“Every user terminal pointed at that satellite receives every data packet sent in that beam”
Oh no no no, that sounds bad isn’t it, generally telcos avoid this problem by time and frequency modulation and providing a set of channels to each “terminal” where their data is sent and received, would that be possible for a fast moving “base station” in LEO? or is starlink a completely different system from my understanding.
- surender7522 6y agoUnderstood the writer meant electrical signal for receive. Does anyone know how they do latching and de registering of terminals at such speeds.
