ABSTRACT
The IEEE® 802.11 standard [16] was designed to allow wireless transmissions of data in local area networks. The standard specified the data link and physical layers to be used in such networks. When it was first published, wireless networks were rare. However, recent years have seen drastic increases in popularity of wireless technologies in general and in the deployment of 802.11-based networks in particular. Today, 802.11, with various updates to the physical-layer specification, is the most popular communication mechanism for wireless networks.
