Slide 7: Why Spectrum Will Always Matter
Why Spectrum Will Always Matter • There’s never as much as we want • Sharing it successfully is complex and can be costly • We really don’t like to share, do we? 7
Slide 8: Sharing Spectrum
Sharing Spectrum • Spectrum is getting harder to manage – C-Band reallocations in US and Europe – L-Band reallocation in US – MEO and LEO communications satellites globally • The good news: interference mitigation – – Transitioning from slow, labor-intensive and hardware-centric to… – Faster, more a

Slide 11: The Regulatory Challenge
The Regulatory Challenge Why is it important to monitor radio spectrum in today’s ever changing space environment? 1. Detecting, identifying and solving harmful interference: a. detecting that your transmissions QoS is degrading, b. identifying the cause of the degradation (internal/external) c. whe
Slide 12: Regulatory Challenge – Types of Interference
Regulatory Challenge – Types of Interference • Unwanted emissions may interfere with passive sensors o Resolution 750 (Rev.WRC-19) provides unwanted emissions levels aimed at ensuring compatibility between the Earth exploration-satellite service (passive) and adjacent or nearby active services. • In

Slide 20: The Growing Interference Challenge
The Growing Interference Challenge Millions of VSATs RF interference issues: • More complex 100+ New HTS Hundreds of GEO Satellites • More price sensitive • Increasing impact on SLAs Spectrum is a shared resource Closer Thousands Proximity Of SmallSats 20
Slide 21: Need to Rethink Spectrum Monitoring
Need to Rethink Spectrum Monitoring • Multi-satellite and dynamic frequency plan – Software defined network • Variable power level and frequency Time – Doppler affects • Limited time to make measurements Frequency Carrier variance during one pass of satellite (LEO/MEO) 21
Slide 22: Real Time RF Management
Real Time RF Management LEO Constellations • Spectral Compliance – Accurately measure RF energy to show compliance with ITU ePFD requirements – Acquisition and algorithms are fast enough to mitigate effects of Doppler – Accurate time stamping of data acquisition – Show spectrum being used correctly
Slide 23: LEO/MEO Monitoring Concepts
LEO/MEO Monitoring Concepts • Constellations are a network • Frequency plans are site centric • RF spectrum is the transport of the network • To complex to monitor all RF spectrum in real-time with a human in the loop • New concepts for RF management and monitoring • Modem CQI does not indicate if n
