IARU delegates from around the world attended the ITU Conference Preparatory meeting for WRC 2019, which took place in February 2019.

This report covers the CPM19-2 meeting in Geneva which was held between 18/2/2019 and 28/2/2019. The purpose of the meeting was to revise the ‘Draft CPM Report’ which contains the initial negotiating positions for work at WRC-19. It is important that the amateur service influences development of the text so that the interests and needs of the amateur service are reflected as much as possible. The CPM report is a complex document of approximately 700 pages and it covers all of the WRC-19 agenda items; the CPM is more-or-less the conclusion of the continuous work on all these agenda items over almost 3 years since the previous WRC. This short report only focuses on what are thought to be the main issues for the amateur service at WRC-19, noting that other issues may arise before and during WRC-19.

The specific amateur item for WRC19 is agenda item 1.1 covering a possible 6 m allocation in ITU-R Region 1. Sub-working group 5A (SWG5A) chaired by Dale, VK1DSH from Australia, was assigned the task of revising the CPM text for this agenda item. Over several days of meetings, the draft CPM text was revised using material from input contributions submitted by ITU members including IARU and text developed during the WP5A/SW1 meetings. The end result was four methods going forward to WRC-19 which may be used to address the agenda item. The methods span from a 4 MHz primary allocation through a mix of primary and secondary allocations to several secondary allocations ranging from 200 kHz to 2 MHz in addition to the “no allocation at all” alternative. The meetings were challenging because of strong opposition to a reasonably sized and primary allocation by a number of administrations and ITU members.

Agenda item 9.1.6 covers Wireless Power Transmission for Electric Vehicles (WPTEV) and the current status is that it’s likely that no changes will be made to the Radio Regulations. This situation doesn’t remove the threat to the amateur service; it more likely means that the focus of the amateur service efforts will need to move to Regional Telecommunications Organisations and to standards organisations including CISPR (which sets emission limits).

Agenda item 1.16 covers RLAN spectrum and might impact the 5650 – 5850 MHz amateur band. One of the proposed methods overlaps the amateur allocation above 5725 MHz and if this method is adopted by WRC-19 then there may be issues for the amateur service.

Agenda item 1.13 covers new spectrum for IMT in the bands above 24 GHz. The band most likely to be impacted is our primary allocation 47 – 47.2 GHz and potentially our allocations around 77 GHz. No sharing studies of the 47 GHz band were conducted during the study period; however, even if the 47 GHz band escapes attention at WRC-19 it may very well come up as an agenda item for WRC-23 so we will need to be prepared to defend the band in the future.

It is important to remember that although this was the CPM set out to present all possible solutions (methods) to the various agenda items, the WRC can make its own decisions regarding band allocations irrespective of agreed CPM methods. It is therefore important for IARU to fully participate in negotiations at WRC-19 to obtain the best possible outcome for the amateur and amateur satellite services.
