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
