IARU Represents Amateur Radio at WRC-19 Preparatory Meeting

​The International Telecommunication Union (ITU) holds World Radiocommunication Conferences (WRCs) approximately every four years, the next (WRC-19) being scheduled for 28 October to 22 November in Sharm el-Sheikh, Egypt. Each WRC develops an agenda for the next one, along with a preliminary agenda for the one to follow. At a brief Conference Preparatory Meeting (CPM) held immediately after a WRC, assignments are made to Working Parties of the ITU Radiocommunication Sector (ITU-R) to conduct studies and develop methods for satisfying the upcoming agenda items. The Working Parties (WPs) then meet, typically twice a year, to prepare text for a comprehensive draft technical report that is reviewed and finalized at a second, longer CPM held about eight months prior to the WRC. The International Amateur Radio Union (IARU) is a Sector Member of ITU-R and is entitled to participate fully in its WPs and CPMs.

The second CPM for WRC-19 was held in Geneva from 18 to 28 February 2019 and drew more than 1,200 participants from 107 countries. Their task was to review a 780-page (in English) Draft CPM Report and nearly 200 documents proposing changes. Among the participants were nine who attended specifically to represent the interests of the amateur and amateur-satellite services. Two represented the IARU with the remainder serving on their national delegations, but all were connected to the IARU either directly or through their national IARU member-society. The CPM attendees do not comprise the entire IARU WRC team; in all there are some two dozen volunteers from more than a dozen countries who are engaged in WRC preparation on behalf of amateur radio.

Despite the magnitude of the task, the CPM actually completed its work slightly ahead of schedule. Extensive revisions to the draft report were agreed and will be incorporated in the final CPM Report that is to be released by late April. While the technical work was conducted in English, this mammoth document must be translated into each of the other five official languages of the United Nations: Arabic, Chinese, French, Russian, and Spanish.

WRC-19 Agenda Item (AI) 1.1 raises the possibility of an improvement to the six meter band in ITU Region 1, where the international Radio Regulations only include an allocation in a few African countries. Over the past three years this AI has been the focus of most of the IARU’s efforts in ITU-R WP 5A. Methods of addressing the agenda item that are outlined in the CPM Report range from a 4 MHz primary allocation shared with existing services to No Change (NOC), with three others lying between the two extremes. The advantages and disadvantages of each method are described. The WRC itself will only consider proposals that are actually offered by administrations or by regional telecommunications organizations (RTOs), which are likely to be similar to one or more of these methods. No impact on the amateur allocations in Regions 2 and 3 is anticipated.

AI 1.13 is an effort to identify spectrum in bands above 24.25 GHz that may be designated for International Mobile Telecommunications (IMT). Ever since the first terrestrial service allocations above 40 GHz were made in 1979, the band 47-47.2 GHz has been allocated on a primary basis to the amateur and amateur-satellite services to the exclusion of other services. No sharing studies of the 47 GHz band, which normally would be a prerequisite to consideration of a new allocation, were conducted during the study period; however, that has not prevented a belated effort by IMT interests to justify a mobile allocation and IMT designation. Even if the 47 GHz band escapes attention at WRC-19 it may very well come
