6、)/Amd.3 (02/2013) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is re
7、sponsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by th
8、e ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collabor
9、ative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain
10、mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirement
11、s. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU
12、 takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual p
13、roperty, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

15、3 Appendix I New version v.3.0.3 of the EMF-estimator software (This appendix does not form an integral part of this Recommendation.) Amendment 3 to Recommendation ITU-T K.70 (2007) was agreed on 7 February 2013 by ITU-T Study Group 5 (2013-2016). This amendment consists of a new version (v.3.0.3) o
16、f the EMF-estimator software, which constitutes Appendix I of Recommendation ITU-T K.70. The main improvements introduced in v.3.0.3 are the following: import of the antenna patterns directly from the websites of Kathrein Inc., Andrew Solutions and Radio Frequency Systems (RFS) is allowed; after cal
17、culation on the horizontal grid, it is possible to add a background in the form of the map loaded from Google maps; the term “cumulative exposure“ has been changed to the term “total exposure“ following discussion and decision taken during the work on ITU-T K.91. Import of the antenna patterns of th
18、e Kathrein, Andrew and RFS transmitting panels The EMF-estimator allows the user to introduce new transmitting antennas, including radiation patterns. However, it is time-consuming. In the new version (v.3.0.3), it is possible to import parameters of the new panels manufactured by Kathrein Inc., And
19、rew Solutions and RFS. In the “Project“ menu there are three new positions under “New radiation pattern Import “. The new menu is presented in Figure 1. 2 Rec. ITU-T K.70 (2007)/Amd.3 (02/2013) Figure 1 EMF-estimator new import positions in the menu The new positions of the menu allow for direct imp
20、ort of the files downloaded from the websites of the Kathrein Inc., Andrew Solutions and RFS webpages. The proper links are presented below: Kathrein (csv or MSI format) http:/www.kathrein.de/svg/index.cfm?sprache=en http:/kathrein- Andrew (MSI format) http:/ RFS (Planet MSI format) http:/ It should
21、 be noted that access to certain data requires registration. It is planned in the future to add to the EMF-estimator the automatic import procedure of additional antenna data, accessible using the webpages of other manufacturers. Result of grid calculation on the background Google map In the new ver
22、sion of the EMF-estimator, it is possible to expand the result of the horizontal grid calculation by the background loaded from the Google maps. It requires the input of the coordinates of the transmitting station. Figure 2 presents an input screen with the fields of the geographic coordinates, and
23、Figure 3 provides an example of a result of calculation on the background of the map. Figure 2 shows the northern “N“ and eastern “E“ part of the Earth. It may be changed by clicking on the letter that should be changed. Rec. ITU-T K.70 (2007)/Amd.3 (02/2013) 3 Figure 2 Example result of EMF calcula
