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.

Setting up a WLAN

To set up a WLAN and connect to the Internet, you need the following equipment:

A broadband modem (either DSL or cable) (1) and high-speed Internet service purchased from an Internet service provider (ISP)

A wireless router (purchased separately) (2)

The wireless computer (3)

The illustration below shows an example of a wireless network installation that is connected to the Internet.

As your network grows, additional wireless and wired computers can be connected to the network to access the Internet.

For help in setting up your WLAN, refer to the information provided by your router manufacturer or your ISP.
