Intelligent transport systems. Communication access for land mobiles (CALM). Millimetre wave air interface Ingestion-build-181247 Small areas of surface dressing1 Scope 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)
