Unfortunately, we have to plan based on current laws and Eagle needs to be
as small and light as possible so that we can afford two.
We're stuck when the FCC allocates our bands to millions of unlicensed
users. We can increase our power levels for terrestrial use, but its just
too expensive for HEO satellites.
