In this module, we discuss some of the media access control (MAC) and Physical Layer characteristics of wireless LANs that are common to all wireless LAN products, regardless of the manufacturer. We also explain the difference between Ethernet and wireless LAN frames and how wireless LANs avoid collisions.
