IEEE 802.11b Wireless LAN
Wireless communication occurs over radio waves rather than a wire. Like a cordless telephone, a wireless
LAN uses radio signals instead of wires to exchange data. A wireless network eliminates the need for
expensive and intrusive wiring to connect computers throughout the home or office. Mobile users can remain
connected to the network even when carrying their laptop to different locations in the home or office.
Each computer on a wireless LAN requires a wireless adapter.
