this company claims there technology will work with existing cellular handset including indoors.
my understanding for years has been the laws of physics and limits of technology just does not make indoor connection to small antennas possible from that far away, especially from fast moving LEO satellites. but even AT&T seems to find them legit:
but if it really works as they say why only for dead spot coverage, at&t would be needed no more.
anyone more knowledgeable on the subject care to chime in ?
