In most wired and wireless networks, the Medium Access Control rules describe the methods which are used to determine when and how a device can transmit data over the communications link. This is the network’s Medium Access Control scheme. The MAC sublayer and protocols operate within the Data Link layer - Layer 2 of the ISO OSI 7 layer model. The IEEE 802.11 standard, for example, specifies the MAC protocol for sharing of wireless medium, constructing frames, addressing, error detection and recovery following errors.
