This document specifies communication requirements in support of the "Smart Digital Tachograph" (SDT) as identified by Regulation of the European Union.
The specifications cover:
• 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.
