Abstract
This document specifies communication requirements in support of the Smart Digital Tachograph (SDT) as identified by Regulation 2016/799 of the European Union[23].
The specification covers:
— the physical layer at 5,8 GHz for SDT communications (SDTC);
— the data link layer (DLL) of SDTC;
— the application layer of SDTC;
— SDTC profiles which provide coherent sets of communication tools for applications based on SDTC.
This document provides further information beneficial for the design and development of SDTC equipment.
