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

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.

Perception de télépéage - Mesure des interférences sur des dispositifs de péage et de tachygraphe provenant de dispositifs de réseaux locaux sans fil fonctionnant dans la gamme de fréquences de 5,8 GHz - Structure de la suite d’essais et objectifs des essais

Le présent document spécifie la mise en place d'un système d'essai ainsi que la structure de la suite d'essais et les objectifs des essais, c'est-à-dire les essais visant à évaluer le niveau d'interférence émis par les dispositifs RLAN fonctionnant dans la gamme des 5,8 GHz sur les OBE de péage et les équipements tachygraphes fonctionnant dans la même gamme de fréquences.
Afin d'obtenir des résultats génériques qui pourront ensuite être utilisés pour la conception de techniques d'atténuation adéquates, l'environnement d'essai et les cas d'essai visent à :
1.   acquérir un grand nombre de transactions sur des OBE de marques et de caractéristiques différentes ;
2.   assurer l'anonymat des résultats.
Les résultats d'essai permettent de calculer les moyennes ainsi que les écarts-types.
Les essais spécifiés dans le présent document ont pour seul but d'étudier les interférences émises par un RLAN sur les communications DSRC. Les autres facteurs susceptibles d'influencer les performances de la DSRC et le niveau d'interférence dans un scénario d'essai donné ne sont pas soumis aux spécifications d'essai et ne relèvent donc pas du domaine d'application du présent document.

Introduction
It is well known that the dedicated short-range communication (DSRC) band of frequencies around
5,8 GHz used in Europe and Japan for tolling is increasingly subject to interferences by other radio
frequency (RF) technologies. In the past, extensive analysis, theoretical studies, and tests of real systems
have been conducted that led to the specification of measures to prevent detrimental interferences
between tolling devices and ITS devices operating in the 5,9 GHz band (ETSI ITS-G5) and ensure their co-
existence. The recent development in radio LAN (RLAN) technologies have brought portable RLAN
devices operating in the 5,8 GHz band, so that harmful interferences with tolling devices are to be
expected. It is to be noted that other important European services operating in the same band other than
tolling are impacted, such as the regulated European smart tachograph, which exchanges data with
roadside units using CEN DSRC technology and a protocol similar to that used for tolling.
Mitigation techniques to reduce or eliminate harmful interferences can be determined based on analytical
models. However, the characteristics of radio transmissions at this range of frequencies are such that it
is impossible to consider all factors that impact interference phenomena. Theoretical assumptions need
to be verified by field tests.
It is essential that such tests, which may lead to regulated mitigation techniques, are standardized
together with the physical setup in which the tests are performed.
The present document specifies a standardized test setup and a test suite structure and test purposes
(TSS and TP) to measure interferences on incumbent road tolling and tachograph devices from RLANs
operating in the 5,8 GHz range.
The tests are designed to be run in a controlled environment (anechoic chamber) in order to minimize
other factors that may have an impact on measurements with the DSRC communication. Among these
factors, but not limited to the following list, are:
• weather condition: influence of moisture, rain and snow;
• (wrong) mounting of a device (inside a vehicle): on the side window, built into the dashboard, behind
or under the se
