5. www.gvf.org The Reality

6. www.gvf.org Why is Interference Increasing?

7. www.gvf.org Characterizing Interference Types Note: Percentages are based on Intelsat's experience but are indicative of hundreds of interference events experienced by the world’s satellite operators.

8. www.gvf.org Satellite RFI: Breaking It Down Problems: 1.Improper Installations 2.Sub-Standard Equipment 3.Unidentified Carriers 4.Wireless Interference 5.Information Sharing 6.Disfunctional Networks 7.Skills Deficit Solutions: Training & Certification Product Quality Assurance Carrier ID Spectrum Initiative SDA Network Validation Benchmarking

11. www.gvf.org Global Training Status More Than 10,000 Technicians Enrolled Worldwide Training Centres Established in Every Major World Region Multiple Languages Via 70+ Examiners and Instructors Worldwide Curriculum for SOTM, Auto-Deploy, Fixed VSAT, Maritime, etc.

12. www.gvf.org Sub-Standard Equipment Trends 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 Now, Auto-Deployand SOTM Is Being Added to the Mix Vacuum in Technical Know-How and Deployment of Systems That Spray Orbital Arc with Interference
