• MEASAT-2 at orbital location of 148East
• AFRICASAT-1 at orbital location of 46East

5
SKMM ROLE

• Ensure availability of radio frequency spectrum
  for Malaysian satellites
• Protect existing frequency assignments for
  Malaysian users
• Issuance of frequency assignments to users
  through Apparatus assignment or spectrum
  assignment.

6
INTERNATIONAL REGULATION

• Articles 9 and 11 of Radio Regulations of ITU
  specifies procedures before any satellite network
  is brought into use (notification and
  registration).
• ITU maintains a Master International Frequency
  Register (MIFR), for radio frequency assignments
  and associated orbital locations.
• Requirement by international treaty for
  coordination and notification.
• Objective is to allow satellite network operates
  intended frequency bands and orbital positions
  without causing interference from/to foreign
  satellite networks within the specified
  coordination arc.

HIGHLIGHT OF WRC-2007 DECISIONS RELATING TO
SATELLITE SERVICE

• Worldwide Plan for fixed-satellite service (FSS)
• WRC-07 revised the technical and regulatory
  provisions for fixed-satellite service in the 800
  MHz bandwidth used in different regions under
  varying climatic conditions for applications such
  as communications, TV, internet, etc. The revised
  Plan, based on the latest technological
  achievements, improves effectiveness of the Plan
  and facilitates access to the spectrum for FSS
  systems.
• Earth-exploration satellite service (EESS)
• WRC-07 extended existing primary frequency
  allocations for EESS, facilitating research and
  exploration of Earth resources and environmental
  elements. This was linked to furthering the
  development of science services. EESS are global
  assets that provide key services to monitor the
  planet as well as to predict and monitor natural
  disasters, meteorology and climate change.
• WRC-07 also approved proposals concerning the use
  and further development of satellite systems
  using highly inclined orbits, high altitude
  platforms, as well as the compatibility and
  sharing between different space and terrestrial
  services.
• International Mobile Telecommunications (IMT)
• Globally harmonized spectrum identified for use
  by International Mobile Telecommunications (IMT)
  represents an important step in the worldwide
  development of IMT systems
• 3.4-3.6 GHz band (no global allocation, but
  accepted by many countries)

12
OTHER RELEVANT ISSUES

• Important for Malaysia to secure frequency bands
  for satellite service and associated orbital slot
  as early as possible since filing priority based
  on first come first served basis.
• The right to use the frequencies and slots is
  after submission of due diligence information to
  ITU.
• Advance planning is necessary as time taken to
  secure the frequencies of 7 years.
