Curriculum Overview ► What is a wireless LAN? ü Provides all the features and benefits of traditional LAN technologies such as Ethernet without the limitations of wires or cables ü A WLAN, just like a LAN, requires a physical medium through which transmission signals pass. Instead of using twisted-pair or fiber-optic cable, WLANs use infrared light (IR) or radio frequencies (RFs). 3
