IARU Administrative Council Considers New Radio Spectrum Pollution Threat

(It’s not easy being green…) The Administrative Council (AC) of the International Amateur Radio Union (IARU) believes high-power wireless power transfer (WPT) for electric vehicles has significant potential to interfere with radio communication. That assessment came as the AC met on September 15 and 16 in Landshut, Germany, immediately prior to the IARU Region 1 Conference, to review its priorities and positions with regard to the 2019 World Radiocommunication Conference (WRC-19). Conference Agenda Item 9.1.6 would call for studies in advance of WRC-23 to assess the impact of WPT for electric vehicles on radiocommunication services and to study suitable harmonized frequency ranges to minimize its impact. The AC determined that addressing the threat requires an increased commitment of resources by potentially affected radiocommunication services, including Amateur Radio. The WPT issue came up earlier this month at the meeting of CEPT WRC Project Team D, held in Vilnius, Lithuania, the week of September 11. At that gathering, IARU addressed the impact of spurious emissions from proposed high-power WPT systems for electric vehicles. As the ITU explained in its August 2016 report, "Applications of wireless power transmission via radio frequency beam," WPT technology is considered a game-changer. "We will be able to become free from lacking electric power when electric power will be supplied wirelessly," the report said. WPT vehicle applications typically use frequencies in the LF and MF range. In addition to WPT, the WRC-19 agenda includes several other items of potential concern to radio amateurs and a possible allocation in Region 1 of 50-54 MHz to the Amateur Service to harmonize with the allocations in the other two International Telecommunication Union (ITU) regions. Delegates reviewed and updated the strategic plan to develop support for amateur spectrum allocations in 2016-2020, and they approved action plan for the remainder of 2017 and 2018. They also reviewed and adopted the IARU 2018-2020 budget, based upon anticipated financial contributions from the IARU International Secretariat and the three regional organizations. The budget adopted reflects ongoing efforts to minimize expenses. Regional representatives on the AC reported progress in their areas, including the successful Amateur Radio Administration Course, a course attended by administrators from several Latin American countries that was offered earlier this year in Mexico City. Tore Worren, LA9QL, was appointed as EMC Coordinator, replacing Thilo Kootz, DL9KCE, who has had to step down because of a change in employment. =ARRL Letter
