COMMISSION IMPLEMENTING DECISION (EU) 2019/785

of 14 May 2019

on the harmonisation of radio spectrum for equipment using ultra-wideband technology in the Union and repealing Decision 2007/131/EC

(notified under document C(2019) 3461)

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Decision No 676/2002/EC of the European Parliament and of the Council of 7 March 2002 on a regulatory framework for radio spectrum policy in the European Community (Radio Spectrum Decision) (1), and in particular Article 4(3) thereof,

Whereas:

| (1) | Commission Decision 2007/131/EC (2) harmonises the technical conditions for spectrum use by radio equipment based on ultra-wideband (‘UWB’) technology in the Union. It ensures that radio spectrum is available across the Union under harmonised conditions, eliminates barriers to the take-up of UWB technology and aims at creating an effective single market for UWB systems with significant economies of scale and benefits to the consumer. |
| --- | --- |

(1)

Commission Decision 2007/131/EC (2) harmonises the technical conditions for spectrum use by radio equipment based on ultra-wideband (‘UWB’) technology in the Union. It ensures that radio spectrum is available across the Union under harmonised conditions, eliminates barriers to the take-up of UWB technology and aims at creating an effective single market for UWB systems with significant economies of scale and benefits to the consumer.

| (2) | Although ultra-wideband signals are typically of extremely low power, the possibility of harmful interference with existing radiocommunication services exists and needs to be managed. Therefore, this Decision on the harmonisation of radio spectrum for UWB equipment should avoid harmful interference (including where this might arise from access to the radio spectrum by radio astronomy, earth exploration satellite and space research systems) and balance the incumbent services' interests against the overall policy objective of providing favourable conditions for the introduction of innovative technologies for the benefit of society. |

| (3) | On 16 March 2017, the Commission issued a permanent mandate, pursuant to Decision No 676/2002/EC, to the European Conference of Postal and Telecommunications Administrations (‘CEPT’) to identify the technical conditions for the harmonised introduction of radio applications based on UWB technology in the Union in order to provide updated technical conditions for such applications. |

On 16 March 2017, the Commission issued a permanent mandate, pursuant to Decision No 676/2002/EC, to the European Conference of Postal and Telecommunications Administrations (‘CEPT’) to identify the technical conditions for the harmonised introduction of radio applications based on UWB technology in the Union in order to provide updated technical conditions for such applications.

| (4) | In response to that permanent mandate, CEPT adopted a report (3) where it proposed four measures. Firstly, the technical conditions should describe material sensing devices in a more neutral way in order to allow for innovative solutions. Secondly, it should be possible to use the conditions for generic UWB usage also for material sensing applications. Thirdly, there should be a – 65 dBm/MHz limit for all material sensing devices including building material analysis (BMA) in the 8,5-10,6 GHz band. Fourthly, the possibility of a trigger-before-transmit mitigation for vehicular access control systems based on UWB technology should be introduced in the 3,8-4,2 GHz and 6-8,5 GHz frequency bands. |

(5)

This Decision should support the overall harmonisation of the UWB regulatory framework in order to improve consistency of limits and mitigation techniques between the different UWB regulations and allow for innovative solutions in the field of UWB technology.

| (6) | This Decision provides for regulatory limits and identifies mitigation techniques to ensure an efficient usage of spectrum while ensuring coexistence with other spectrum users. Technological evolution may provide other solutions that ensure at least an equivalent level of spectrum protection. For this reason, the use of alternative mitigation techniques, such as solutions found in future possible harmonised standards produced by the European Standardisation Organisations, should be allowed provided they ensure at least an equivalent level of performance and spectrum protection and verifiably respect the established technical requirements of this regulatory framework. |

‘Trigger-before-transmit’ mitigation is defined as a UWB transmission that is only initiated when necessary, specifically where the system indicates that UWB devices are nearby. The communication is either triggered by a user or by the vehicle. The subsequent communication can be considered as ‘triggered communication’. The existing LDC mitigation applies (or alternatively TPC in the 6 GHz to 8,5 GHz range). An exterior limit requirement must not be applied when using the trigger-before-transmit mitigation technique for vehicular access systems.

Trigger-before-transmit mitigation techniques that provide an appropriate level of performance in order to comply with the essential requirements of Directive 2014/53/EU shall be used for vehicular access systems. 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. These techniques shall respect the technical requirements of this Decision.

| --- | --- |

—

Contact based UWB material sensing devices, for which the UWB transmitter is only switched on when in direct contact with the material under investigation;

| --- | --- |

—

Non-contact based UWB material sensing devices, for which the UWB transmitter is only switched on when it is near the investigated material and the UWB transmitter is directed towards the material under investigation (for example manually by using a proximity sensor or by mechanical design).

Material sensing devices based on UWB technology shall comply either with the generic UWB regulation based on technical conditions specified in section 1 of this Annex or with the specific limits for material sensing devices as defined in sections 5.2 and 5.3.

The generic UWB regulation excludes fixed outdoor installations. Emissions radiated by a material sensing device must not exceed the limits of the regulation for generic UWB usage specified in section 1. Material sensing devices must fulfil the requirements of mitigation techniques specified for the generic use of UWB in section 1.

The specific limits for material sensing devices including the mitigation techniques are listed in the following tables. Emissions radiating from material sensing devices permitted under this Decision must be kept to a minimum and in any case not exceed the emission limits within the following tables. Compliance with the specific limits must be ensured by the device placed on a representative structure of the investigated material. The specific limits listed in the following tables are applicable in all environments for material sensing devices, except those to which note 5 of these tables, which excludes fixed outdoor installation in certain applicable frequency ranges, applies.
