Working with Wireless LANs
Wireless LANs are built upon the 802.11 family of standards and operate in a similar manner to wired networks. The difference between the two—beyond the obvious lack of wires—is the fundamental functioning of the network itself.
CSMA/CD Versus CSMA/CA
One of the big differences between wired and wireless technologies is the way signals are transmitted and received on the network. In networks based on the Ethernet standard (802.3), stations transmit their information using the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) method. Networks that use this method have stations that transmit their information as needed, but collisions are possible when two stations transmit at the same time.
