Introduction

The present document provides measurement procedures for receiver requirements to address the spectrum efficiency

requirements of the RED [i.10].

The basis for this RX concept was developed by ETSI during two Special Task Forces.

First Special Task Force: ETSI STF 494; Update of the UWB related Harmonised Standards covering the essential

requirements of article 3.2 of the RED [i.10].
The STF 494:
• Started: 2015-05-25
• Ended: 2016-03-31
Outcome:
• ETSI TS 103 361 [i.4]

The second Special Task Force: ETSI STF 541; Signal interferer handling, a new RX requirement to cover the

essential requirements of article 3.2 of the RED [i.10], was a continuation to implement and consider comments

received after the publication of the ETSI TS 103 361 [i.4].
The STF 541:
• Started: 2017-10-06
• Ended: 2019-05-31
Outcome:
• ETSI TR 103 566 [i.2]
• ETSI TS 103 567 [i.3]

There is no specification of receiver parameter values within the present document. These values will be derived from

technical specification defined by the responsible ETSI Technical Committees and/or the findings of regulatory studies

conducted by the relevant bodies like CEPT ECC WG SE. The limits/values for the baseline RX-conformance

requirements will be specified in the related standard.

In addition to the two receiver baseline requirements it can be necessary that the RX spurious emission requirement

could be a further RX requirement in the related standard. This could be necessary if the EUT has a receive only mode

or if it is not collocated to the transmitter. The present document specifies the receiver spurious emission requirement

and the corresponding test and measurement procedure in clause 5.2.

The present document provides practical information and guidance for the compliance receiver tests of UWB and Short

Range technology and devices.

It is recommended that, in drafting the related standards, a thorough analysis is conducted on all possible applicable

receiver parameters (see annex C), selecting the most appropriate RX-requirements and having a robust reasoning for

those that are disregarded.

1 Scope

The present document provides measurement procedures for receiver requirements to address the spectrum efficiency

requirements of the RED [i.10].

The baseline receiver concept is a set of two parameters given in clause 5 of the present document providing guidance

for HS development, which can be further refined by the responsible TB.
Baseline receiver concept comprises the following parameters:
• Receiver Baseline Sensitivity (RBS); and
• Receiver Baseline Resilience (RBR).

The Baseline receiver concept is a further development of the signal interferer handling concept, see ETSI

TS 103 361 [i.4].

Introduction

The present document provides measurement procedures for receiver requirements to address the spectrum efficiency

requirements of the RED [i.10].

The basis for this RX concept was developed by ETSI during two Special Task Forces.

First Special Task Force: ETSI STF 494; Update of the UWB related Harmonised Standards covering the essential

requirements of article 3.2 of the RED [i.10].
The STF 494:
• Started: 2015-05-25
• Ended: 2016-03-31
Outcome:
• ETSI TS 103 361 [i.4]

The second Special Task Force: ETSI STF 541; Signal interferer handling, a new RX requirement to cover the

essential requirements of article 3.2 of the RED [i.10], was a continuation to implement and consider comments

received after the publication of the ETSI TS 103 361 [i.4].
The STF 541:
• Started: 2017-10-06
• Ended: 2019-05-31
Outcome:
• ETSI TR 103 566 [i.2]
• ETSI TS 103 567 [i.3]

There is no specification of receiver parameter values within the present document. These values will be derived from

technical specification defined by the responsible ETSI Technical Committees and/or the findings of regulatory studies

conducted by the relevant bodies like CEPT ECC WG SE. The limits/values for the baseline RX-conformance

requirements will be specified in the related standard.

In addition to the two receiver baseline requirements it can be necessary that the RX spurious emission requirement

could be a further RX requirement in the related standard. This could be necessary if the EUT has a receive only mode

or if it is not collocated to the transmitter. The present document specifies the receiver spurious emission requirement

and the corresponding test and measurement procedure in clause 5.2.

The present document provides practical information and guidance for the compliance receiver tests of UWB and Short

Range technology and devices.

It is recommended that, in drafting the related standards, a thorough analysis is conducted on all possible applicable

receiver parameters (see annex C), selecting the most appropriate RX-requirements and having a robust reasoning for

those that are disregarded.

1 Scope

The present document provides measurement procedures for receiver requirements to address the spectrum efficiency

requirements of the RED [i.10].

The baseline receiver concept is a set of two parameters given in clause 5 of the present document providing guidance

for HS development, which can be further refined by the responsible TB.
Baseline receiver concept comprises the following parameters:
• Receiver Baseline Sensitivity (RBS); and
• Receiver Baseline Resilience (RBR).

The Baseline receiver concept is a further development of the signal interferer handling concept, see ETSI

TS 103 361 [i.4].

7 Final draft ETSI EN 303 883-2 V1.2.1 (2020-12)
Introduction

The present document provides measurement procedures for receiver requirements to address the spectrum efficiency

requirements of the RED [i.10].

The basis for this RX concept was developed by ETSI during two Special Task Forces.

First Special Task Force: ETSI STF 494; Update of the UWB related Harmonised Standards covering the essential

requirements of article 3.2 of the RED [i.10].
The STF 494:
• Started: 2015-05-25
• Ended: 2016-03-31
Outcome:
• ETSI TS 103 361 [i.4]

The second Special Task Force: ETSI STF 541; Signal interferer handling, a new RX requirement to cover the

essential requirements of article 3.2 of the RED [i.10], was a continuation to implement and consider comments

received after the publication of the ETSI TS 103 361 [i.4].
The STF 541:
• Started: 2017-10-06
• Ended: 2019-05-31
Outcome:
• ETSI TR 103 566 [i.2]
• ETSI TS 103 567 [i.3]

There is no specification of receiver parameter values within the present document. These values will be derived from

technical specification defined by the responsible ETSI Technical Committees and/or the findings of regulatory studies

conducted by the relevant bodies like CEPT ECC WG SE. The limits/values for the baseline RX-conformance

requirements will be specified in the related standard.

In addition to the two receiver baseline requirements it can be necessary that the RX spurious emission requirement

could be a further RX requirement in the related standard. This could be necessary if the EUT has a receive only mode

or if it is not collocated to the transmitter. The present document specifies the receiver spurious emission requirement

and the corresponding test and measurement procedure in clause 5.2.

The present document provides practical information and guidance for the compliance receiver tests of UWB and Short

Range technology and devices.

It is recommended that, in drafting the related standards, a thorough analysis is conducted on all possible applicable

receiver parameters (see annex C), selecting the most appropriate RX-requirements and having a robust reasoning for

those that are disregarded.

1 Scope

The present document provides measurement procedures for receiver requirements to address the spectrum efficiency

requirements of the RED [i.10].

The baseline receiver concept is a set of two parameters given in clause 5 of the present document providing guidance

for HS development, which can be further refined by the responsible TB.
Baseline receiver concept comprises the following parameters:
• Receiver Baseline Sensitivity (RBS); and
• Receiver Baseline Resilience (RBR).

The Baseline receiver concept is a further development of the signal interferer handling concept, see ETSI

TS 103 361 [i.4].

First Special Task Force: ETSI STF 494; Update of the UWB related Harmonised Standards covering the essential

requirements of article 3.2 of the RED [i.10].
The STF 494:
• Started: 2015-05-25
• Ended: 2016-03-31
Outcome:
ETSI TS 103 361 [i.4]

The second Special Task Force: ETSI STF 541; Signal interferer handling, a new RX requirement to cover the

essential requirements of article 3.2 of the RED [i.10], was a continuation to implement and consider comments

received after the publication of the ETSI TS 103 361 [i.4].
The STF 541:
• Started: 2017-10-06
• Ended: 2019-05-31
Outcome:
• ETSI TR 103 566 [i.2]
• ETSI TS 103 567 [i.3]

There is no specification of receiver parameter values within the present document. These values will be derived from

technical specification defined by the responsible ETSI Technical Committees and/or the findings of regulatory studies

conducted by the relevant bodies like CEPT ECC WG SE. The limits/values for the baseline RX-conformance

requirements will be specified in the related standard.

In addition to the two receiver baseline requirements it can be necessary that the RX spurious emission requirement

could be a further RX requirement in the related standard. This could be necessary if the EUT has a receive only mode

or if it is not collocated to the transmitter. The present document specifies the receiver spurious emission requirement

and the corresponding test and measurement procedure in clause 5.2.

The present document provides practical information and guidance for the compliance receiver tests of UWB and Short

Range technology and devices.

It is recommended that, in drafting the related standards, a thorough analysis is conducted on all possible applicable

receiver parameters (see annex C), selecting the most appropriate RX-requirements and having a robust reasoning for

those that are disregarded.

1 Scope

The present document provides measurement procedures for receiver requirements to address the spectrum efficiency

requirements of the RED [i.10].

The baseline receiver concept is a set of two parameters given in clause 5 of the present document providing guidance

for HS development, which can be further refined by the responsible TB.
Baseline receiver concept comprises the following parameters:
• Receiver Baseline Sensitivity (RBS); and
• Receiver Baseline Resilience (RBR).

The Baseline receiver concept is a further development of the signal interferer handling concept, see ETSI

TS 103 361 [i.4].
