This International Standard covers the open systems interconnection (OSI) Layer 1 physical layer (PHY) air interface for a communications medium operating in the 60 GHz millimetric frequency range by providing the parameters for medium range, medium-to-high speed wireless communications in the ITS sector. It specifies the parameters required to interface the Layer 1 of such a system to the communications access for land mobiles (CALM) architecture.Application-specific requirements are not included in this International Standard. These requirements are defined in the CALM management and upper layer standards, including the CALM application management International Standard, ISO 24102.
