标准简介：This International Standard determines the air interface using infra-red systems at 820 nm to 1 010 nm.
It provides protocols and parameters for medium-range, medium- to high-speed wireless communications in
the ITS sector using infra-red systems.
Such links are required for quasi-continuous, prolonged or short communications
⎯ between vehicles and the roadside,
⎯ between vehicles, and
⎯ between mobile equipment and fixed infrastructure points,
over medium and long ranges.
Vehicles may be moving or stationary.
Wherever practicable, this International Standard has been developed by reference to suitable extant
International Standards, adopted by selection. Required regional variations are provided.
Due account is given to, and use made of, any relevant parts of appropriate communications systems, such
as global positioning systems (GPS), digital audio broadcasting (DAB), digital video broadcasting (DVB), radio
local area networks (RLANs), digital data broadcasting (DDB), TETRA, FM subcarrier, mobile broadband
systems (MBS, W-ATM), internet protocols, and dedicated short range communication (DSRC).
The International Standard:
⎯ supports data rates of 1 Mbit/s up to 128 Mbit/s (it may support higher data rates);
⎯ supports vehicle speeds up to a minimum of 200 km/h (closing speeds could be double this value);
⎯ defines or references environmental parameters relevant to link operation;
⎯ supports communication distances up to 100 m (it may support longer communication distances of 300 m
to 1 000 m);
⎯ supports latencies and communication delays in the order of milliseconds;
⎯ is compliant to regional/national regulatory parameters;
⎯ may support other regional/national parameters as applicable.
Application-specific requirements are outside the scope of this International Standard. These requirements will
be defined in the CALM management and upper layer standards and in application standards.
Application-specific upper layers are not included in this International Standard, but will be driven by application standards (which may not be technology specific).
