This document is currently submitted to the Vote on TR.
Introduction
This document contains results of the test campaign on CEN dedicated short-range communication
(DSRC) technology that was conducted at the European Commission’s Joint Research Centre (JRC) in
Ispra (Italy) during two weeks in August 2024.
CEN DSRC technology has been developed specifically to provide a reliable and effective communication
means for traffic and transport applications in single lane and high speed multilane free flow
environments. The aim of the test was to evaluate the effects of the radio interference caused by radio
local area network (RLAN) devices operating in frequency bands close to or within the 5,8 GHz CEN
DSRC frequency band, whilst noting that the CEN DSRC technology is adopted in the following European
Union regulations:
[1]
• European electronic toll service (EETS) (i.e. Directive (EU) 2019/520 and
[2]
Regulation (EU) 2020/204 )
[3],
• Tachographs in road transport (i.e. Regulation (EU) No 165/2014, Regulation (EU) 2020/1054)
[4]
Regulation (EU) 2021/1228 , Implementing Regulation 2016/799 and its Appendix 14 “Remote
[16]
communication function (DSRC)”
• Maximum authorised weights and dimensions for road motor vehicles (i.e. Directive (EU)
[17])
2015/719
Tests were performed based on the specifications in CEN/TS 18078.
Six victim devices, i.e. roadside equipment (RSE) and on-board equipment (OBE), used in the test
campaign have been provided, configured and operated by 5 manufacturers. The provided devices are
compliant to European standards for CEN DSRC electronic fee collection (EFC), aka as electronic road
tolling, i.e. EN 12253, EN 15509, ETSI EN 300 674-2-1 and ETSI EN 300 674-2-2. Results for high data
rate DSRC devices compliant to ETSI ES 200 674-1 are not included in this report.
Interrogators for a remote readout of the tachograph OBE and the weights and dimensions OBE use the
[6]
same DSRC technology . These OBE devices are mounted like an EFC OBE in trucks. The RSE mounting
geometry for this application is similar to the RSE test setup used in the test campaign as shown in
Figure 7. Therefore, the findings in this document relating to CEN DSRC EFC devices, especially those for
trucks when interrogated by a fixed compliance checking RSE, also apply to EU-regulated tachograph
devices.

5 Main findings and conclusions
This document summarizes the results from measurements undertaken to evaluate the interference of
RLAN signals to CEN DSRC devices. The measurement setup takes RLAN devices into account that
operate in different parts of the 5 GHz band (see Figure 1). In this document, RLAN equipment means
equipment that usually operates under the RLAN regulation (e.g. devices following the Wi-Fi®
specification). It is noteworthy that those devices can also operate above 5 725 MHz in accordance with
[12] [18]
the CEPT SRD recommendation and SRD regulation , when applying its requirements on
techniques to access spectrum and mitigate interference . The RLAN channels chosen for the
measurements in this document are in two different regulatory domains with different usage conditions,
which are not discussed in detail here. For simplicity, the interference signals and radio channels are
denoted RLAN signals and RLAN channels in this document independent from the regulatory regime in
Europe.

Figure 1 — RLAN channels used for CEN DSRC interference testing
In general, CEN DSRC performs reliably, even when exposed to some degree of interference or blocking.
However, the measurement results in subclause 8.2 show that the use of RLAN equipment within the
CEN DSRC frequency band can cause harmful interference to the CEN DSRC RSE, even at low power
levels. This makes the use of typical RLAN equipment such as Wi-Fi® devices within the CEN DSRC
frequency band in vehicles problematic , even when operating under the SRD regulation. Where RLAN
signals with a low power level coming from some distance are much less of a problem, since the
directivity of the RSE antennas is high and the RSE antennas are tilted down towards the road surface.
Out of band (OOB) emissions coming from RLAN devices operated in adjacent frequency bands, can be
a problem when the devices are in a vehicle, since they cause in-band interference to the RSE, which
[13]
might in some cases be harmful . Whilst OOB emissions from RLAN transmitters located further away
from the RSE are not critical due to the RSE antenna directivity as shown in subclause 8.2.2.
Techniques to access spectrum and mitigate interference that provide an appropriate level of performance to
[19]
comply with the essential requirements of Directive 2014/53/EU shall be used. If relevant techniques are
described in harmonised standards or parts thereof the references of which have been published in the Official
Journal of the European Union under Directive 2014/53/EU, performance at least equivalent to these techniques
shall be ensured. ETSI EN 300 440 is the harmonised standard for access to radio spectrum relevant for SRD.
European frequency regulation does not foresee RLAN applications in the frequency band from 5725 MHz to
5925 MHz. Nevertheless, Wi-Fi devices based on the RLAN specification are allowed to be used in Europe under
the SRD regulation with reduced transmit power level within the CEN DSRC frequency band from 5795 MHz to
5815 MHz.
This finding obtained for interference to the RSE is consistent with studies conducted by frequency
[13],[14]
regulators in the CEPT, in which the RSE has been the primary focus of investigations . The RSE
antenna directivity has been considered in such studies by considering a side lobe attenuation. The side
lobe attenuation of 15 dB used in the CEPT studies is consistent with the measurements reported in this
document. The side lobe attenuation reduces the necessary separation distance, although it remains
quite significant along the main lobe direction, to protect CEN DSRC from interference.
The measurement results in subclause 8.1 show that a CEN DSRC OBE is much less susceptible to
interference from RLAN signals within the CEN DSRC frequency band compared to a CEN DSRC RSE. For
the worst case where the interference signal is directed into the antenna main lobe of the interfered
device, this difference is in the order of 30 dB.
For the OBE, specific situations were found where interference caused by RLAN located at frequencies
outside the CEN DSRC frequency band might cause blocking in the OBE receiver, which reduces the
performance of the DSRC communication. Subclause 8.1.5 shows that this problem mainly arises when
the interferer is in front of the vehicle and in the main lobe of the OBE antenna, since the OBE antenna
points in the driving direction. There was only one blocking result measured from the back of an OBE.
This result shows 10 dB less interference susceptibility than from the front. Hence, a strong interferer
within the vehicle close to this measured OBE might cause blocking when it is directed straight to the
back of the OBE. For the more common cases where the interference signal is coming from the side of
the OBE, the interference signal can be 25 dB to 30 dB stronger than an interference signal coming from
the front to cause blocking, as confirmed by several measurements.
To address the risk of blocking to OBE and to further enhance the robustness of CEN DSRC in the future,
further standardization work (within CEN and ETSI) can be beneficial.
6 Test setup
6.1 General
The main aim of the interference test was to determine the level of harmful interference caused by RLAN
devices to transactions of CEN DSRC systems as a victim. In the experiments, a typical setup and
parameterisation was used to abstract from various situations found in practice. In the real usage
scenarios, the exchanged data between an RSE and an OBE (sequences of requests and responses)
differs for various EFC and interrogation applications. In addition, the down link from the RSE and the
responses of the OBE in the uplink are different in terms of data content, data rate, and frame duration.
To make the results comparable and independent of the CEN DSRC application, simple echo commands
were used as test transaction. Where the data sent by the RSE is sent back by the OBE, to focus on
measuring the frame error ratio (FER) and to simplify testing.
Different victim devices and measurement setups were used. They differ in the following points:
• the manufacturer and type of device under test (DUT);
• the OBE device type and mounting (either truck or passenger car use);
• the CEN DSRC power level (receive power level) at the OBE;
• the direction of the interference signal relative to the DUT;
• the bandwidth of the interference signal;
• the centre frequency of the interference signal.
The OBE has been positioned on a small screen made of laminated glass, a material which is also used
for not metallized windscreens of passenger vehicles. The size of the screen was 30 cm times 30 cm what
exceeds the dimensions of a typical OBE by at least 8 cm (along its “longest side”), which is more than a
wavelength of the used CEN DSRC and RLAN signals. This allows simple mounting of the OBE, while
maintaining similar radio propagation properties as in real passenger vehicle installations.
As far as the interferer is concerned, the RLAN emulator was set to transmit random sequences of data
packets to completely occupy the respective radio channel in time and frequency (worst case). A full
channel occupation was chosen to measure the packet error ratio as function of the incident interferer
power level independent of the interferer duty cycle.
A quadrature amplitude modulation (QAM) was used for the RLAN interferer, since it caused the
strongest interference to the OBE.
6.2 Test environment setup
The test environment (the shielded chamber laboratory VELA-9) has been offered and configured by
the Sustainable, Smart and Safe Mobility Unit (JRC.C.4) of the European Commission’s JRC, in Ispra
(Italy).
The setup of the vector signal generator for the interfering signal has been prepared and operated by
JRC personnel.
RLAN waveforms were calculated by use of MATLAB ® (Release 2023b) and the WLAN Toolbox
(Release 2023b) by JRC personnel. A complete description of the interfering device can be found in the
[5]
JRC Test report .
6.3 Mechanical test setup
Interference tests are specified in CEN/TS 18078.
The victim devices were either mounted on a pole (to emulate the installation of an RSE) or on a tripod
behind a windscreen (OBE), resembling typical installations of EFC and interrogation stations.
Figure 2 shows the elevation view of the test setup with the elevation angles and an OBE as DUT.
For all setups, the RSE was mounted in such a way that the main lobe of its antenna pointed towards the
phase centre of the OBE antenna. Since the OBE receive (RX) power level at this point was determined,
only the elevation difference between the RSE and OBE antenna main lobes is relevant for the
interference evaluation.
The RLAN antenna pointed towards the phase centre of the DUT antenna with an elevation of 0°, i.e. it
was at the DUT level. It was moved around the DUT in the horizontal plane where an interferer azimuth
of 0° relates to interference coming from the direction of the DUT antenna main lobe azimuth.
For the RSE measurement a simplified setup as shown in Figure 3 and Figure 7 was used, where the RSE,
the OBE, and the RLAN antenna were mounted on the same level.
The Monitor antenna (④ in Figure 4) was used to monitor the proper function of the RLAN and the CEN
DSRC signal.

Figure 4 outlines the top view of the test setup.
The antenna main lobe of the RSE or OBE ① and the DUT ② were aligned to each other. If the DUT ②
was an OBE as shown in Figure 2, Figure 5, and Figure 6 then an RSE was mounted at position ①,
otherwise if the DUT was an RSE then an OBE was mounted at position ① as can be seen in Figure 7.
The RLAN interfering device antenna ③ was positioned at 1 m distance to the DUT at different
interferer incident azimuth angles in relation to the CEN DSRC line-of-sight path direction to perform
different test sequences.
The Monitor antenna ④ was used to monitor the proper function of the RLAN and the CEN DSRC signal.
NOTE For Figure 2, Figure 3 and Figure 4 it is assumed that the antenna main lobe is directed perpendicular
to the front of the device.
Figure 4 —Schematic top view of the test setup
Figure 5 and Figure 6 show a setup with the interferer ③ to an OBE as DUT ② being positioned outside
a vehicle at a 30° RLAN azimuth angle in relation to the CEN DSRC line-of-sight. The RSE ① has been
positioned at about 3 metres height to emulate a private vehicle at a fixed RSE.
Other measurements featured OBE and RSE positioned at the same level to simulate the readout of the
OBE by a mobile reader positioned at the roadside or on a vehicle, used for the interrogation of a
tachograph for a CEN DSRC compliance checking communication with commercial vehicles (trucks) as
shown in Figure 7.
Note that the monitor antenna ④ in the centre of Figure 5 was only used to monitor the correct
configuration of the test equipment. It was connected to a spectrum analyser operated by JRC personnel.
This antenna was also used in the preparation and calibration of the test setup to determine the CEN
DSRC down link power level at the position of the OBE and the interferer power level at the DUT.

Figure 8 shows the cabling of the test setup for an OBE as DUT. The cabling for an RSE as DUT was the
same, only the orientation of the interferer antenna ③ was changed to point towards the RSE.
