The IARU represents Amateur Radio at CEPT meetings

The *International Amateur Radio Union Region 1* reports that a further
meeting to address the topic of Wireless Power Transmission (WPT) took
place earlier this month. A subgroup of the European Conference of Postal
and Telecommunications Administrations (CEPT) Committee SE24, charged with
work on a report on generic WPT devices, met in Copenhagen, Denmark in
early July.

IARU Region 1 President Don Beattie, G3BJ, provided input on projections of
harmful emissions from WPT systems, both generic and WPT for electric
vehicles, operating at existing harmonic emission limits.

The IARU also reported on tests carried out on small WPT devices and a full
report is to be considered at the next meeting in September. The IARU
continues to argue for tighter emission limits on harmonics and other
spurious emissions from WPT systems, which have the potential to cause
sustained harmful interference to incumbent radio services. The IARU also
was represented at a recent meeting in Switzerland of the CEPT Project Team
D. This was the last of the CEPT project team meetings preparing European
Common Proposals (ECP) for a number of agenda items for World
Radiocommunication Conference 2019 (WRC-19) in October in Egypt.

WRC-19 agenda item 1.1, which addresses the possibility of a "harmonized"
Region 1 allocation at 50 MHz, was the key issue to be resolved. The
project team agreed on the text of an ECP for WRC-19, which, if adopted by
the delegates, would see an entry in the International Table of Allocations
for Region 1, and allocate 50 - 52 MHz to Amateur Radio on a secondary
basis. In addition, the team agreed upon the addition of a footnote to the
International Table to permit individual CEPT countries to introduce a
national primary allocation in the 50,0 - 50,5 MHz sub-band.

The IARU will attend the final meeting of CEPT's Conference Preparatory
Group (CPG) in late August and finalize CEPT's input to WRC-19. That
meeting will also consider a proposal by France to allocate 144 - 146 MHz
to the Aeronautical Service on a primary basis.
