IARU notes progress toward 50 MHz Region 1 allocation

The IARU have released a statement on progress towards getting a 50
MHz allocation for the Amateur Service (but not the Amateur Satellite
Service) in Region 1

Significant progress was made in preparing for the World
Radiocommunication Conference in 2019 (WRC-19) at a two-week meeting
at the International Telecommunication Union (ITU) in Geneva in
November 2017.  However, there remains a lot to do before the
reservations and concerns of regulators and spectrum users are
adequately satisfied.

The team representing IARU in Working Party (WP) 5A of the ITU
Radiocommunication Sector (ITU-R) consisted of amateurs from
Australia, Brazil, Canada, Germany, Ireland, Japan, Norway, the
Netherlands, United Kingdom and the United States.

For IARU the main focus was on the WRC-19 agenda item which will
consider a frequency allocation for the amateur service in Region 1
from 50 to 54 MHz similar to Regions 2 and 3. The current, mainly
secondary, allocation 50-52 MHz in most European countries is a
regional agreement. During the meeting input documents from IARU,
France, the Russian Federation and Switzerland were considered with
the following intermediate results:

• A rough consensus was achieved on the text which will provide the
technical basis for discussions concerning the access to 50-54 MHz for
the amateur service in Region 1.

• A method for calculating the spectrum needs of the amateur service
in 50-54 MHz was proposed by IARU and has been accepted by some
administrations.  More information to justify the requested bandwidth
however will be required.

• For sharing studies particularly in relation to the land mobile
service and radiolocation applications in 50-54 MHz, a mutually agreed
propagation model remains to be determined.

• No major objections to sharing with analogue television broadcasting
in 50-54 MHz in Region 1 remain, provided that a time limited field
strength limit is applied.

In addition to an amateur allocation in Region 1 at 50 MHz other key
issues for the amateur service at WRC-19 include securing protection
for amateur service primary allocations at 24 GHz and 47 GHz and
minimising possible interference arising from Wireless Power
Transmission for the charging of electric vehicles.

Following the meeting of Working Party 5A and other meetings related
to the work of ITU-R Study Group 5 the ITU hosted the first of three
planned Inter-Regional Workshops on WRC-19 Preparation. IARU Vice
President Ole Garpestad, LA2RR, who also attended the WP 5A meeting,
represented the IARU at the workshop to hear reports on progress by
the regional telecommunications organizations.
