European Digital Tachograph - Interference from WiFi on the DSRC remote control link

In 1999, ESF developed and tested the first wireless remote control radio link to interrogate the planned European Digital Tachograph. This work was done in a research activity funded by the German Government. The test radio link was designed for the 2,4 GHz ISM band.

In the meanwhile, the CEN DSRC semi-passive tranponder technology operated at 5,8 GHz was selected for this purpose. New attempts in the Wi-Fi world demanding more frequency bands leads to the risk, that Wi-Fi operated close to 5,8 GHz might hamper the legally required interrogation link for the Digital Tachograph. Thus, CEN/TC 278 wrote a test standard, and interference tests are scheduled for July / August 2024, to be performed in an anechoic chamber at the Joint Research Centre of the European Commission in Ispra.

Support in technical developments and management of standards development

From April 2024 on I can sign new development contracts. I offer my technical expertise to develop ASN.1 modules and TTCN-3 test suites, and my management expertise to be project leader in the domain of standards develpoment at e.g. ISO, CEN and ETSI.

The king is dead, long live the king!

That could be applied to ITS. For about two decades, starting with the EC's CVIS project, we worked on "Cooperative ITS" (C-ITS), which is now being substituted or expanded by "Connected, Cooperative and Automated Mobility" (CCAM); see also the web of the European Commission. The below graphic is taken from the EC's CCAM web and gives a hint on the continuation of C-ITS in CCAM.

C-ITS wheel - CCAM

Already C-ITS contributed to automated mobility, although "automatic driving" was not at all visible in the foreground. Thus, many standards carrying the C-ITS flag still can and will be used for CCAM.

In ISO/TC 204, I am currently leading projects to review and revise essential standards of which I was the initial project leader:

These three standards provide general features and are independent from a specific communications technology.

EN ISO 17419 manages globally unique identifiers and is linked to the ISO/TC 204 online registry. One of the popular identifiers is the ITS-AID that uniquely identifies an application.

EN ISO 17423 is a proposal on how to automatically manage a set of available communication protocol stacks in a station such the correct one or the best suited one is selected for a given application.

EN ISO 18750 gives support in implementing dynamic data in maps.

A new activity in preparation is the revision of

This standard specifies three facility layer communication services supporting applications to manage messages in the receive and transmit direction. The goal is to split the document to get one part for each facility layer communication service, and to add a fourth part for the specification of technical details related to ITS message sets. ITS message sets are introduced already in the ITS station and communication architecture ISO 21217 / ETSI EN 302 665 (I was editor of both version of basically the same architecture - this shows an unfortunate ongoing competition between these standard development organizations.).

Liaison between ISO/TC 204/WG 14 and ETSI TC ITS

I was nominated to be liaison officer between ISO/TC 204/WG 14 on "vehicle/roadway warning and control systems" and ETSI TC ITS WG1 and WG 5
