Foreword This Technical Report (TR) has been produced by E

18、TSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). The present document presents a revision of V1.1.1. This revision includes: a review of the SRR scenarios developed since the publication of TR 102 664 V1.1.1 as well as recent technical developments of UWB SRR t

19、echnology. Executive summary The present document describes the need for the proposed allocation of the new SRR frequency range for a 26 GHz UWB SRR band from 24,25 GHz to 27,5 GHz. 1) The shortcomings of the present UWB SRR regulation are such that the UWB SRR technology risks discontinuation in th

20、e automotive industry. This is because of the very low SRR penetration caused by the present regulations. The goal of the eSafety program of the European Commission for safety on the roads is at stake since the SRR car penetration has stalled at a low penetration level of 0,02 % with no outlook to i

21、ncrease e.g. over the next 5 years, unless the proposal for the new 26 GHz UWB SRR band is realized. 2) The present document describes a proposal for the 26 GHz UWB SRR band that allows the introduction of SRRs in the proposed range while protecting the passive services. It presents a cost efficient

22、 solution especially avoiding the cumbersome and costly inclusion of deactivation devices around radio astronomy sites. 3) The proposal of the present document fulfils the requirement of the EC Decision 2005/50/EC i.1 for conducting a fundamental review to be completed by 2009. The proposal is creat

23、ed in support of the ECs final mandate to CEPT to undertake studies for alternative frequencies to the 24 GHz range for SRRs i.27. 4) The proposed solution provides the global harmonization for UWB SRRs as pursued by the ITU-R during WRC 2007 within the present range of 24 GHz to 27,5 GHz. Secondly

24、the proposed solution also provides a window for activities to achieve the global harmonization for the 79 GHz UWB SRR band until the production start. This is an essential requirement for the market acceptance and the effective proliferation of the 79 GHz automotive UWB SRRs. 5) The protection requ

25、irements of passive services in the 23,6 GHz to 24 GHz dictate a shift of frequency. Secondly in view of the close deadline and the short design-in cycle needed, the alternative 26 GHz solution, is the only realistic technology to bridge the gap and provide a seamless technology option for the deplo

26、yment of UWB SRRs - otherwise at stake for the car industry. ETSI ETSI TR 102 664 V1.2.1 (2010-04) 66) The industry continues with strong commitment for continued development efforts to productize the 79 GHz SRR technology on the chip, the sensor module level as well as the assembly technology level

27、 for the earliest possible market introduction. The 79 GHz SRR technology provides the optimum performance combined with the synergy option to combine the long range 76 GHz ACC function with the short range surround looking performance in one module (see figure B.1.1). Introduction Over the past yea

28、rs, the industry has responded to European Commission programs and has developed new Short Range Radar (SRR) solutions for Road Safety and Intelligent Transport Systems. This is in support of such programs as eSafety, IST, the EU Approach to Road Safety and Intelligent Transport systems (ITS). Europ

29、ean programs funded by the Community made use of SRR technology, for instance the PREVENT projects as INSAFE, COMPOSE and APALACI i.3. See http:/www.prevent-ip.org. The FP7 programme continues to consider these SRR technologies as a basis for next generation applications i.16. In particular, current

30、 programs as KOKON (vehicle high-frequency electronics), RoCC (Radar on Chip for Cars) aim to design, demonstrate (KOKON) and implement (RoCC) SRR technology for the 76 GHz to 81 GHz band i.31. The objective and focus of “The EU Approach to Road Safety and Intelligent Transport systems (ITS)“, Intel

31、ligent Vehicle Systems are defined as to “improve safety, security, comfort and efficiency in all transport modes“ and “focusing on advanced pilot/driver assistance systems (in support of vision, alertness, manoeuvring, automated driving compliance with the regulations, etc.)“. The current regulatio

32、n 2005/50/EC i.1 is focused on SRRs operating at 24 GHz. The Radio Spectrum Committee discussed part 2.2 of the 2005/50/EC i.1 on SRR in the 24 GHz range i.e. to review the EC Decision by latest 2009: “2. In addition to the review process in paragraph 1, a fundamental review shall be carried out by

33、31 December 2009 at the latest to verify the continuing relevance of the initial assumptions concerning the operation of automotive short range radar in the 24 GHz range radio spectrum band, as well as to verify whether the development of automotive short-range radar technology in the 79 GHz range i

34、s progressing in such a way as to ensure that automotive short range radar applications operating in this radio spectrum band will be readily available by 1 July 2013“. The present document is related to one of the basic elements of the IST program for the automotive sector and is the base for a var

35、iety of SRR applications. The program as established in the present document is needed to enable and further to accelerate the proliferation of Short Range Radar (SRR) under the eSafety program of the EU Commission. The SRR technology otherwise risks to stagnate or to be discontinued. This is becaus

36、e most of the automotive OEMs noted that new SRR product introduction cannot be justified for the introduction of new car lines in view of the 2013 deadline for the 24 GHz band while the introduction of the 79 GHz SRRs is tied to the readiness of the technology which is still under development for m

37、ass market introduction. The present document is created to enable and accelerate the process of introducing the SRRs to the extent that the automotive SRR technology is used in a significant higher percentage of cars. Only a high percentage allows the effective enhancement of safety on the roads. T

38、he most recent report to the Commission on car penetration with SRRs shows that after five years after the production start and release of the 24 GHz UWB regulation, the car fleet penetration has only reached a very low level of 0,02 % with no outlook to increase significantly further i.13. This is

39、in contrast to the anticipated penetration of appr. 4 % to 5 %, 5 years after the market introduction in 2005. Considering the foregoing, the RSCOM document 08_24 i.5 “Third Party document - Request to initiate fundamental review of automotive short-range radar equipment operating in the 24 GHz radi

40、o spectrum band “, indicates that members can testify that the consumer acceptance of 24 GHz SRR is high, providing that the option is offered, but only few automotive manufacturers have offered this option and those that presently do, are reconsidering whether to cancel or further implement it in u

41、pcoming model lines. RSCOM issued a mandate to CEPT consisting of two parts i.27: Part 1: to review of the EC Decision 2005/50/EC i.1 on the “continued relevance of the initial assumptions“ for the use of the 24 GHz band, and consider the 79 GHz developments “barriers“ to the uptake of the 79 GHz ba

42、nd as permanent band for SRRs“ i.6; ETSI ETSI TR 102 664 V1.2.1 (2010-04) 7Part 2: “to undertake studies with regard to alternative approaches to the 24 GHz range for SRR use.“. The present document considers both addressed parts, tries to provide answers and proposes the way forward under the assum

43、ption that the 79 GHz technology still provides the long term SRR solution, for the automotive industry. It is created in support of the Commissions final mandate to CEPT to undertake studies for alternative frequencies to the 24 GHz range for SRRs i.27. Status of the pre-approval draft The present

48、02 664 V1.2.1 (2010-04) 81 Scope The present document provides a proposal for a complementary introduction of a 24,25 GHz to 27,5 GHz (26 GHz band) UWB SRR technology that is supposed to overcome the challenges experienced under the existing regulation. It is to be noted that the existing regulation

49、 for 24 GHz as well as for 79 GHz is not intended to be modified but to be complemented by this new option. The present document applies to Short Range Devices for automotive applications as defined by EC Decisions 2005/50/EC i.1 and 2004/545/EC i.7. It considers the previous SRDoc TR 101 982 i.11, reviews the present regulation for the 24 GHz UWB SRR band, analyses the situation in the automotive and the component supplier industry, addresses cost issues, the market penetration and regulatory shortcomings. Secondly it proposes forwar
