AGENDA ITEM 1.2 (Issues B & C)
•
WHAT:
•
•
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:
•
•
Issues addressing sharing between passive remote sensing
satellite systems for Earth observation and meteorology and
fixed mobile communication system
Non-mandatory limits to protect remote sensing
OUTCOME:
•
Combination of non-mandatory and mandatory limits based on
feasibility and importance of protection
• Issue B 10-10.68 GHz (Non-mandatory in-band limits on FS and MS)
• Issue C 36-37 GHz (Mandatory in-band limits on FS and MS)
AGENDA ITEM 1.3
• WHAT:
 Provide a primary allocation to the radiolocation service, contiguous
across
8500-10 000 MHz
 Provide a worldwide contiguous primary allocation to meet the
requirements of EESS (active) systems
• WHY:
• Changes in technology and emerging requirements for increased
image resolution and range accuracy necessitate wider contiguous
bandwidths
• U.S. POSITION:
• Upgrade RL service to primary in 9000-9200 MHz, 9300-9500 MHz
• Allocate additional 200 MHz to EESS &SRS (active) in 9300-9500
MHz
• OUTCOME:
– ADD Radiolocation 9000-9200 MHz and 9300-9500 MHz
– ADD Primary EESS (active) and SRS (active) 9300-9500 MHz and
secondary EESS active) and SRS (active) 9800-9900 MHz

GHz
• Spectrum requirement of approx. 1800 MHz per operator
• IMT satellite requires additional spectrum. The integrated
MSS/terrestrial system is a method of providing MSS
services over a wide area using a space station integrated
with terrestrial infrastructure (e.g., satellite for rural area
and terrestrial stations for metropolitan area)
• WHY:
• Need additional spectrum for 3G/advanced multimedia
devices
• Manufacturers/Operators need international regulatory
framework to introduce new services
• Need international recognition of Integrated MSS/terrestrial

• To consider possible changes in response to Resolution
86 (Rev. Marrakesh, 2002) of the Plenipotentiary
Conference: “Advance publication, coordination and
notification and recording procedures for frequency
assignments pertaining to satellite networks” in
accordance with Resolution 86 (WRC-03)

•
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
AGENDA ITEM 1.13 – HF Issues (continued)
• U.S. POSITION:
•
•
•
To support a new agenda item for large bandwidth
HF systems
To support footnotes on the use of digital systems in
maritime mobile analog allotments and a new
agenda item to study permanent changes to the
maritime mobile allotment plans
No new allocations for the broadcasting or amateur
services
• OUTCOME:
•
No new allocations were approved for the
broadcasting service or the amateur service.
AGENDA ITEM 1.14 – GMDSS & AIS
• WHAT:
• Operational procedures and requirements of the Global Maritime
Distress and Safety System (GMDSS) and Automatic
Identification System (AIS)
• WHY:
• Consequential changes to international radio regulations to take
into account current operating procedures for Safety of Life at
Sea (SOLAS) vessels and introducing additional AIS spectrum
• U.S. POSITION:
• Changes required to meet SOLAS requirements and to better
serve U.S. maritime interests
• Supported additional AIS satellite allocation
• Supported changes to AIS protection levels
• OUTCOME:
• Allocation recognizing AIS transmitters on ships
• Exclusive allocation of maritime DSC distress channel
• Licensing for recreational boaters
AGENDA ITEM 1.15 – Amateur Issues
• WHAT:
• Secondary allocation to the amateur service in band 135.7-137.8
kHz
• WHY:
• Amateur service required additional spectrum on an international
basis in the VLF portion of the spectrum
• ISSUES:
• The Arab group was opposed to such an allocation
• U.S. POSITION:
• The U.S. remained neutral on this issue. 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
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.
AGENDA ITEM 1.17
• WHAT:
• Protection of existing services in all Regions from
NGSO networks in the FSS using bands around 1.4
GHz on a secondary basis
• WHY:
• Passive services in 1400-1427 MHz could receive
harmful interference
• U.S. POSITION:
• Suppress secondary allocation for feederlinks to
NGSO networks in the FSS bands around 1.4 GHz
• OUTCOME:
• Footnote was suppressed
AGENDA ITEM 1.18 – HIO
• WHAT:
• Sharing between FSS using highly-inclined orbit (HIO) and
FS in 17.7-19.7 GHz band
• WHY:
• The appropriate pfd limits for FSS HIO in 17.7-19.7 GHz
band
• U.S. POSITION:
• No Change. HIO is a type of NGSO, and the current pfd
limits applied to NGSO are adequate to protect the FS
• OUTCOME:
• New pfd limits for HIO systems filed after WRC-07
• USCSID-P and future systems using same design
exempted from new pfd limits
AGENDA ITEM 1.19 – Broadband Satellite
• WHAT:

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

• No change. Radio Regulations already accommodate the
ability of FSS systems to provide Internet access
• OUTCOME:
• No change to RR

•
WHAT:
•
•
WHY:
•
•
Incorporate the 1559-1610 MHz (RNSS)/1610.6-1613.8
MHz (RAS) band pair in the Tables in Resolution 739
U.S. POSITION:
•
•
•
Compatibility between the radio astronomy service and
the active space services in adjacent and nearby
frequency bands
Revise Resolution 739 & add band pairs to Tables
Consultation process to protect radio astronomy stations
from unwanted emissions of satellite downlinks if
threshold levels exceeded (Resolution 739 WRC-03)
OUTCOME:
•
WRC-07 adopted a revised Resolution 739 that included
threshold values limiting out-of-band emissions into the
RAS band at 1610.6-1613.8 MHz from RNSS at 15591610 MHz
