The Conference Preparatory Meeting (CPM) Report on technical, operational and regulatory/procedural matters to be considered by WRC-19 is available for download

The World Radiocommunication Conference 2019 (WRC-19) takes place in Sharm el-Sheikh, Egypt, 28th October to 22nd November 2019.

The Amateur Service 50 MHz allocation is one of the items on the agenda.

Agenda item 1.1

1.1 to consider an allocation of the frequency band 50-54 MHz to the amateur service in Region 1, in accordance with Resolution 658 (WRC-15);

Resolution 658 (WRC-15) – Allocation of the frequency band 50-54 MHz to the amateur service in Region 1

5/1.1/1 Executive summary

This agenda item addresses a possible new Region 1 allocation to the amateur service in the frequency band 50-54 MHz by full or partial worldwide harmonization with the existing 4 MHz primary allocations in Regions 2 and 3.

The spectrum needs for the amateur service has been quantified in two studies using an application-based approach. One of them indicates that 4 MHz of spectrum is required while the other indicates that 1.75 MHz is required.

Administrations in parts of Region 1 are party to the ST6133and GE8934Regional Agreements which remain in force in the band 50-54 MHz.

Studies have been undertaken to assess the possibility of sharing with the incumbent broadcasting, land mobile and radiolocation services. The studies have demonstrated that large separation distances are required for sharing with incumbent services. Furthermore, regulatory provisions will need to be implemented. Depending upon the incumbent service to be protected, the different protection distances and some measures can be found in Report ITU-R M.[AMATEUR_50_MHz].

Four methods are provided to satisfy the agenda item including the No Change method:

Method A: An allocation to the amateur service on a primary basis in Region 1 in the band 50-54 MHz, or part thereof;
Method B: An allocation to the amateur service on a secondary basis in Region1 in the band 50.080-50.280 MHz, (Method B1), or in the band 50-52 MHz (Method B2);
Method C: An allocation to the amateur service in Region 1 on a partly primary and partly secondary basis in all or part of the frequency band 50-54 MHz;
Method D: No changes in the frequency band 50-54 MHz.

Regulatory text is also provided for implementation of the proposed methods.

5/1.1/2 Background

In ITU Region 1, the frequency band 50-54 MHz is allocated to the broadcasting service on a primary basis, with additional or alternative allocations to the amateur, fixed, mobile, and/or radiolocation limited to wind profiler radars (WPR) services in some countries.

The frequency band 47-68 MHz in most of Region 1 is governed by the ST61 and GE89 Regional Agreements, which remain in force, noting that several countries in Region 1 were not party to the original agreements
