This standard describes multi-channel wireless radio operations, WAVE mode, medium access control (MAC) and physical layers (PHYs), including the operation of control channel (CCH) and service channel (SCH) interval timers, parameters for priority access, channel switching and routing, management services, and primitives designed for multi-channel operations. To enable effective mechanisms that control the operation of upper layer across multiple channels, without requiring knowledge of PHY parameters, and describe the multi-channel 1 operation channel routing and switching for different scenarios. New IEEE Standard - Inactive-Withdrawn. Multi-channel operation is an extension to the IEEE 802.11 WAVE mode that describes how to support a multi-channel system with the IEEE 802.11 medium access control (MAC) and physical layers (PHYs) via a control channel (CCH) and multiple service channels (SCHs). Specifically, the multi-channel operation (channel coordination) provides mechanisms for prioritized access, channel routing and coordination, and data transmission.
