4.3.7.1 Applicability
The Subject to control by an indoor infrastructure and operation within an identifiable network requirement applies to
equipment sub-category 2.1, see clause 4.2.2, if the equipment operates with a mean e.i.r.p. spectral density higher
than -41,3 dBm/MHz or with a peak e.i.r.p. spectral density higher than 0 dBm/50 MHz.
4.3.7.2 Description
Subject to control by an indoor infrastructure and operation within an identifiable network, are closely related
requirements and therefore in the context of the present document a combined test is performed. The operation within
an identifiable network is confirmed inherently, if the subject to control by an indoor infrastructure can be demonstrated
successfully.
ETSI
13 Draft ETSI EN 302 065-2-5 V1.1.0 (2025-11)
Portable devices could be in general, due to their nature, operate indoor and outdoor. In order to ensure, that a portable
device is subject to control by an indoor infrastructure, the portable device shall pass tests to verify that fact, if its
intended use is to operate under the enhanced indoor devices regulation according to (EU) 2024/1467 [i.2].
4.3.7.3 Limits
The equipment shall fulfil the mean e.i.r.p. spectral density of -31,3 dBm/MHz and the peak e.i.r.p. density limit of
10 dBm/50 MHz under control by an indoor infrastructure and operation within an identifiable network.
Then, with a 10 seconds delay after the loosing of the control by an indoor infrastructure and/or operation within an
identifiable network, the equipment shall fulfil the mean e.i.r.p. spectral density limit of -41,3 dBm/MHz and the peak
e.i.r.p. spectral density limit of 0 dBm/50 MHz.
4.3.7.4 Conformance
The conformance test for being subject to control by indoor infrastructure and operate within an identifiable network is
defined in clause 5.3.7.
4.3.8 TX behaviour under the complete environmental profile
4.3.8.1 Applicability
The TX behaviour under the complete environmental profile requirement applies to the equipment sub-categories 1.1,
1.2 and 2.1, see clause 4.2.2.
4.3.8.2 Description
The TX behaviour under the complete environmental profile verifies the conformance of the mean e.i.r.p. spectral
density over the environmental profile as specified in clause 5.1.3.
For more information on the TX behaviour under the complete environmental profile, see ETSI TS 103 941 [3],
clause 4.3.1.
4.3.8.3 Limits
The TX behaviour is obtained by measuring the mean e.i.r.p. spectral density and OFR across the complete
environmental profile (see clause 5.1.3) and assessing the variation with respect to an adjusted Regulated Limit (RL).
The procedure to adjust the regulated limit is descripted in ETSI TS 103 941 [3], clause 6.4.
4.3.8.4 Conformance
The conformance test for TX behaviour under the complete environment profile is defined in clause 5.3.8.
The conformance test shall be done under the complete environmental profile as defined in clause 5.1.3.
4.4 Receiver requirements
4.4.1 General
The receiver requirements apply for the equipment sub-categories 1.2 and 2.1. See clause 4.2.2.
• Receiver Baseline Sensitivity (RBS), see clause 4.4.3.
• Receiver Baseline Resilience (RBR), see clause 4.4.4.
NOTE 1: The receiver requirements for EUT's covered by the scope of the present document are justified in ETSI
EN 303 883-2 [2], Annex C.
ETSI
14 Draft ETSI EN 302 065-2-5 V1.1.0 (2025-11)
NOTE 2: Equipment of sub-category 1.1 (see clause 4.2.2) is not required to fulfil any receiver requirements, because
they are UWB transmit only devices, which do not operate in UWB receive mode.
The conformance tests shall be done under normal conditions as defined in clause 5.1.2.
4.4.2 Wanted technical performance criteria
4.4.2.1 Message success ratio
Message Success Ratio (MSR) is used as a performance criterion for the RBS and RBR tests.
The equipment shall fulfil a message success ratio better than 90 %.
For the RBR test, the equipment shall meet this requirement also when the interferer is present.
4.4.2.2 Automatic recovery
Automatic recovery is used as a performance criterion for the RBR tests only.
The requirements for automatic recovery are listed below:
• The interference shall be present for at least 10 seconds.
• Automatic recovery of performance shall be completed 1 second after interference has been removed.
• 1 second after interference has been removed, the MSR measurement is started and the equipment shall fulfil a
message success ratio better than 90 %.
4.4.3 Receiver Baseline Sensitivity (RBS)
4.4.3.1 Applicability
The Receiver Baseline Sensitivity (RBS) requirement applies to equipment sub-categories 1.2 and 2.1, see clause 4.2.2.
4.4.3.2 Description
For the description of the RBS requirement see ETSI EN 303 883-2 [2], clause 5.4.1.
4.4.3.3 Limits
The Receiver Baseline Sensitivity (RBS) shall fulfil the following requirement:
Receiver Baseline Sensitivity: P ≤ -111,3 dBm/MHz
@EUT
NOTE 1: Received power at the equipment (P ) includes the RX antenna gain (of the integrated or associated or
@EUT
dedicated equipment antenna).
NOTE 2: Reasoning behind Receiver Baseline Sensitivity requirement:
Reliable operation can be achieved with a good link budget and/or installation of additional UWB nodes.
Spectrum efficiency can deteriorate, if link budget due to poor RX sensitivity is traded-off against node
count, as this will add unnecessary air traffic. This justifies the requirement for a "Receiver Baseline
Sensitivity" requirement.
NOTE 3: Receiver Baseline Sensitivity is defined with the same unit as mean e.i.r.p. spectral density, and therefore
the measurement methods for mean e.i.r.p. spectral density can be reused for quantifying the received
power at the equipment.
NOTE 4: The limit is derived from a path loss of 80 dB with a mean e.i.r.p. spectral density limit
of -31,3 dBm/MHz and a path loss of 70 dB with a mean e.i.r.p. spectral density limit of -41,3 dBm/MHz.
The RBS limit shall be met while fulfilling the message success ratio limit as defined in clause 5.4.2.

4.4.4.3 Limits
The present document considers two interference scenarios:
• Weak interference:
- Power levels as defined in Table 6 and Table 7.
- Message success ratio (clause 4.4.2.1) shall be fulfilled.
• Strong interference;
- Power levels as defined in Table 6 and Table 7.
- Automatic recovery (clause 4.4.2.2) shall
