The work of preparing International Standards is normally carried out through ISO technical com
11、mittees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
12、 International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft Internationa
13、l Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the
14、subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 21216 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems.This second edition cancels and replaces the first edition (ISO 21216:2011), which has been technically re
15、vised.iv ISO 2012 All rights reservedBS ISO 21216:2012ISO 21216:2012(E)IntroductionThis 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 commun
16、ications 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-po
17、int, vehicle-to-vehicle, 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 comm
18、unications 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
19、 infrastructure, and vehicles.Vehicles can be moving or stationary.Wherever practicable, this International Standard has been developed by reference to suitable existing standards, adopted by selection. Required regional variations are provided for.ITS applications which can be enhanced or are enabl
20、ed by the CALM architecture and media include car-to-car and point-to-multipoint safety messaging, collision avoidance, the update of roadside telemetry and messaging, probe data collection, general internet access, image and video transfer, infotainment, traffic management, monitoring and enforceme
21、nt in mobile situations, route guidance, maintenance management, and “yellow pages” services.The millimetric frequency band is suitable for applications which require the transfer of a large quantity of data, or of combinations of applications which together require a high data transfer because they
22、 need to be able to coexist.This International Standard recognizes that frequency allocations in the millimetric range around 60 GHz differ in different parts of the world. In Europe (ITU Region 1), the band 63 GHz to 64 GHz has been designated for ITS applications, while in some countries in ITU Re
23、gions 2 and 3 ITS applications can take place within the wider range of 57 GHz to 66 GHz, in which a variety of generic application types is allowed. The emission limits vary among regions or countries. A frequency band specifically designated for ITS applications is not required in order to impleme
24、nt this International Standard.Because of these variations, this International Standard describes the physical layer parameters which need to be standardized to characterize the air interface. This description will enable equipment to be designed which has functional interoperability in the same cou
25、ntry or region, but which will have detailed parameters limited in accordance with the appropriate national standards. It also describes those parameters characterizing the operation of the radio which are needed for interfacing to the CALM architecture, in accordance with ISO 21218. ISO 2012 All ri
