  16. AGENDA ITEM 1.13 – HF Issues • WHAT: • Support introduction of advanced HF adaptive systems • Support Introduction of digital systems for the maritime mobile service • Protect existing HF fixed service and mobile service allocations from additional broadcasting service allocations and /or amateur service allocations • WHY: • Advanced HF adaptive systems allow for dramatic increase in HF reuse and also provide new unique services (i.e. HF internet) • Provides much needed system use of frequencies currently designated for obsolete analog systems • Additional broadcasting and/or additional amateur allocations would cause significant interference to existing vital government systems

  17.

The FCC had conducted a NPRM prior to the WRC and decided that this allocation would not be made in the U.S. • OUTCOME: • An international allocation was made with a power limit of 1 Watt e.i.r.p. and a country footnote from the Arab countries exempting use of this frequency band by the amateurs in their territories

  20. AGENDA ITEM 1.16 – MMSI • WHAT: • Operational provisions for Maritime Mobile Service Identities (MMSI) for equipment and other than shipborne mobile equipment • WHY: • Additional MMSI flexibility was required • ISSUES: • Allowing fixed and airborne components could cause potential interference issues. • U.S. POSITION: • This agenda item was originally proposed by the U.S. and was strongly supported as a requirement for international and national search and rescue responsibilities. • OUTCOME: • Obtained flexibility of application of MMSIs for evolving applications of AIS technology, including use on search & rescue aircraft and AIS use as an Aid to Navigation.

  21.

AGENDA ITEM 1.19 – Broadband Satellite • WHAT: • Spectrum Requirement for Global Broadband Satellite Systems • WHY: • Proposed by the Arab League as a means to bridge the “digital divide” by identifying globally harmonized FSS bands for broadband internet applications via satellite • U.S. POSITION: • No change. Radio Regulations already accommodate the ability of FSS systems to provide Internet access • OUTCOME: • No change to RR

  24. AGENDA ITEM 1.20 • WHAT: • Protection of the EESS (passive) from unwanted emissions • WHY: • Vital U.S. interests both in passive sensing and in services that could cause interference (fixed service, radars, fixed-satellite service uplinks, etc.) • U.S. POSITION: • NOC for some bands/services and non-mandatory limits for some bands to protect remote sensing • OUTCOME: • Combination of non-mandatory/mandatory limits based on feasibility and importance of protection.

  26. AGENDA ITEM 7.2 • WHAT: • Future Conference Agenda 2011. • WHY: • Agenda Item 7.2 deals solely with developing a Resolution containing the recommended agenda for the next two conferences (i.e., WRC-11 & WRC-15). • U.S. POSITION: • The United States had several proposals for this agenda item, including both additions and those we wanted to suppress or modify to reduce the risk associated with them.
