With the 802.11 wireless device, you can access a wireless local
area network (WLAN), which is composed of other computers
and accessories linked by a wireless router or a wireless access
point.
■ A large scale WLAN, such as a corporate WLAN or public
WLAN hotspot, typically use wireless access points, that can
handle a large number of computers and accessories and can
separate critical network functions.
■ A home or small office WLAN typically uses a wireless
router, which enables several wireless and wired computers to
share an Internet connection, a printer, and files without
additional pieces of hardware or software. Wireless access
point and wireless router are often used interchangeably.
Notebooks with 802.11 WLAN devices may support one or more
of 3 IEEE physical layer standards:
■ 802.11a
■ 802.11b
■ 802.11g
