Electronic fee collection - Measurement of interferences on tolling and tachograph devices from radio local area network devices operating in the 5,8 GHz frequency range - Test suite structure and test purposes CEN/TS 18078:2024

Publication date:   Apr 18, 2024

Scope

This document specifies the set-up of a testing system and the test suite structure and test purposes, i.e. tests to be used to assess the level of interference from RLAN devices operating in the 5,8 GHz range on tolling and tachograph devices operating in the same frequency range.
To obtain generalized results that can subsequently be used to design appropriate mitigation techniques, the test environment and the test cases are designed to:
1. acquire a large number of transactions on devices of different makes and characteristics;
2. ensure anonymity of results.
The test results ensure calculation of averages as well as standard deviations.
The tests specified in this document are for the sole purpose of investigating RLAN interference over DSRC communications. Other factors that can impact the performance of DSRC and also the level of interference in a test scenario are not subject to test specifications and out of the scope of this document.
