An alternative physical layer (PHY) and a modified medium access control (MAC) layeris defined in this amendment.Two PHY modes have been defined that enable data rates up to 100 Gb/s using the 60 GHz band. MIMO and aggregation methods have been defined to increase the maximum achievable communication speeds. Stack acknowledgment has been defined to improve the medium access control (MAC) efficiency when used in a point-to-point (P2P) topology between two devices.

This standard defines PHY and MAC specifications for high data rate wireless connectivity (typically over 200 Mbps) with fixed, portable and moving devices. Data rates are high enough to satisfy a set of consumer multimedia industry needs, as well as to support emerging wireless switched point-to-point and high rate close proximity point to point applications

The purpose of this standard is to provide for low complexity, low cost, low power consumption, high data rate wireless connectivity among devices supporting a variety of applications such as a set of consumer multimedia industry needs, wireless switched point-to-point applications in data centers, wireless backhaul/fronthaul intra-device communications and a wide variety of additional use cases such as rapid large multimedia data downloads and file exchanges between two devices in close proximity, including between mobile devices and stationary devices (kiosks, ticket gates, etc.), and/or wireless data storage devices.
