Carrier Sense Multiple Access

Carrier Sense Multiple Access is a media access technique used in a number of network technologies.

• The ALOHAnet wireless network used pure Carrier Sense Multiple Access
• Original shared-ether Ethernet uses Carrier Sense Multiple Access with Collision Detection (CSMA/CD)
• IEEE 802.11 uses Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA)
