Intelligent transport systems — Communications access for land mobiles (CALM) — Infra-red systems

ISO 21214:2015 determines the air interface using infrared systems at 820 nm to 1 010 nm.

The International Standard provides protocols and parameters for medium range and medium to high speed wireless communications in the ITS sector using infrared systems.

Such links are required for quasi-continuous, prolonged, or short communications between the following:

- vehicles and the roadside;

- between vehicles;

- 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 made use 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 DSRC.
