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.
