Summary:Although the IEEE 802.11 standard has been around since 1997, work
continues to make it more adaptable to the demand for higher data rates
and true wireless flexibility. Until recently, few organizations used
wireless LANs because they cost too much, their data rates were too low,
they posed occupational safety problems because of concerns about the
health effects of electromagnetic radiation, and the spectrum used
required a license. Today, these problems have largely diminished, and
wireless LAN popularity is skyrocketing. Wireless LANs must meet
requirements typical of any LAN. They must also meet requirements
specific to their intended environment. IEEE 802.11 defines several
services that the wireless LAN must provide if its usefulness is to
match the functionality inherent in wired LANs. IEEE 802.11 is poised to
have a significant impact on the LAN marketplace. As the demand for
mobility and freedom from wiring requirements increases, the standard
offers a comprehensive yet flexible approach to wireless LAN products
