> If you've used old style satellite internet AST's satellite wasn't "old style satellite internet". It was at an altitude of 513km. That's roughly the same altitude as SpaceX's satellites (~550km). AST's satellite was absolutely "new technology", last September. SpaceX was beat for the "first phone service satellites", even for low orbit 5G satellites with unmodified phones. https://ast-science.com/2023/09/19/ast-spacemobile-achieves-... |

Looks like they used 800MHz, so basically the longest range cell phone bands. Which is about as expected, none of that super-fragile millimeter wave stuff.
SpaceX is using 1900MHz, which will make a difference but probably not a huge difference.
