Executive summary
The present document provides a limited set of baseline receiver requirements to address the spectrum efficiency
requirements of the RED and provides a sound basis to justify the use of this set in Harmonised Standards to claim
presumption of conformity. It addresses the Assessment of Compliance of Documents drafted by the ESOs clause 7 of
[i.7].
These baseline receiver requirements were developed based on the findings of ETSI TR 103 566 [i.2], where the signal
interferer handling concept from ETSI TS 103 361 [i.3] has been analysed on its applicability for the RED.
An example of a set of two parameters is given in clause 5 of the present document providing guidance for HS
development, which can be further refined by the responsible TB.
Baseline comprises the following parameters:
• receiver baseline sensitivity; and
• receiver baseline resilience.
These baseline parameters are put in relation to existing receiver parameters given in ETSI EG 203 336 [i.1].

6 ETSI TS 103 567 V1.1.1 (2019-09)
The present document specifies this baseline parameter concept and the corresponding test and measurement
procedures, but it does not specify receiver parameter values. These values should be derived from technical
specifications defined by the responsible ETSI Technical Committees (see clause 2.8.2 in [i.8]) and/or the findings of
regulatory studies conducted by the relevant bodies like CEPT ECC WG SE or other sources of state of the art
requirements.
An example mapping of the baseline parameters to radiodetermination (Annex C) and CEN DSRC Tolling systems
(Annex B) is proposed.
RX measurements have to be done in a normal operational environment covering the typical interference scenarios.
This operational environment can be derived from the intended use of the device to be tested. The relevant interfering
signals can be chosen based on the methodology specified in ETSI TS 103 361 [i.3] where a similar approach has been
taken for UWB based devices.
Introduction
Directive 2014/53/EU on the harmonisation of the laws of the Member States relating to the making available on the
market of radio equipment (the RED [i.4]) was ratified by the European Parliament at Strasbourg on 16 April 2014. The
previous legislation (the R&TTE Directive [i.13]) was repealed with effect from 13 June 2016. The RED came into
force on 13 June 2016 with a one-year transition period, during which both the old and new Directives could be used for
declaring product compliance. The European Commission requested ETSI to provide harmonised standards in support
of the RED in response to Standardisation Request M/536.
The scope of the RED is broader than that of the R&TTE Directive [i.13]. In addition, its Essential Requirements were
clarified, especially with respect to receivers. Receiver (RX) parameters were to be included in the standards to support
a more efficient use of the spectrum. In Annex F, a current list from DG GROW [i.5] is available mapping receiver
parameters from ETSI Guide [i.1] to relevant standards. This list is part of the assessment of compliance of harmonised
standards, see clause 7 in Vademecum Part I [i.7]. ETSI was required to create new or update its existing harmonised
standards accordingly. This task has presented new technical challenges in relation to certain equipment categories,
specifically for:
• receive-only equipment;
• radio determination equipment;
• radio equipment operating at frequencies below 9 kHz;
• radio equipment/systems in which the receiver should be tested within the system (e.g. inductive systems).
Some of these challenges have already been addressed by ETSI STF 494 (06/2015 - 03/2016) which developed a new
concept for RX requirements and tests for UWB devices, which is documented in ETSI TS 103 361 [i.3].
The subject of efficient use of radio spectrum is broad in scope but the theoretical basis for making statements about
spectrum efficiency is lacking. Factors that affect spectrum efficiency include transmit power, modulation rates,
receiver sensitivity and robustness to interference as well as medium access mechanisms and data transfer protocols.
The present document addresses receiver aspects only. For this purpose, it provides a limited set of applicable baseline
receiver requirements that address the spectrum efficiency requirement of the RED. Depending on the choice of
parameters, these baseline RX requirements encompass the classical parameters given in [i.1], see also Table 1.

1 Scope
The present document specifies a limited set of baseline receiver requirements aiming to meet the essential
requirements of Article 3.2 of the Radio Equipment Directive [i.4] by developing provisions for harmonised standards,
see clauses 2.8.2 and 2.10.2 in Vademecum Part III [i.8] to support assessment of compliance of harmonised standards,
see clause 7 in Vademecum Part I [i.7].
These receiver requirements are related to effective and efficient use of the radio spectrum and not to quality aspects of
products.
These baseline receiver parameters are equivalent to the receiver parameter as given in ETSI EG 203 336 [i.1].

4 Existing RX requirements and Spectrum Efficiency
4.1 Introduction
Article 3.2 of the RED [i.4] calls of "effective and efficient use of radio spectrum" without providing guidance on the
means or methods nor on the criteria to judge such use. Ideally, these criteria should be extractable from the relevant
regulatory documents including ECC reports, decisions and recommendations.
In order to assist its Technical Body members with the development of Harmonised Standards, ETSI adopted ETSI
EG 203 336 [i.1]. ETSI EG 203 336 [i.1] lists a variety of equipment parameters including many receiver parameters
that the TBs should consider in their work. This list is inclusive and does not provide guidance on the applicability of
the parameters to different technologies or types of equipment. Specific guidance on the relationship between these
parameters and their impact on efficient use of radio spectrum is not given.
Several of the RX parameters g
