ISO 25113:2010

ISO 25113:2010 selects the options appropriate for CALM using mobile wireless broadband (MWB) techniques conforming to ATIS 0700004-2005 (HC-SDMA) air interface and protocol specification recommended by ITU-R M.1801 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 25113:2010 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 25113:2010, but will be driven by application standards (which might not be technology specific).
