On IEEE 802.11: Wireless LAN Technology

摘要

Network technologies are traditionally based on wireline solutions. But theintroduction of the IEEE 802.11 standards have made a huge impact on the marketsuch that laptops, PCs, printers, cellphones, and VoIP phones, MP3 players inour homes, in offices and even in public areas have incorporated the wirelessLAN technology. Wireless broadband technologies nowadays provide unlimitedbroadband access to users which were previously offered only to wireline users.In this paper, we review and summarize one of the emerging wireless broadbandtechnology i.e. IEEE 802.11,which is a set of physical layer standard forimplementing wireless local area network computer communication in the2.4,3.6,5 and 60GHz frequency band. They fix technology issues or addfunctionality which is expected to be required by future applications. Thoughsome of the earlier versions of these technologies are obsolete (such asHiperLAN) now but still we have included them in this review for the sake ofcompleteness.
