Interference Prevention &
Mitigation:
Satcom Trends and Initiatives
David HartshornSecretary General
Global VSAT Forum
The ITU, GVF & Interference Prevention
ITU-GVF Interference-Prevention MoU Established
Facilitating Satcom Worldwide Thru:
– Spectrum Coordination (WRC-15)
– Training & Certification (“100 Islands”)
– Earth Station Testing & Approvals (e.g. SOTM, fixed VSAT)
– Industry Benchmarking (e.g. for HTS Distributors)
– Regulatory & Policy (e.g. Intentional Interference)

What We Want
Served by spotbeam satellites
VSAT Terminals in Millions
Served by "regular" satellite capacity
• Deregulation and improved products drive market acceleration
• New markets such as communications on the move offer new growth opportunities
• Spotbeam satellites are an attractive proposal for a part of corporate needs

Policy?
1. WRC-07: The Global Outcome
WRC-15: A Much Greater Challenge
“The Satellite Industry Will Need Courage to Address the Wireless Industry’s Challenge at WRC-15 Which, Compared with WRC-07, Will be Terrible.”
– Yvon Henri, Chief, Space Services Department, Radiocommunications Bureau of the ITU
The Satellite Industry Is Providing New Data, Consensus-Based Positions, and Other Support for the ICT Community in Preparation for WRC-15

2. Elevating Equipment Standards
• Increasing Attempts by Inexperienced Manufacturers to Try Production of Transmiting VSAT Antennas
•Designers often unaware of how accurately installers must align the antenna to prevent ASI and cross-pol interference
•Providing Testing, Type Approval, Technical Expertise
•The GVF Mutual Recognition Arrangement
3. Preventing Improper VSAT Installations
