference on each.

802.11B DEFINITION (continued): … The 802.11b standard for wireless local area networks ( WLANs) - often called Wi-Fi - is part of the 802.11 series of WLAN standards from the Institute of Electrical and ElectronicsEngineers ( IEEE). 802.11b is backward compatible with 802.11. Like other 802.11 standards, 802.11b uses the Ethernet protocol and CSMA/CA (carrier sense multiple access with collision avoidance) for path sharing. The modulation used in 802.11 has historically been phase-shift keying (PSK). The modulation method selected for 802.11b is known as complementary code keying (CCK), which allows higher data speeds and is less susceptible to multipath-propagation interference. 802.11b definition sponsored by SearchMobileComputing.com, powered by WhatIs.com an online computer dictionary
