  radio spectrum and satellite orbits.
• organised by the ITU every two or three years.

WRC-03

• Agenda
• ITU Council resolution 1156
• Preparation
• Conference Preparatory Meeting (CPM)
• first CPM Istanbul, 7-8 June 2000

Introduction of digital broadcasting service in
the HF bands

• Yes!!!
• When?
• WRC-92 extension bands are allocated to
  broadcasting service as from 1 April 2007
• Fixed and mobile services no longer there!
• Planning criteria?
• New Recommendation on protection ratios.
• Digital will not cause more interference that
  that from the original DSB analogue service

Review of frequency allocations to amateur,
amateur-satellite and broadcasting services
around 7 MHz

• Current situation

7
Review of frequency allocations to amateur,
amateur-satellite and broadcasting services
around 7 MHz

• Main results of analysis
• important national and international applications
  of FS, MS and AS
• spectrum sharing between AS and BS undesirable
• AS requires 300 kHz in Region 2
• sharing between AS/FS/MS possible

8
Review of frequency allocations to amateur,
amateur-satellite and broadcasting services
around 7 MHz

• Possible solution A

9
Adequacy of the frequency allocations for HF
broadcasting from 4 MHz to 10 MHz.

• Current situation
• additional 250 kHz required to eliminate
  co-channel collisions
• additional 800 kHz required to eliminate co and
  adjacent channel collisions
• study based on information through regional
  coordination groups ABU-HFC, ASBU and HFCC

10
Adequacy of the frequency allocations for HF
broadcasting from 4 MHz to 10 MHz.

• Possible solution
• further studies to WRC-05/06
• WRC-05/06 to consider allocations from
• 4.500-4.650 kHz
• 5.060-5.250 kHz
• 5.840-5.900 kHz
• 7.350-7.650 kHz
• 9.290-9.400 kHz
• 9.900-9.940 kHz
