Wireless (Select Models Only) 802.11 Wireless Devices (Select Models Only) A computer with an 802.11 wireless device can access a wireless local area network (commonly referred to as wireless network, wireless LAN, or 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 or public WLAN, 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. ✎ The terms wireless access point and wireless router are often used interchangeably. ■ Computers with 802.11 wireless devices may support 1 or more of 3 industry standards: ❏ 802.11b, 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. ✎ 802.11a is not compatible with 802.11b and 802.11g.
