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 linked by a wireless router or a wireless access point.
NOTE
●
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
(provided through a service provider or a public or corporate network).
Computers with WLAN devices may support one or more of four IEEE physical layer 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.
