There's definitely a limit: Frequencies and orbital separation/steradians of aperture.
If you're putting a satellite right next to one of Starlink's, using the same frequency, how'd you communicate with it without the two interfering with each other?
Ah thank you. I’m assuming the product offering will be aimed at less frequent but more high value use cases such as remote navigation or sporadic messaging and infrequent short calls. Similar to other current satellite offerings for mobile devices, but hopefully enlarging the envelope of utility at least marginally.
