Using WLAN devices (select models

only)

With a WLAN device, you can access a wireless local area network, which is composed of other

computers and accessories that are linked by a wireless router or a wireless access point.

NOTE:

The terms wireless router and wireless access point are often used interchangeably.

●

A large-scale WLAN, such as a corporate or public WLAN, typically uses wireless access points

that can accommodate 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 allows several wireless and

wired computers to share an Internet connection, a printer, and files without requiring additional

pieces of hardware or software.

NOTE:

To use the WLAN device in your computer, you must connect to a WLAN infrastructure

(provided through a service provider or a public or corporate network).

Computers with WLAN devices support one or more of the following IEEE industry standards:

●

802.11b, the first popular standard, supports data rates of up to 11 Mbps and operates at a

frequency of 2.4 GHz.

●

802.11g supports data rates of up to 54 Mbps and operates at a frequency of 2.4 GHz. An 802.11g

WLAN device is backward compatible with 802.11b devices, so they can operate on the same

network.

●

802.11a supports data rates of up to 54 Mbps and operates at a frequency of 5 GHz.

NOTE:

●

802.11n supports data rates of up to 270 Mbps and may operate at 2.4 GHz or 5 GHz, making it

backward compatible with 802.11a, b, and g.
