- trashtensor 3y agoI really don't understand the first paragraph, > Researchers in Switzerland have transmitted and received optical data at rates of more than 10 Tbit/s between an Alpine peak and an observatory at the University of Bern – a distance of 53 kilometres. This is more than five times further than would be needed to set up a satellite-to-ground communication link Google says Starlink satellites are 550km in altitude... Is this to do with turbulence below 10km?
- joecool1029 3y agoNot turbulence, air density. Oxygen molecules, dust/pollution, weather.... all of that attenuates light and RF.
- trashtensor 3y agoMakes sense, thanks.
