Because the wireless medium is shared among all devices, there must be rules for cooperation among the wireless devices. The 802.11 standard uses a procedure known as Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA). CSMA/CA attempts to prevent multiple wireless devices from transmitting at the same time. It does this by requiring that all devices wait a random amount of time after a transmission is completed and the medium is clear.
