3.2. Specific technical requirements for vehicular access systems using trigger -
before -transmit  
Technical requirements to be used within the bands 3.8-4.2 GHz and 6 -8.5 GHz for vehicular 
access systems using trigger -before -transmit are defined in the following table.

‘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 mitigatio n 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 p rovide 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 o f 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

6. MATERIAL  SENSING  DEVICES  USING  UWB  TECHNOLOGY   
6.1. Introduction  
UWB material sensing devices are split into two classes:  
- 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 set out  in sections 6.2 and 6.3.   
EN 9  EN The generic UWB regulation  set out in section 1  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 mater ial 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 o f 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 f requency ranges, applies.  
6.2. Contact based material sensing devices  
The specific limits for maximum mean power spectral density (e.i.r.p.) and maximum peak

below the maximum e.i.r.p. spectral density.  
3 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 radiated power spectral density must be below -65 dBm/MHz.

technique are permitted to operate with a maximum mean e.i.r .p. spectral density of -41.3 dBm/MHz and a

EN 12  EN 1 Devices using the 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 set out  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.  
2 To protect the radio services, non -fixed i nstallations must fulfil the following requirement for total 
radiated power spectral density:  
a) In the 2.5 GHz to 2.69 GHz and 4.8 GHz to 5 GHz frequency ranges, the total radiated power spectral 
density must be 10 dB below the maximum e.i.r.p. spectral d ensity.  
b) In the 3.4 GHz to 3.8 GHz frequency ranges, the total radiated power spectral density must be 5 dB 
below the maximum e.i.r.p. spectral density.  
3 To protect the RAS in the 2.69 GHz to 2.7 GHz and 4.8 GHz to 5 GHz bands, the total radiated power 
spectral density must be below -65 dBm/MHz.  
4 Limitation of the duty cycle to 10 % per second.  
5 No fixed outdoor installation is permitted.  
6 Within the 3.1 GHz to 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 a nd its limits are set out  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.  
7 Within the 3.1 GHz to 4.8 GHz and 8.5 GHz to 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 set out  in 
clauses 4.5.1.1, 4.5.1.2 an d 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 2 014/53/EU and respect the technical 
requirements of this Decision. When DAA is implemented, note 5 applies.  
Peak power threshold values for the LBT mechanism to ensure the protection of radio 
services listed below are set out  in the following table.  
Techni cal requirements of the LBT mechanism for material sensing devices  
Frequency range  Radio service to be detected  Peak power threshold 
value  
1.215 <f ≤ 1.4 GHz  Radiodetermination service  +8 dBm/MHz  
1.61<f ≤ 1.66 GHz  Mobile satellite service  -43 dBm/MHz  
2.5 < f ≤ 2.69 GHz  Land mobile service  -50 dBm/MHz  
2.9 < f ≤ 3.4 GHz  Radiodetermination service  -7dBm/MHz  
  
EN 13  EN Additional requirements for radar detection: continuously listening and automatic switch -off 
within 10  ms for the related frequency range if the threshold value is exceeded (table with 
LBT mechanism). A silent time of at least 12  s while listening continuously is necessary 
before the transmitter can be switched on again. This silent time during which only the  LBT 
receiver is active must be ensured even after the device is switched off.
