scope:

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.

Purpose

To enable effective mechanisms that control the operation of upper layer across multiple channels, without requiring knowledge of PHY parameters, and describe the multi-channel¹ operation channel routing and switching for different scenarios.

¹A channel is defined as a physical channel specified in IEEE Std 802.11, as amended by IEEE P802.11p™ . WAVE devices may implement a multi-channel or multi-radio capability in future standards or non-standardized implementations. Multi-radio/channel implementations are permitted, but are outside the scope of this standard.
