Due to increased demand for convenient networking and more flexible access to both
the Internet and company resources via more geographically widespread coverage areas,
wireless networking use has increased dramatically in recent years. Mobile access to data
services previously unavailable is now common. The sales and penetration of wireless
access have resulted in a recent projection by <ulink

Wi-Fi chipsets <ulink

- Not only has wireless data access achieved a great deal of market penetration in
recent years, but the price of the related hardware has dropped dramatically, making it
even more accessible. Wi-Fi seems to be everywhere; in laptops, desktops, PDAs, cell
phones and routers, and there is such a large amount of wireless networks in many urban
areas that complete overcrowding of the public wireless radio spectrum in use can occur.

802.11 wireless networking standards, concepts, hardware components, security concerns,
and their relation to &PRODUCT; Linux. Although the specific wireless technology based
on IEEE 802.11 is the primary focus of this guide, other mobile technologies and their
relation to &PRODUCT; and Linux are also mentioned. Parts of this guide contain
detailed information specific to &PRODUCT; and other Linux operating systems, however,
many of the topics and concepts relate to all operating systems, vendors, and
environments.

A wireless LAN (referred to as WLAN in this guide) is a wireless local area network
that allows computers or other devices to communicate via radio frequency (RF) technology.
It affords the user mobility to move around and stay connected to the network without
using physical cables such as in a traditional Ethernet system.

- The IEEE (Institute of Electrical and Electronics Engineers) is a non-profit, global
organization which implemented and continually develops a set of standards for wireless
communication. This family of standards is known as IEEE 802.11 and consists of the actual
standards and protocols defining how computers communicate via a WLAN. Standards are
discussed in more detail later. Although wireless networks are commonly referred to as
Wi-Fi, this is only a marketing term chosen by the Wireless Ethernet Compatibility
Alliance (now known as the Wi-Fi Alliance). When referring to Wi-Fi, the underlying
technology is typically a WLAN or device operating within the standards of the IEEE within
the 802.11 family.
