WRC - 97

1. WRC - 97 Overview of Results January 1998

2. LITTLE LEOS (MSS BELOW 1GHz) • Canadian Interests • Proposals • Conference Environment • WRC-97 Results • Impact of WRC-97 Results

3. LITTLE LEOS (MSS BELOW 1 GHz)CANADIAN INTERESTS • Teleglobe has major financial investment in Orbcomm in partnership with Orbital Sciences Corp. • first provider of global LEO satellite data and messaging communications services • SILA Communications, a Canadian system needing access to additional spectrum

4. LITTLE LEOSProposals • Limited allocations made at the previous two WRC’s • Canada submitted proposals to WRC-97: • 3 MHz of global uplink spectrum in 450-470 MHz • 1 MHz for downlinks in 405-406 MHz to come into effect when Met Aids migrate out of the band • to remove certain technical and regulatory constraints from existing MSS allocations to support Orbcomm and SILA • Canadian information paper submitted supporting the feasibility of MSS uplinks sharing with FS & MS • CITEL, USA and Indonesia had proposals for additional MSS allocations

5. LITTLE LEOSConference Environment • Spectrum for Little LEOS contentious topic and linked with other issues • Significant opposition led by Europe and Japan • Worldwide allocations and elimination of constraining footnotes around 149 MHz ruled out early in discussions • Agreement to support the conclusions of the CPM Report to maintain 137-138 MHz pfd • Support outside of Region 2 increased late in the course of the conference

6. LITTLE LEOSWRC-97 Results • Success in maintaining pfd limit in 137-138 MHz band • Limited new uplink allocations made in 450-470 MHz • 454-455 MHz via in-country footnote - Canada, Mexico, Panama & US • 3 MHz allocated in five Region 1 & 3 countries • Additional footnotes to protect terrestrial services sharing these bands • 405-406 MHz identified as a potential down link band • WMO to participate in review of Met Aids use of the band

7. LITTLE LEOSImpact of WRC-97 Results • Limits the potential for new MSS operators, e.g. SILA, to access spectrum • Issues to be addressed further at WRC-99 • Additional studies required on feasibility of sharing MSS with other services with view to obtaining worldwide spectrum and reducing technical and regulatory constraints

8. MOBILE SATELLITE SERVICES BETWEEN 1 TO 3 GHz TOPICS • Canadian interests • Proposals for MSS in the bands 1675-1683 MHz and 1559-1567 MHz • Generic Mobile Satellite at 1.5/1.6 GHz • Harmonization of the 2 GHz MSS allocations

9. CANADIAN INTERESTS • TMI and their MSAT service • CANCOM participation in Globalstar system • Iridium Canada participation in Iridium system • Aeronautical and maritime mobile satellite requirements • Other potentially affected radio services.

10. PROPOSALS FOR MSS IN THE BANDS 1675-1683 MHz AND 1559-1567 MHz • ITU-R studies showed feasibility and conditions for sharing MSS, Met Sat and Met Aids in the band 1675-1690 MHz • Canada made a proposal for MSS in the band 1675-1683 MHz • Insufficient ITU-R studies to support the concept of introducing MSS in the band above 1559 MHz used by the radionavigation satellite service, e.g. GPS • Canada proposed study of feasibility of sharing of MSS and radionavigation satellite service in the band 1559-1567 MHz • Debate centred on the potential impact on the GPS system • Resolved after high level government intervention - result was call for further study

11. GENERIC MOBILE SATELLITE AT 1.5/1.6 GHz • Generic Mobile Satellite issue - modifying specific aeronautical, maritime and land mobile satellite to the "generic" mobile satellite service • Issue extensively discussed at WARC-87 and WARC-92 and certain modifications made • At WRC-97, proposals for more complete generic mobile satellite made by many countries (European, Asian, USA) • Canada's position was that it could accept proposals for more complete generic MSS allocations but it wanted provisions for the protection of aeronautical and maritime mobile satellite services

12. GENERIC MOBILE SATELLITE AT 1.5/1.6 GHz Results: • For spectrum previously allocated to AMSS • priority for accommodation of spectrum requirements of AMSS (R) for the transmission of messages with priority of 1 to 6 as defined in Article S44 • priority access within a mobile satellite network • For spectrum previously allocated to MMSS • priority for accommodation of the spectrum requirements of the Global Maritime Distress and Safety System (GMDSS) • priority access for GMDSS within a mobile satellite network

13. HARMONIZATION OF THE 2 GHz MSS ALLOCATIONS • Informal consultations indicated no support for the US and Canadian proposals for adding Region 2 MSS allocations, 1980-2010 / 2170-2200 MHz to worldwide allocations • Determined opposition to the above from Europe and many other areas • Canada decided to concentrate on advancing the date of entry for the Region 2 allocations • date advanced from the year 2005 to 2002 - but retention of 2005 by country footnote in a number of Region 2 countries may limit its usefulness.
