ISO 25112:2010 selects the options appropriate for CALM using mobile wireless broadband (MWB) techniques conforming to IEEE 802.16, and specifies the management interface requirements.
CALM links are required for quasi-continuous, prolonged and short communications between vehicles and the roadside, between vehicles, and between mobile equipment and fixed infrastructure points.
Wherever practicable, ISO 25112:2010 has been developed by reference to suitable extant standards, adopted by selection. Required regional variations are provided.
Application specific upper layers will not be included in ISO 25112:2010, but will be driven by application standards (which might not be technology specific).
