Status Report of CEPT Spectrum Management Actions Related to Automotive/Vehicular Radars Thomas Weber, ECO Spectrum Management 360° Surround Automotive Radar, 7-9 May 2012
Content Automotive/Vehicular radar frequencies Current Revision of the Regulations ERC Recommendation 70-03 Annex 5 Withdrawal ECC/DEC/(02)01 World Radio Conference 2015 Applicable CEPT/ECC Reports
Wireless Medical Applications - Frequencies Frequencies for vehicular/ automotive radars are identified in ERC Recommendation 70-03 Annex 5. –This Annex 5 covers frequency bands and regulatory as well as informative parameters recommended for Road Transport and Traffic Telematics (RTTT) including all types of vehicle communications between vehicles (e.g. car-to-car), and between vehicles and fixed locations (e.g. car-to-infrastructure) as well as radar system installations to be used in ground based vehicles. They are regulated by ERC Recommendation 70-03 (Annex 5) and by ECC Decision 2004/545/EC for 79 GHz and in EC Decision 2005/50/EC, amended by 2011/485/EU, for 24 GHz.
Current Revisions in CEPT in relation to Automotive Radars ERC Recommendation 70-03 Annex 5 – approved (27 April 2012) ECC Decision (04)10 – for approval by ECC in May 2012 Withdrawal of ECC Decision (02)01 - in public consultation (76-77 GHz included) 76-77 GHz railway radars in ERC Rec. 70-03 Annex 4 – in public consulation Fifth Update of the EC Decision for SRD (EC wants CEPT to investigate widening of the scope of ERC REC 70-03 Annex 5 applications) – EC Decision 2006/771/EC -> incl. 76-77 GHz
ERC Recommendation 70-03 Annex 5 Vehicular/Automotive Radars - SRR d121.65-26.65 GHz***ECC/DEC/(04)10For automotive Short Range Radars (SRR) * See detailed requirements in related ECC Decision. New SRR equipment may only be placed onto the market until 1 July 2013 d224.25 -26.65 GHz***ECC/DEC/(04)10For automotive Short Range Radars (SRR) See detailed requirements in related ECC Decision. SRR equipment may only be placed onto the market until 1 January 2018. This date is extended by 4 years for SRR equipment mounted on motor vehicles for which vehicle conformity compliance has been granted before 1 January 2018 e 77-81 GHz***ECC/DEC/(04)03For automotive Short Range Radars (SRR) * See detailed requirements in related ECC Decision Comparable technical specifications to those given in these ECC Decision are given in EC Decision 2004/545/EC for 79 GHz and in EC Decision 2005/50/EC, amended by 2011/485/EU, for 24 GHz. Harmonised EU Standards under the R&TTE Directive: EN 302 288 (24 GHz) and EN 302 264 (79 GHz) -> Installation Requirements
ERC Recommendation 70-03 Annex 5 Vehicular Radars – LRR - and fixed installed radars c 76-77 GHz55 dBm peak e.i.r.p. No requiremen t No spacing 50 dBm average power or 23.5 dBm average power for pulse radar only. For vehicle radars The frequency band is also included in Annex 4 d 76-77 GHz55 dBm peak e.i.r.p. No requirementNo spacing Obstruction/Vehicle detection via radar Sensor at railway level crossings 50 dBm average power or 23.5 dBm average power for pulse radar The frequency band is also included in Annex 5 Also used by fixed installed radars at railway level crossings (Annex 4 of REC 70-03): Other fixed radar installations would need spectrum engineering studies with positive conclusions in the CEPT before they could be allowed (Risk of interference to vehicular radars -> evidence provided by the Mozarim Study). Both applications covered by ETSI EN 301 091 (under revision) – Installation Requirements for fixed radars
ERC Recommendation 70-03 Annex 5 Narrowband Radars f1 24.050-24.075 GHz100 mW e.i.r.p. No requiremen t For vehicle radars f2 24.075-24.150 GHz0.1mW e.i.r.p. No requiremen t For vehicle radars 100 mW e.i.r.p. 4µs/40kHz dwell time every 3ms For automotive radars The spectrum access and mitigation requirement is given for devices mounted behind a bumper. If mounted without a bumper, the requirement should be 3µs/40kHz maximum dwell time every 3ms. A requirement for minimum frequency modulation range (applicable to FMCW or step frequency signals) or minimum instantaneous bandwidth (applicable to pulsed signal) of 250 kHz applies in addition to the requirement on maximum dwell time 1ms/40kHz dwell time every 40ms For automotive radars The spectrum access and mitigation requirement is given for devices mounted either behind a bumper or mounted without a bumper. A requirement for minimum frequency modulation range (applicable to FMCW or step frequency signals) or minimum instantaneous bandwidth (applicable to pulsed signal) of 250 kHz applies in addition to the requirement on maximum dwell time f3 24.150-24.250 GHz100mW e.i.r.p. No requiremen t For vehicle radars Restrictions in 24.075-24.150 GHz: compatibility with speed radars ETSI EN 301 858
ERC Recommendation 70-03 Annex 5 Wideband Low Activity Mode (WLAM) g1 24.250-24.495 GHz -11 dBm e.i.r.p 0.25%/s/25 MHz duty cycle For automotive radars The activity of the Wideband Low Activity Mode (WLAM) is limited to avoid the risk of interference and this mode is only activated in specific configurations as a complementary to designation f1, f2 and f3 as described in ECC Report 164. g2 24.495-24.500 GHz -8 dBm e.i.r.p 1.5%/s/25 MHz duty cycle g3 24.250-24.500 GHz +20 dBm e.i.r.p. 5.6%/s/25 MHz duty cycle +16 dBm e.i.r.p. 2.3%/s/25 MHz duty cycle Complementary to Narrowband Radars The wider bandwidth will be only activated in specific driving conditions, i.e. for pedestrian safety. ETSI EN 301 858 (under revision to include WLAM)
Next World Radio Conference WRC-15 WRC-12 concluded on a new agenda item for WRC-15: –AI 1.18: to consider a primary allocation to the radiolocation service for automotive applications in the 77.5 – 78 GHz range in accordance with Resolution COM6/23 (WRC-12) –COM6/23:76-77 GHz and 77-81 GHz most suitable bands for SRR in the future –76-77.5 GHz and 78-81 GHz are already allocated to the radiolocation service worldwide on a primary basis –This gives SRR applications protection
Where to find information EFIS Database (www.efis.dk): one can search and compare the regulations from 41 European countries. The database contains all the related documents (EC Decision, ECC/ERC Decisions and Recommendations, ETSI SRDocs and Harmonised European Standards), see under European Common Allocation Table, ECA, which is integrated in the EFIS database.www.efis.dk Information about the ETSI-ECC-EC Process: http://www.cept.org/ecc/about- ecc/ecc-etsi (in case of new harmonisation measures needed)http://www.cept.org/ecc/about- ecc/ecc-etsi ECO: see under http://www.cept.org/eco/about-ecohttp://www.cept.org/eco/about-eco Inside the ECC, its the WGFM SRD/MG and WGSE SE24 dealing with vehicular radars (www.cept.org).www.cept.org In addition, ECC/DEC/(02)05 specifies EN 300 086 (analogue!) for UIC DMO and need for interoperability in two considerings of ECC/DEC/(02)05. ECO: there is evidence that the UIC DMO application only exists on paper but not in reality (no equipment found in the market as result of desktop search and questions to the community). Question 1: Can UIC DMO be removed from the ECC deliverables (this includes also ECA – European Common Allocation Table and EFIS Database)?
