This is using cell towers to relay to the satellites right? There were some companies trying to do direct cell to satellite and I didn't think it was feasible.

Direct from cell to sat, goal is deadzone free, global coverage

No, it's the latter of what you mentioned-- direct cell to SpaceX satellites

I thought existing Starlink needed a phased array antenna to get decent signal strength. How the hell is a cell phone radio going to reach a satellite?

This sounds like direct to satellite from existing handsets. I can imagine that LTE at 550km is possible but quite a feat of engineering.

This is actually fascinating. T-Mobile doesn’t need a fiber or even cable buildout to a remote location, just power and the local clearances for a tower, they plop a Starlink antenna on the top and bam. Congestion will be a challenge but it will be way better than the current status quo.

This needs no new towers, direct cell / sat comms with current phones

Gen 2 sats and a big antenna, will work with existing phones

This is definitely what I am interested in-- how existing cell HW can be picked up by their satellites. Even at low data rates for emergency SMS, etc. (caveat, I'm not a HW or radio engineer), this seems like an incredible feat if they can get it to work.

If they QoS common messaging apps and SMS, it'll be a massive win for a lot of people.

Won't that require a bunch of phone hardware for sat comms?

Maybe we're back to the days of lunchbox cell phones that get extremely hot and are questionably safe to hold next to your head.
