Introduction
Directive 2014/53/EU [i.11] on the harmonisation of the laws of the Member States relating to the making available on
the market of radio equipment, known as the RED - Radio Equipment Directive, was ratified by the European
Parliament at Strasbourg on 16 April 2014. The previous legislation, the R&TTE Directive [i.54], was repealed with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 [i.11] is broader than that of the R&TTE Directive [i.54]. 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 . Therefore, 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, especially 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).
ETSI

6 ETSI TR 103 566 V1.1.1 (2018-10)
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.1] (Receiver
technical requirements, parameters and measurement procedures to fulfil the requirements of the Directive
2014/53/EU [i.11]). This TS contains alternative receiver requirements and test procedures for typical use-cases and
applications of UWB technology. All standards of ERM TGUWB are referring to ETSI TS 103 361 [i.1] for receiver
requirements.
The main difference between this alternative concept and "classical" receiver requirements (such as receiver sensitivity)
lies in the definition of hybrid RX-parameters, which constitute a combination of one or more receiver parameters and
an intended usage scenario.
In certain applications, receiver parameters are closely linked with the intended usage scenario. That means, these
devices cannot be tested in isolation from these scenarios. The performance criteria of RF system deploying these
receiver parameters are determined by the usage scenario. Examples are given in clause 8.
For others, conducted measurements required for some classical receiver parameters could not be performed due to the
high level of integration in some devices, e.g. if no antenna port connector is available. Similarly, required access points
to measure some classical receiver parameters might not be available.
Some devices operate in a shared spectrum environment without e.g. channel definitions leading to a high probability of
interference.
Several other ETSI ERM TGs are using a similar concept in the new versions of harmonised standards for the RED :
• ETSI EN 301 091-1 [i.2]
• ETSI EN 301 091-2 [i.3]
• ETSI EN 303 417 [i.4]
• ETSI EN 303 447 [i.5]
In January 2015, CEPT (ECC\ WGSE\ SE21) created a new work item (SE21_18) [i.46] "to evaluate relevant receiver
parameters, considering the future role of receiver parameters in spectrum management and sharing studies". This
ongoing work aims to provide some guidance on receiver requirements (planned is first an ECC Report and in a second
step an ECC Recommendation) and could have a significant impact on standardization in ETSI. The outcome of the
work of STF 494 (ETSI TS 103 361 [i.1]) was presented to SE21 and raised many questions.
The main questions from SE/SE21 were:
• How can the alternative concept ensure a minimum sensitivity of the radio system?
• Is it possible to implement the concept into the spectrum engineering process (e. g. use in SEAMCAT or for
the definition of interference scenarios)?
• Can the concept demonstrate/ensure that equipment supports an efficient use of the spectrum?
The discussion with SE21 is still ongoing and requires support from ETSI. Answering the questions from SE21 will be
one of objectives of this STF.

1 Scope
The present document presents a generic description of the hybrid RX-requirements concept for implementation into
harmonised standards. The new concept is intended to complement the framework for classical receiver parameters by
providing alternative RX parameters that could be used in use cases of radio devices where the classical receiver
parameters framework described in ETSI EG 203 336 [i.6], clause on RX where alternatives are allowed) cannot be
applied, e.g. if:
• there is no possibility to apply classical receiver parameters and parameters needed for compatibility or
sharing studies (e.g. RFID tags and some SRDs);
• classical receiver parameters do not fulfil the requirements for describing the performance of the receiver (e.g.
UWB, radio-determination, and inductive systems).
The present document will evaluate the relationship of the new concept with the classical RX- parameter framework,
such as blocking, sensitivity and adjacent channel selectivity.
The present document presents exemplary use cases and extracts related RX parameter to describe a harmonised
extension of the existing RX parameter framework.
The STF will ensure that the conclusions of its work should be included in harmonised standards in the following ways:
• It will provide a way to define clear limits that are objective, measurable and repeatable.
• It should ensure that a receiver to which the defined limits are applied has a level of performance that allows it
to operate as intended and protects it against potential harmful interference.
• It will not define specific values for limits or device-related requirements but focus on the procedure and
definitions of appropriate receiver parameters.
The present document is the first deliverable of STF 541 and it will be followed by an ETSI Technical Specification.
The present document provides an overview of the situation regarding receiver requirements including the definitions,
required parameters (e.g. interfering signals definition). The later TS will provide conformance test procedures for the
different use-cases/scenarios. The TS is intended to be used as a normative reference in ETSI harmonised standards
which have "signal interferer handling" as an essential RX-requirement.
During the proposed action, a set of evaluation measurements will be performed applying the new concept, and the
feedback collected will be included in the final definition of the test and measurement procedures.
The output of the STF could be suitable for incorporation into a revision of the ETSI Guide (ETSI EG 203 336 [i.6]) to
Harmonised Standards under the RED.
