Wireless Local Area Network (Select

Models Only)

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 uses 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 wireless devices may support one or more

of three IEEE physical layer standards:

■ 802.11a

■ 802.11b

■ 802.11g

There are three popular implementations of WLAN adapters:

■ 802.11b only

■ 802.11b/g

■ 802.11a/b/g
