# 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), Division 5.3: Non-contact based material sensing devices Extent: E+W+S+N.I. The specific limits for maximum mean power spectral density (e.i.r.p.) and maximum peak power (e.i.r.p.) for non-contact based material sensing devices using UWB technology are defined in the table below. Devices using the Listen Before Talk (‘LBT’) mechanism are permitted to operate in the 1,215 GHz to 1,73 GHz frequency range with a maximum mean e.i.r.p. spectral density of – 70 dBm/MHz and in the 2,5 GHz to 2,69 GHz and 2,7 GHz to 3,4 GHz frequency ranges with a maximum mean e.i.r.p. spectral density of – 50 dBm/MHz and a maximum peak e.i.r.p. of – 10 dBm/50 MHz. The LBT mechanism is defined in clauses 4.5.2.1, 4.5.2.2 and 4.5.2.3 of ETSI Standard EN 302 065-4 V1.1.1. Alternative mitigation techniques may be used if they ensure at least an equivalent performance and level of spectrum protection in order to comply with the corresponding essential requirements of Directive 2014/53/EU and respect the technical requirements of this Decision. To protect the radio services, non-fixed installations must fulfil the following requirement for total radiated power: (a) In the 2,5 GHz to 2,69 GHz and 4,8 GHz to 5 GHz frequency ranges, the total power spectral density must be 10 dB below the maximum e.i.r.p. spectral density. (b) In the 3,4 GHz to 3,8 GHz frequency range, the total power spectral density must be 5 dB below the maximum e.i.r.p. spectral density. To protect the Radio Astronomy Service (RAS) in the 2,69 GHz to 2,7 GHz and 4,8 GHz to 5 GHz bands, the total power spectral density must be below – 65 dBm/MHz. Limitation of the Duty Cycle to 10 % per second. No fixed outdoor installation is permitted. Within the 3,1 GHz – 4,8 GHz band, devices implementing LDC mitigation technique are permitted to operate with a maximum mean e.i.r.p. spectral density of – 41,3 dBm/MHz and a maximum peak e.i.r.p. of 0 dBm defined in 50 MHz. The LDC mitigation technique and its limits are defined in clauses 4.5.3.1, 4.5.3.2 and 4.5.3.3 of ETSI Standard EN 302 065-1 V2.1.1. Alternative mitigation techniques may be used if they ensure at least an equivalent performance and level of spectrum protection in order to comply with the corresponding essential requirements of Directive 2014/53/EU and respect the technical requirements of this Decision. When LDC is implemented, note 5 applies. Within the 3,1 GHz – 4,8 GHz and 8,5 GHz - 9 GHz bands, devices implementing DAA mitigation technique are permitted to operate with a maximum mean e.i.r.p. spectral density of – 41,3 dBm/MHz and a maximum peak e.i.r.p. of 0 dBm defined in 50 MHz. The DAA mitigation technique and its limits are defined in clauses 4.5.1.1, 4.5.1.2 and 4.5.1.3 of ETSI Standard EN 302 065-1 V2.1.1. Alternative mitigation techniques may be used if they ensure at least an equivalent performance and level of spectrum protection in order to comply with the corresponding essential requirements of Directive 2014/53/EU and respect the technical requirements of this Decision. When DAA is implemented, note 5 applies. Technical requirements for non-contact based UWB material sensing devices Frequency range Maximum mean power spectral density (e.i.r.p.)
