2. Background on ATC in L Band
L band is shared among multiple operators
Primarily Inmarsat and SkyTerra in United States
Current situation is that each uses small slices of interleaved spectrum that are not suitable for terrestrial systems
Inmarsat & MSV (now SkyTerra) entered into a Cooperation Agreement in December 2007 to rationalize spectrum between us in a way that would enable ATC
Harbinger has announced its intent to pursue ATC in the U.S. via acquisition of SkyTerra and Inmarsat
Harbinger has an agreement with SkyTerra but not Inmarsat

3. Challenges for ATC Capital, capital, capital
Gating criteria create complications compared to “clean” auctioned spectrum
Spectrum is shared between MSS & terrestrial
Integration requirement
What’s NOT a challenge:
Regulatory framework
Technical feasibility

4. Opportunities for ATC
While the freeze in capital markets will likely delay deployment of ATC in the near term, the longer term prospects are promising
Broadband applications will continue to suck up a lot of bandwidth
The “pipeline” for terrestrial spectrum is drying up
MSS has a unique ability to serve rural and remote underserved locations cost-effectively
National footprint is a huge advantage
Mobility and ubiquity will offer a comparative advantage

5. ATC on the road Europe has allocated spectrum for MSS at S band
The European proceeding specifically contemplates Complementary Ground Component (CGC) at S band
European selection of S band operators will be finalized shortly
European member states are developing CGC regulatory frameworks
