WRC-12 Industry Debrief 23 April 2013 Agenda item 1.23 – Amateur service secondary allocation Presenter: Dale Hughes Agenda item 1.23 > …to consider an allocation of about 15 kHz in parts of the band 415-526.5 kHz to the amateur service on a secondary basis, taking into account the need to protect existing services… > Why? • Sufficiently different characteristics to adjacent amateur service allocations at 137 kHz & 1.8 MHz to ‘fill a gap’. WRC-12 Industry Debrief 23 April 2013 Australia's position going into WRC-12 > Allocation was supported: • Existing users (NDB’s) must be protected from harmful interference. • Protection measures for existing users were agreed. • Due to incumbent users a subset of the band was the most likely outcome so either WRC ‘method’ was acceptable. WRC-12 Industry Debrief 23 April 2013 Progress during WRC-12 #1 > At first, very slow progress at Sub Working Group level. > General agreement between the ‘affirmative’ side about frequency band limits, but… > Strong opposition from a number of countries to any allocation with delaying tactics employed to prevent any progress. WRC-12 Industry Debrief 23 April 2013 Progress during WRC-12 #2 > A ‘drafting’ group was formed to develop a document that contained both positions. > Again more argument and delaying tactics… > Change of CEPT and APG positions meant progress, but reduced bandwidth. > Power limits and geographic spacing limits suggested, resisted… accepted. WRC-12 Industry Debrief 23 April 2013 Progress during WRC-12 #3 > No consensus at Sub Working Group level. > Elevated to Com4 level and passed after discussion. > Attempt by one administration at plenary to impose very restrictive protection measures overcome. > Affirmative position accepted and passed by plenary session. WRC-12 Industry Debrief 23 April 2013 Outcome > WRC outcome is in line with the original Australian position: • A new secondary allocation for the amateur service between 472 and 479 kHz • 5 W e.i.r.p. limit and other protection measures. WRC-12 Industry Debrief 23 April 2013 Future impact: > Will allow the amateur service to develop skills and expertise at medium frequencies. > Will enhance capability for disaster relief and emergency communications. > Provide opportunity for: • research and development of new communications modes to cope with weak signals and high noise levels, • research of propagation characteristics. WRC-12 Industry Debrief 23 April 2013 Thanks go to: > The ACMA for: their leadership, organization and support activities at WRC-12 and the ‘community’ participation process in the WRC preparatory phase. > The Wireless Institute of Australia for its untiring support of the amateur radio service. > The WRC delegates and ARSG members for their support and enthusiasm. > Acknowledging the late Mr. Keith Malcolm.
