Over deze norm
This International Standard is part of a family of standards for communications access for land mobiles (CALM) which determine a common architecture, network protocols and air interface definitions for wireless communications using a range of communication bearers, such as Cellular 2nd Generation, Cellular 3rd Generation, microwaves, millimetre waves and Infrared light. Other air interfaces may be added at a later date. These air interfaces are designed to provide parameters and protocols for broadcast, point-point, vehicle-tovehicle, and vehicle-point communications for intelligent transport systems (ITS) applications. This International Standard provides specifications for the PHY part of a communications interface for systems operating within the millimetre frequency range of 57 GHz to 66 GHz. This communications interface (referred to as CALM MM) is designed to provide up to medium range, medium-to-high speed wireless communications links in the ITS sector. Such communication links are required for quasi-continuous, brief or prolonged communications between - vehicles and the roadside communication infrastructure, and - vehicles. Vehicles can be moving or stationary. 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.
