Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). Executive summary The European Unions eSafety
20、 Initiative in 2003 established the goal to reduce the number of road fatalities by 50 % up to the year 2010. According to some accident studies referred to in TR 102 664 i.9, rear-end collisions dominate in collision statistics. The 2ndMandate of the European Commission on SRR i.4 calls for alterna
21、tive regulatory options for short range radars. The proposed regulation is based on the existing 24 GHz NB radar operating in the 24,05 GHz to 24,25 GHz band and is related to a supplementary mode for an extension band which ranges from 24,25 GHz to 24,50 GHz and operates with a low-activity factor.
22、 In certain driving situations, this supplementary mode will be activated. It extends the usable radar bandwidth from 200 MHz (ISM Mode) to 450 MHz (WLAM Mode). WLAM is seen as being complementary to existing regulations for automotive radar applications. This regulatory solution does not compete wi
23、th long range solutions which can be addressed by 77 GHz to 79 GHz. The addition of the WLAM extension mode to the present 24 GHz NB radars will minimize the investment required. The present document describes the need for an improvement of the existing 24 GHz NB automotive radars. The following inf
24、ormation is important to note: 1) The 24 GHz NB technology has been successfully deployed since it covers most of the short/mid-range driving assistance and safety features required to the front and rear of the car, based on a 200 MHz bandwidth. 2) Many car-makers have invested in the 24 GHz NB tech
25、nology which is in line with the frequency allocation strategy defined by the CEPT and European Commission. 3) The WLAM mode will improve the 24 GHz NB technology in specific driving situations, where a larger bandwidth is required to discriminate specific targets such as pedestrians in parking lots
26、 or cities. 4) The WLAM mode is expected to comply with the protection of the passive services between 23,6 GHz to 24 GHz. 5) The WLAM mode is not seen to impact the fixed services implemented between 24,5 GHz and 26,5 GHz. 6) The WLAM mode is using a bandwidth also designated for SAP/SAB temporary
27、applications, which are unidirectional fixed links. 7) The radar technology is available. A short term safety benefit can be achieved at a limited add-on development cost. Add-on system cost due of additional sensors for front radar WLAM activation and pedestrian recognition and time for the impleme
28、ntation of these technologies are not regarded in the present document. ETSI ETSI TR 102 892 V1.1.2 (2011-07) 6Introduction The present document has been developed to support the co-operation between ETSI and the Electronic Communications Committee (ECC) of the European Conference of Post and Teleco
29、mmunications Administrations (CEPT) for internal reference within ETSI. The European Commission has issued a new Mandate i.4 to the ECC related to automotive Short Range Radars (SRR), whose purpose is divided in two different parts. Part 1 of the Mandate is linked to the fundamental review as define
30、d in EC Decision 2005/50/EC i.1 related to the harmonization of the 24 GHz range radio spectrum band for the time-limited use by automotive short-range radar equipment in the community. According to Part 2, this mandate also requires studies regarding alternative solutions for radar-based road-safet
31、y applications. An open question raised is on: “CEPT is mandated to, where any alternative bands are to be considered for automotive short-range radar systems, propose appropriate technical and regulatory measures to ensure the protection of existing radio services in or near any such bands.“ ECC WG
32、FM has requested ETSI TC ERM to create an ETSI System Reference document on WLAM. ERM#39 adopted a new work item for the creation of such an ETSI System Reference document. The present document is intended to deliver the technical characteristics necessary to describe the spectrum needs, the expecte
33、d usage scenario and technical performance and implementation aspects for 24 GHz WLAM equipment. In addition, related market information is provided. ETSI ETSI TR 102 892 V1.1.2 (2011-07) 71 Scope The present document provides information on short range device equipment using the Wideband Low Activi
34、ty Mode (WLAM) and operating in the frequency range from 24,05 GHz to 24,50 GHz noting that the WLAM mode is activated in certain use cases. The primary application focus is pedestrian detection and protection. The present document includes the necessary information to support the co-operation betwe
35、en ETSI and the ECC including: market information; technical information; regulatory issues. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For non-speci
36、fic references, the latest version of the reference document (including any amendments) applies.
