31、 document takes forward previous CEPT/ECC Decisions and Recommendations relating to millimetric communications for Transport Telematics applications, and makes the case for the use of the 63 GHz to 64 GHz band for all applications that are generally included in this description. The proposals are ba
32、cked by the work currently being done by a range of companies who have an integrated plan to realize a “next generation road vehicle communication“ system in the immediate future. The present documents objectives are to: a) demonstrate that the need for high data rate communications in the millimetr
33、ic band is a real and growing one; b) provide justification for the continued designation in Europe of 63 GHz to 64 GHz; c) illustrate the advantages of the use of the 63 GHz to 64 GHz band, in respect of: i) the ability to form and control beam patterns resulting from the small wavelength and thus
34、viable size of antennas, the advantage this brings in respect of control of exposure of radiations to users and other humans and animals, and in respect of channel optimization, and in respect of geographic re-use of bandwidth, and in respect of certainty of delivery of (and elimination of false del
35、ivery) of data to intended users; ii) the advantages resulting from oxygen in respect of geographic re-use of bandwidth, and in respect of compatibility issues with other services, and the particular aspects of the Transport Telematics application that suit it to this band. d) illustrate how safety,
36、 management, regulatory and commercial applications can co-exist “symbiotically“, and be combined to deliver ALL applications more readily (in respect of timescales and financially) and to show the enormous economic benefit that this approach will bring; e) describe the technical aspects of the prop
37、osed usage and the items requiring standardization. 4.1 Status of the system reference document ERM-RM#32 created a new work item for TR 102 400 (SRDoc for ITS/RTTT in 63 GHz to 64 GHz). The present document is the result of this decision, and updates and replaces all previous work and documents reg
38、arding ITS RTTT in 63 GHz to 64 GHz. Version 1.2.1_1.1.2 was created and agreed at the ERM TG37#10 meeting; version 1.2.1_1.1.5 has taken account of subsequent comments from ETSI members and was also reviewed and finally adopted by ERM RM#32. The present document was forwarded to WG FM for considera
39、tion. After incorporating editorial it is reduced pro-rata for emissions having a bandwidth of less than 100 MHz. ETSI ETSI TR 102 400 V1.2.1 (2006-07) 9 6 Proposed regulations It is proposed that CEPT adopt power levels for the 63 GHz to 64 GHz band as shown in table 2 and include these in annex 5
40、of CEPT/ERC Recommendation 70-03 1.

41、g ECC DEC(02)01 2 Vehicle-to-vehicle and road-to-vehicle systems Measured over any continuous period of 53 seconds. The maximum peak transmitted power is for an emission bandwidth of greater than 100 MHz. It is reduced pro-rata for an emission bandwidth less than 100 MHz In addition, it is proposed
42、that the title of annex 5 of CEPT/ERC Recommendation 70-03 1 (currently “Road Transport and Traffic Telematics (RTTT)“) and its scope be changed to include the term “Intelligent Transport Systems (ITS)“. Further information and justification on the need to have the set of parameters as shown in tabl
43、e 2 is given in clause B.2.1. 7 Main conclusions A fast and versatile ITS communication system is needed to support the large number of RTTT and other applications (please see clause A.1.2) that have been identified. Systems are now being developed in support of this, making use of several bearer fr
44、equencies, including millimetre wave. The ISO standards group TC204 WG16.1 has prepared and successfully balloted a specification (ISO/CD 21217) 11 for an architecture which will link applications to an appropriate bearer or bearers, depending on what each has to offer at a given time in a given sit
45、uation. This will shortly become a full ISO /IEC Standard. It is recognized that all bearers cannot support all applications, and that there will be circumstances which favour one over another. Millimetric systems in the 63 GHz to 64 GHz part of the spectrum can offer communications with a high data
46、 rate, typical ranges up to 1 km, a low reuse distance and minimal interference from and to other users, together with versatile frequency planning because of the available bandwidth. In addition, they can offer a method of obtaining redundancy when used with other systems for more safety-critical a
47、pplications. Prototypes became available in November 2005, and specialized short range demonstrators are expected in the near future. 8 Expected ECC actions ETSI requests ECC to consider the present document, which includes necessary information to support the co-operation under the MoU between ETSI
48、 and the Electronic Communications Committee (ECC) of the European Conference of Post and Telecommunications Administrations (CEPT) for amending the CEPT/ERC Recommendation 70-03 1. ETSI requests that the ECC consider adopting the power levels in table 2 for inclusion in CEPT/ERC Recommendation 70-0
49、3 1, annex 5 and also consider changing the title and scope of that annex to include the term “Intelligent Transport Systems (ITS)“.
