>So what does this mean? I understand more/less latency, but fast/slow latency? They mean lower latency. They're just using terminology that is more comprehensible to laymen. >I'm actually confused about why they need spectrum authorization at all Each country licenses spectrum within its geographic area. Most Starlink demand is inside the US due to low population density and high wealth to pay for service. This mostly maximizes the efficiency of spectrum use by auctioning it to the highest bidder and minimizing interference. Otherwise some fucktard in Wyoming would blast their pirate folk music station with three listeners across 100 mhz of spectrum. >Satellites don't broadcast wide signals, they usually send narrow beams that require a parabolic antenna. Signals bleed all over the place, albeit at weaker levels than at the intended destination. I've maintained succesful microwave links pointed at the *backside* of parabolic antennas because of this. >There's no way for satellite signals to interfere with terrestrial signals. They absolutely can and will. e.g. This is why frequencies used for radio-astronomy are often prohibited for orbital use, and for terrestrial use in broad geographic areas around radio telescopes.
