ISO 21216:2012-Intelligent transport systems - Communication access for land mobiles (CALM) - Millimetre wave air interface
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.
